using only reactants, what is the rate law for the reaction a 2b c --> ab2c ? step 1: a c --> ac (fast) step 2: ac b --> abc (slow) step 3: abc b --> ab2c (fast)
Answers
using only reactants The rate law in the given equation in the question is rate = k [A] [B}\(^{2}\)
The reaction is A + B ⇌ C (fast)
B + C --k2--→ D (slow)
The slow step controls how quickly the reaction occurs.
The rate equation can be found here.
rate = k[B][C]
Because C is not one of the reactants, there is a difficulty.
We must translate [C] into [A] and [B] in terms.
We are able to do it because an equilibrium is the first stage.
K = [C] [A][B]
∴ [C] = K [A] [B]
When we replace the initial rate expression, we obtain
rate = k2 [B] × K [A][B] = k2 K[A][B]2
Let
k = k2
K and the rate law becomes
rate = k [A][B]2

consider a 0.00550 m weak acid solution with a percent ionization of 8.20%. round each answer to two places past the decimal in scientific notation and for ph. part a: what is the concentration of h (in m) at equilibrium?
Answers
The concentration of H+ at equilibrium is 1.06 x 10^-4 M.
The concentration at equilibrium solutionTo determine the concentration of H+ in the weak acid solution at equilibrium, we need to use the percent ionization and the initial concentration of the weak acid.
Let's assume that the weak acid is denoted by HA. Then, we can write the equilibrium equation for the dissociation of HA as:
HA ⇌ H+ + A-
The equilibrium constant expression for this dissociation reaction is:
Ka = [H+][A-]/[HA]
Since the acid is weak, we can assume that the concentration of A- at equilibrium is approximately equal to the initial concentration of HA, since only a small fraction of HA is dissociated. Therefore, we can simplify the equilibrium constant expression to:
Ka = [H+]^2/[HA]
Rearranging this equation, we get:
[H+]^2 = Ka[HA]
Taking the square root of both sides, we get:
[H+] = sqrt(Ka[HA])
Now, we can plug in the values given in the problem:
Ka = unknown
[HA] = 0.00550 M
percent ionization = 8.20%
To find Ka, we can use the percent ionization:
percent ionization = [H+]/[HA] x 100%
8.20% = [H+]/0.00550 M x 100%
[H+] = 0.000451 M
Now, we can use the equation we derived earlier to find [H+] at equilibrium:
[H+] = sqrt(Ka[HA])
0.000451 M = sqrt(Ka x 0.00550 M)
Squaring both sides, we get:
Ka x 0.00550 M = (0.000451 M)^2
Solving for Ka, we get:
Ka = (0.000451 M)^2 / 0.00550 M
Ka = 3.70 x 10^-6 M
Finally, we can use the equation [H+] = sqrt(Ka[HA]) to find the concentration of H+ at equilibrium:
[H+] = sqrt(3.70 x 10^-6 M x 0.00550 M)
[H+] = 1.06 x 10^-4 M
Therefore, the concentration of H+ at equilibrium is 1.06 x 10^-4 M.

How does the formation of water from hydrogen and oxygen demonstrate the conservation of mass?
Answers
Answer:
Well, the mass of the products is equal to the mass of the reactants.
Explanation:
The law of conservation of mass states that,
For any system closed to all transfers of matter and energy, the mass of the system must remain constant over time, as system's mass cannot change, so quantity cannot be added nor removed.
Taken from here.
Suppose we have the balanced equation of combustion of hydrogen to form water.
The equation will be:
2H2(g)+O2(g)→2H2O(g)
Now, we look at the total mass of the reactants and compare it with the mass of the products.
H2 has a mass of 1⋅2 amu, and so 2H2 will have a mass of 2⋅2=4 amu.
O2 has a mass of 16⋅2=32 amu.
So, the total mass of the reactants (2H2+O2) is equal to 4+32=36 amu.
Now, let's take a look at the mass of the products.
Water has a chemical formula of H2O.
In here, there are two hydrogen atoms and one oxygen atom, and so its mass will be 2+16=18 amu.
There are two water molecules formed, and that means the total mass of the products is 18⋅2=36 amu.
As you can see now, the mass of the products is equal to the total mass of the reactants together, and the chemical equation obeys the law of conservation of mass.
Note that this applies to every balanced chemical equation.
If you prepare a solution by dissolving 25,38 g of iodide in 500g of water, what is the molality of the solution?
Answers
The molality of the solution is 0.686 mol/kg.
How does molality differ from other concentration units such as molarity and mass percent?Molality is a concentration unit that describes the number of moles of solute per kilogram of solvent. Molarity describes the number of moles of solute per liter of solution, while mass percent describes the mass of solute per 100 grams of solution.
Molality is preferred when changes in temperature or pressure can significantly affect the volume of the solution, since it is based on the mass of solvent rather than the volume.
Why might molality be a preferred unit for certain types of chemical reactions or experiments?Molality may be a preferred unit for certain types of chemical reactions or experiments because it is a measure of the number of moles of solute per kilogram of solvent, which is independent of temperature and pressure.
This makes it useful for reactions that require precise control of the concentration of the solute, such as in cryogenic reactions or in reactions that are highly sensitive to changes in temperature or pressure.

