1)The new volume at a pressure of 1 atm is 0.25 L.

2)The new temperature of the container at a volume of 2 L is approximately 398°C.

3)The new pressure at 2.5 L is approximately 4.8 atm.

4)The new volume at a temperature of 60°C is approximately 55.8

1)To solve these gas law problems, we can use the ideal gas law equation, which states:

PV = nRT,

where P is pressure, V is volume, n is the number of moles of gas, R is the ideal gas constant, and T is temperature in Kelvin.

Balloon volume at a pressure of 0.5 atm:\(V_1\) = 0.5 L, \(P_1\)= 0.5 atm.

New volume at a pressure of 1 atm:\(P_2\) = 1 atm.

We can use the relationship\(P_1V_1 = P_2V_2\) to find the new volume (\(V_2\)).

(0.5 atm)(0.5 L) = (1 atm)(\(V_2\))

\(V_2\) = 0.25 L.

Therefore, the new volume at a pressure of 1 atm is 0.25 L.

2)Container volume: \(V_1\) = 2 L, \(T_1\)= 125°C.

New temperature at the same volume: \(V_2\) = 2 L.

We can use the relationship\(V_1\)/\(T_1\) = \(V_2\)/\(T_2\) to find the new temperature (\(T_2\)).

(2 L)/(125 + 273) K = (2 L)/(\(T_2\) + 273) K

Solving for\(T_2\), we get \(T_2\) ≈ 398°C.

Therefore, the new temperature of the container at a volume of 2 L is approximately 398°C.

3)Initial volume: \(V_1\)= 4.0 L, \(P_1\) = 3.0 atm.

Final volume: \(V_2\) = 2.5 L.

Since the temperature (T) is constant, we can use the relationship \(P_1\)\(V_1\) = \(P_2V_2\) to find the new pressure (\(P_2\)).

(3.0 atm)(4.0 L) = (\(P_2\))(2.5 L)

\(P_2\) ≈ 4.8 atm.

Therefore, the new pressure at 2.5 L is approximately 4.8 atm.

4)Initial volume: \(V_1\)= 50 mL, \(T_1\) = 25°C.

New temperature: \(T_2\) = 60°C.

We need to convert the temperatures to Kelvin.

\(T_1\)= 25 + 273 = 298 K, \(T_2\) = 60 + 273 = 333 K.

We can use the relationship \(V_1/T_1 = V_2/T_2\) to find the new volume (\(V_2\)).

(50 mL)/(298 K) = (\(V_2\))/(333 K)

\(V_2\) ≈ 55.8 mL.

Therefore, the new volume at a temperature of 60°C is approximately 55.8

Atoms are the building blocks of matter.

They are the smallest particles of an element that still have the element's properties.

All atoms are very small, but atoms of different elements vary in size.

Three main types of particles that make up all atoms are protons, neutrons, and electrons.

Answer:

Sound requires a medium to move through; light does not.

Sound and light are similar in that both are forms of energy that travel in waves.

Explanation:

Sound and light are similar in that both are forms of energy that travel in waves. They both have properties of wavelength, freqency and amplitude. Sound can only travel through a medium (substance) while light can travel through empty space. Sound is a form of mechanical energy caused by vibrations of matter.

Light waves DO NOT require a medium, they travel fastest in empty space; Sound waves REQUIRE a medium, they travel fastest in dense material like solids. Sound is a longitudinal wave.

Explanation:

The volume of carbon dioxide produced is approximately (d) 11.9 liters.

To determine the amount of carbon dioxide (C\(O_2\)) produced when 37.8 grams of carbon disulfide (C\(S_2\)) reacts with excess oxygen gas (\(O_2\)), we need to use stoichiometry and the given balanced chemical equation:

C\(S_2\)(l) + 3\(O_2\)(g) → C\(O_2\)(g) + 2S\(O_2\)(g)

First, we calculate the number of moles of C\(S_2\) using its molar mass:

Molar mass of (C\(S_2\)) = 12.01 g/mol (C) + 32.07 g/mol (S) × 2 = 76.14 g/mol

Number of moles of (C\(S_2\)) = mass / molar mass = 37.8 g / 76.14 g/mol ≈ 0.496 mol

From the balanced equation, we can see that the stoichiometric ratio between (C\(S_2\)) and C\(O_2\) is 1:1. Therefore, the number of moles of C\(O_2\) produced will also be 0.496 mol.

