what is 1006 in scientific notation?

Aluminum ion has a charge of 3+, Al³⁺, and sulfate is SO₄²⁻, so the compound aluminum sulfate has to have a number of aluminum and sulfate such that the final charge is zero, so the proportion on aluminum sulfate is:

That way we have 6+ and 6-, so neutral compound.

This means that for 1 mol of aluminum sulfate, we have 2 moles of aluminum ion. The molar concentration is the number of moles of solute divided by the volume of solution, so it is directly proportional to the number of moles.

So, we can use a rule of three as follows:

aluminum ion --- aluminum sulfate

2 --- 1

x --- 0.646 M

So:

So, the concentration of aluminum ion in this solution is 1.292 M.

The statement that is turns phenolphthalein pink indicates a base, conduct an electrical current in solution indicates both acid and base, tastes sour indicates an acid, neutralizes acids indicates a base, and turns litmus paper blue indicates a base.

Phenolphthalein is a pH indicator used to determine whether the solution is acidic or basic. It turns pink in the basic solution when the pH is above 8.2.

Both acidic and basic solutions can conduct electricity as both contain ions that facilitate the flow of an electric current. Base when dissolved in the water releases the hydroxide ions (OH⁻) which acts as a charge carrier. Similarly, acids when dissolved in the water releases the hydrogen ions (H⁺) which acts as a charge carrier and thus conducts electricity.

Acids tend to have a sour taste due to the presence of hydrogen ions (H+).

Bases are substances that neutralize acids in a reaction, producing water and a salt. Neutralization is a reaction in which acid reacts with a base to form a salt and water.

Litmus paper is a pH indicator that turns blue in the presence of a base (pH greater than 7).

The curve represents saturation. Below the curve, the water is unsaturated. Above the curve, water is supersaturated. This means that more solute is present than the water can contain.

The line of the solubility curve indicates that the solution is saturated. A saturated solution is defined as a solution in which 100 g of solute is dissolved in 100 g of water. Simulations below this line indicate unsaturated solutions.

The difference between unsaturated and saturated solutes can be determined by adding very small amounts of solute to the solution. In unsaturated solutes, solutes will dissolve, and solutes in saturated solutes will not dissolve. In saturated solutes, crystals will form very quickly around the added solute.

This is a stoichiometry question, and will be answered in two steps, but the first thing for every stoichiometry question is to have the reaction properly balanced, which the question already provided us:

S8 + 8 O2 -> 8 SO2

First step is to find the limiting and excess reactant, this will tell us which element is in excess and by how much, let's gather the data for the reactants first:

30.14 grams of S8, molar mass of S8 is 256.5g/mol

287.43 grams of O2, molar mass of O2 is 32g/mol

Now we will focus on S8, and see how many moles we have of it in this reaction:

256.5 g = 1 mol

30.14 g = x moles

x = 0.12 moles of S8 in this reaction

According to the molar ratio, 1:8, we need 1 mol of S8 and 8 moles of O2 in order to have the reaction to proceed

1 S8 = 8 O2

0.12 S8 = x O2

x = 0.96 moles of O2 if we have 0.12 moles of S8

We only need 0.96, if we have more than that, is excess, if we have less than that, this means that O2 is the limiting and S8 is in excess, so let's check how much of O2 we do have

32g = 1 mol

287.43 g = x moles

x = 8.98 moles of O2, we have a big excess of O2, we only need 0.96 moles and we have almost 9 times more

Now that we know which element is the limiting, we can use this information to find the theoretical yield of SO2

The molar ratio will also be 1:8, and since we have 0.12 moles of S8, we will have 8 times that, which is 0.96 moles of SO2, using its molar mass, 64.1g/mol, we will have the theoretical yield

64.1g = 1 mol

x grams = 0.96

x = 61.5 grams is the theoretical yield

55.59 grams is the actual yield

Now we use these two values in the percent yield formula:

%yield = actual yield/theoretical yield

%yield = 55.59/61.5

%yield = 0.90

Limiting reactant = S8

Excess reactant = O2

Percent yield = 90%

The density of the substance having a mass of 2.0 g is 0.4 g/mL (Option D)

Volume of substance = (Volume of water + substance) - (Volume of water)

Volume of substance = 75 - 70

Volume of substance = 5 mL

Finally, we shall determine the density of the substance. This is illustrated below:

Density = mass / volume

Density of substance = 2 / 5

Density of substance = 0.4 g/mL

Thus, the density is 0.4 g/mL (Option D)

Explanation:

Using the root-mean-square (RMS) speed formula, we find that the average speed of 1 mole of hydrogen molecules at 300 K is approximately 2057 m/s. The correct option is C). The most probable speed among the given set of particle speeds is 5 m/s. The correct option is C).