Answers
Therefore the correct option is D. As a pot of soup is placed on a hot burner, thermal energy is transferred from the burner to the pot.
This causes the pot to heat up and as a result, the thermal energy is then transferred from the pot to the soup. This process continues until the soup reaches its boiling point. Once the soup begins to boil, thermal energy is still being transferred from the burner to the pot and soup, but at a slower rate. As the soup continues to boil, some of the thermal energy is transferred from the soup to the air surrounding it, which is why we see steam rising from the pot.

what is the effect on the concentrations of no-2, hno2, oh and when is added to a solution of in water. the equation for the equilibrium is:
Answers
When water is added to a solution with NO2- and HNO2, the concentration of NO2- will increase, the concentration of HNO2 will decrease, and the concentration of OH- will increase.
The addition of water to a solution will have different effects on the concentrations of NO2-, HNO2, and OH-.
1. NO2- (nitrite ion):
When water is added to the solution, it will dissociate into H2O and NO2-. This will increase the concentration of NO2- in the solution, as water acts as a source of NO2- ions.
2. HNO2 (nitrous acid):
The equilibrium equation suggests that HNO2 is formed when NO2- reacts with H2O. However, the addition of water will cause the concentration of HNO2 to decrease. This is because the reaction between NO2- and H2O favors the formation of NO2- rather than HNO2. So, the increase in the concentration of NO2- will decrease the concentration of HNO2.
3. OH- (hydroxide ion):
The addition of water will increase the concentration of OH-. Water naturally contains OH- ions, so the presence of water will increase the concentration of OH- in the solution.
changes occur due to the equilibrium between NO2- and HNO2, as well as the dissociation of water to form OH- ions.
It's important to note that the specific changes in concentrations will depend on the initial concentrations of NO2-, HNO2, and OH- ions, as well as the equilibrium constants involved in the reactions.

A) 0.300 mol
B) 0.100 mol
C) 0.0300 mol
D) 0.0100 mol
Answers
Answer:
The answer is C) 0.0300 mol
Explanation:
First you need to get the total amount of moles is dissolved in the solution. This can be obtained doing the following:
Molarity = moles of solute / liters of solution
moles of solute = molarity x liters of solution
First, the volume has to be in liters, then :
100. ml x (1 L / 1000 mL) = 0.100 L
(We then substitute)
moles of solute = 0.100 mol/L x 0.1 L = 0.0100 mol of solute (In this case Na3PO4)
Having the moles of the solute, we now need to find how many moles of Na+ ions are there.
We need the conversion factor of 3 Na+ moles per 1 mole of Na3PO4
We then find the amount of moles doing as follows:
0.0100 mol Na3PO4 x (3 mol Na+ / 1 mol Na3PO4) = 0.0300 mol Na+.
The number of moles of \(Na^+\) are 0.0300 and further calculation can be defined as follows:
Given that:
Molarity of \(Na_3PO_4\) = 0.100 M
Volume of a solution = 100. mL
To find:
Moles of \(Na^+\) ions
Formula used to calculate the number of moles when molarity is given is:
\(\text{Molarity of solution}=\frac{\text{Moles of solute}\times 1000}{\text{Volume of solution (mL)}}\)
Put the values in the above formula:
\(0.100M=\frac{\text{Moles of }Na_3PO_4\times 1000}{100 mL}\\\\\text{Moles of }Na_3PO_4=\frac{0.100\times 100}{1000}\\\\\text{Moles of }Na_3PO_4=0.01 moles\)
Since, 1 mole of \(Na_3PO_4\) contains 3 moles of \(Na^+\) and 1 mole of \(PO_4^{3-}\) ions.
Moles of \(Na^+\) ions = \((3\times 0.0100)=0.0300mol\)
So, the required moles of \(Na^+\) ions are 0.0300 moles.