Now we can use the ideal gas law to calculate the volume of C\(O_2\) at the given temperature and pressure. The ideal gas law equation is:

PV = nRT

where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant (0.0821 L·atm/mol·K), and T is the temperature in Kelvin.

Converting the temperature from Celsius to Kelvin:

T(K) = 28.85°C + 273.15 = 302 K

Using the ideal gas law:

V = nRT / P = (0.496 mol) × (0.0821 L·atm/mol·K) × (302 K) / (1.02 atm) ≈ 11.9 L

The correct answer is 11.9 liters.

The reaction which occurs between acids and bases - neutralization

We know that the pH of a solution has to do with the amount of the acidity and the alkalinity of a solution. We know that the pH scale has been calibrated from 0 - 14. The range of the values from 0 -6 has been classed as as acidic. The number 7 has been shown to be a neutral solution while the numbers 8 - 14 has been shown to be a basic solution.

According to the law of reciprocal proportions, they should combine in the ratio of 10.24:7.92:1.29 by mass.

According to the law of reciprocal proportions when two elements join to form more than one compound, the weights of one element that combine with a fixed weight of the another are in a ratio of small whole numbers.

In phosphine, phosphorus = 91.1 parts and hydrogen = 8.9 parts

So, 8.9 pads of hydrogen combine with phosphorus = 91.1 parts .

1 part of hydrogen combine =  91.1 / 8.9

= 10.24 parts

Similarly,

for water 88.8 / 11.2

= 7.92 parts of hydrogen

For Phosphorus tetra oxide

The chemical formula for the molecule you provided is C2H5Cl.

In the molecule, the central atom is carbon (C), which is bonded to two hydrogen atoms (H) and one chlorine atom (Cl). The carbon atom forms single bonds with each of the hydrogen and chlorine atoms, resulting in a linear structure.

To write the chemical formula, we start by indicating the number of atoms of each element present in the molecule. In this case, there are two carbon atoms (C2), five hydrogen atoms (H5), and one chlorine atom (Cl1).

Next, we write the symbols for the elements in the order of their appearance. The formula is typically written with the carbon atom first, followed by hydrogen, and then any other elements in alphabetical order. Therefore, the chemical formula for the molecule is C2H5Cl.

The subscripts in the formula indicate the number of atoms of each element in the molecule. In this case, there are two carbon atoms, five hydrogen atoms, and one chlorine atom.

It's important to note that the formula represents the simplest ratio of atoms in the molecule. It does not provide information about the spatial arrangement or bonding pattern of the atoms. Additional structural information, such as the arrangement of atoms in space, would require a more detailed representation, such as a Lewis structure or a three-dimensional model.

Stoichiometry is the calculation of the quantities of reactants and products in a chemical reaction. It involves balancing the chemical equation, determining the moles of reactants and products, and using mole ratios to find the desired quantities.

We have that;

Number of moles of oxygen = 62.3 g/32 g/mol

= 1.9 moles

If 5 moles of oxygen produces 44.8 L of water

1.9 moles of oxygen will produce 1.9 * 44.8/5

The heat absorbed by the engine block when its temperature is raised from 20°C to 90°C is 665,640 J.

To calculate the heat absorbed by the engine block, we can use the equation:

Q = mcΔT

where Q is the heat absorbed, m is the mass of the engine block, c is the specific heat capacity of steel, and ΔT is the change in temperature.

First, we need to calculate the specific heat capacity of steel. The specific heat capacity of steel is typically around 0.45 J/g°C.

Using this value and the given values of mass and temperature change, we can calculate the heat absorbed by the engine block as follows:

Q = (21080 g) x (0.45 J/g°C) x (90°C - 20°C)

Q = 21080 g x 0.45 J/g°C x 70°C