The root-mean-square (RMS) speed formula is :

v_rms = sqrt((3 * k * T) / (molar mass))

where:

v_rms is the root-mean-square speed

k is the Boltzmann constant (1.38 * 10^-23 J/K)

T is the temperature in Kelvin

molar mass is the mass of one mole of hydrogen molecules

First, we calculate the molar mass of hydrogen (H2):

molar mass = 2 * (mass of one proton) = 2 * (1.67 * 10^-27 kg) = 3.34 * 10^-27 kg

Now, we substitute the values into the formula:

v_rms = sqrt((3 * 1.38 * 10^-23 J/K * 300 K) / (3.34 * 10^-27 kg))

Calculating this expression gives us:

v_rms ≈ 2057 m/s

Therefore, the correct option is C).

The most probable speed is calculated by finding the speed at which the maximum number of particles are moving. The most probable speed is given by the peak of the Maxwell-Boltzmann distribution.

In this case, we have the following speeds: 2, 3, 4, 5, 5, 5, 6, 6, 7, and 9 m/s.

To find the most probable speed, we identify the speed that occurs most frequently. We count the frequencies of each speed:

Speed: 2 3 4 5 6 7 9

Count: 1 1 1 3 2 1 1

The speed 5 occurs the most frequently (count = 3), so the most probable speed is 5 m/s. Therefore, the correct option is C).

If the funnel's size is less than the flask's opening, the oil flow will be diminished, and after a period, the oil may stop flowing altogether due to the pressure.

When Emily poured oil into a sealed flask through a funnel, she noticed that the oil flowed slowly and eventually stopped flowing altogether. This happened because the air trapped inside the flask pushed back on the surface of the oil.

The air pressure inside the flask rose as more oil was added, slowing the oil flow. The oil gradually stopped pouring as the pressure inside the flask reached its equilibrium with the pressure outside. The pressure equilibrium is what is being described here.

To give a basic idea of the arrangement of a compound, the best formula to use is the structural formula. The structural formula shows the arrangement of atoms and the bonds between them, which gives a visual representation of the molecule's shape.

The molecular formula only provides information on the number and type of atoms in the molecule. The empirical formula provides the simplest ratio of atoms in the molecule, but does not show the arrangement or connectivity of the atoms. The baby formula is a completely unrelated term and is not relevant to chemistry or molecule representation.

Therefore, to show the arrangement of atoms and bonds in a molecule, the structural formula is the best choice.

Answer:

a) The half-life of the reaction is approximately 3.3 hours.

b) It will take approximately 10.8 hours for a 2.5 M solution of sucrose to hydrolyze until a 0.10 M solution remains.

The hydrolysis of sucrose is a first-order reaction, which means that its rate depends on the concentration of the sucrose itself. The rate constant, denoted by k, is a proportionality constant that links the rate of the reaction to the concentration of the reactant.

a) To determine the half-life of the reaction, we use the formula t1/2 = (0.693/k), where t1/2 is the half-life and k is the rate constant. Substituting the given value of k, we get:

t1/2 = (0.693/0.21) hr ≈ 3.3 hr

Therefore, the half-life of the reaction is approximately 3.3 hours.

b) To determine how long it will take for a 2.5 M solution of sucrose to hydrolyze until a 0.10 M solution remains, we use the first-order integrated rate law, which relates the concentration of the reactant to the elapsed time of the reaction. The integrated rate law for a first-order reaction is given by:

ln([A]t/[A]0) = -kt

where [A]t is the concentration of the reactant at time t, [A]0 is the initial concentration of the reactant, k is the rate constant, and ln is the natural logarithm.

Rearranging the above equation, we get:

t = (ln[A]0 - ln[A]t) / k

Substituting the given values, we get:

t = (ln(2.5) - ln(0.10)) / 0.21 ≈ 10.8 hours

Therefore, it will take approximately 10.8 hours for a 2.5 M solution of sucrose to hydrolyze until a 0.10 M solution remains.