Calculate the amount of heat (in kJ) that must be absorbed to convert 108 g of ice at 0oC to water at 70oC.
Answers
"The amount of heat that must be absorbed to convert 108 g of ice at 0°C to water at 70°C is approximately 68.12 kJ."
To calculate the amount of heat required to convert ice at 0°C to water at 70°C, we need to consider two steps:
Heat required to raise the temperature of ice from 0°C to its melting point (0°C).
Heat required to melt the ice at its melting point (0°C) and raise the temperature of water from 0°C to 70°C.
Let's calculate the heat for each step:
Step 1: Heating ice from 0°C to its melting point (0°C)
The specific heat capacity of ice is 2.09 J/g°C.
Heat = mass × specific heat capacity × change in temperature
Heat = 108 g × 2.09 J/g°C × (0°C - 0°C)
Heat = 0 kJ (No heat is absorbed as there is no change in temperature)
Step 2: Melting ice and heating water from 0°C to 70°C
The enthalpy of fusion (heat of fusion) for ice is 334 J/g, which represents the amount of heat required to melt ice at 0°C.
Heat for melting ice = mass × enthalpy of fusion
Heat for melting ice = 108 g × 334 J/g
Heat for melting ice = 36,072 J
Next, we need to calculate the heat required to raise the temperature of the water from 0°C to 70°C.
The specific heat capacity of water is 4.18 J/g°C.
Heat = mass × specific heat capacity × change in temperature
Heat = 108 g × 4.18 J/g°C × (70°C - 0°C)
Heat = 32,043.6 J = 32.04 kJ
Now, we can sum up the heat required for both steps:
Total heat = Heat for melting ice + Heat for raising water temperature
Total heat = 36,072 J + 32,043.6 J
Total heat = 68,115.6 J = 68.12 kJ
Therefore, the amount of heat that must be absorbed to convert 108 g of ice at 0°C to water at 70°C is approximately 68.12 kJ.

what is the refrigerants state when entering the metering device
Answers
When refrigerant is in a high-pressure, high-temperature state, it enters the metering device. The refrigerant is then changed to a low-pressure, low-temperature state as a result of the metering device. As a result, the refrigerant will expand and the heat will be absorbed as the temperature decreases.
The metering device is a component in a refrigeration or air conditioning system that ensures that the correct amount of refrigerant is delivered to the evaporator. The device functions as a flow control, reducing the refrigerant's pressure before it reaches the evaporator. The metering device may be a simple capillary tube, an orifice, an automatic expansion valve (AEV), or a thermostatic expansion valve (TXV). The capillary tube is the simplest and least expensive metering device. It's just a small copper tube that's thin and long. The AEV is a constant pressure valve that maintains a consistent pressure drop across it, allowing it to regulate the refrigerant flow. A thermostatic expansion valve is the most sophisticated metering device, as it can sense the temperature at the evaporator outlet and adjust the refrigerant flow accordingly.

Answers
The false statement is Option (d)
d) Suppose you were 60ft beneath the surface of ocean scuba diving and took a deep breath of air from your tank and held your breath. It is a good idea to start ascending without exhaling.
If you hold your breath while ascending to the surface, your lungs and the air within them expands as the water pressure weakens. since the air has no place to get out it will be pressurized between the wall of the lungs. It gets keep on swelling between the walls of the lungs .
Frequent changes in the pressure of the air which is present in the walls of the lungs during the ascending or descending without exhaling can cause a serious lung injury.
