When water is decomposed into hydrogen and oxygen, these gases cannot combine again to reform water?

1 answer:

6 0

This statement is false. When water is decomposed into hydrogen and oxygen; these gases are in a position of combining again to reform water. Water is a molecule consisting of one atom of oxygen bound to two hydrogen atoms. The atoms are joined by covalent bonds; however they have addition hydrogen bonds between the partial negative oxygen and the partial positive hydrogen atom.

1. Identify all of the gas law equations that relate to the ideal gas law.

zheka24 [161]

Explanation:

1) PV = nRT(ideal gas equation )

All of the gas laws equations that relate to the ideal gas law:

1. Boyle's law. This law states that pressure is directly proportional to the volume of the gas at constant temperature.

The equation given by this law is:

$P_1V_1=P_2V_2$

where,

$P_1\text{ and }V_1$ are initial pressure and volume.

$P_2\text{ and }V_2$ are final pressure and volume.

2. Charles' Law. This law states that volume of the gas is directly proportional to the temperature of the gas at constant pressure.

Mathematically,

$\frac{V_1}{T_1}=\frac{V_2}{T_2}$

where,

$V_1\text{ and }T_1$ are the initial volume and temperature of the gas.

$V_2\text{ and }T_2$ are the final volume and temperature of the gas.

3. Gay-Lussac Law. This law states that pressure of the gas is directly proportional to the temperature of the gas at constant pressure.

Mathematically,

$\frac{P_1}{T_1}=\frac{P_2}{T_2}$

where,

$P_1\text{ and }T_1$ are the initial pressure and temperature of the gas.

$P_2\text{ and }T_2$ are the final pressure and temperature of the gas.

4. Avogadro's law. This law states that volume is directly proportional to number of moles at constant temperature and pressure.

The equation used to calculate number of moles is given by:

$\frac{V_1}{n_1}=\frac{V_2}{n_2}$

where,

$V_1\text{ and }n_1$ are the initial volume and number of moles

$V_2\text{ and }n_2$ are the final volume and number of moles

Initial moles of gas = $n_1=0.0400 mol$

Initial volume of the gas = $V_1=500 mL=0.5 L (1 mL = 0.001 L)$

Final moles of gas = $n_2=?$

Final volume of the gas = $V_2=1.00 L$

Equation used to find the amount of gas added is Avogadro's law equation :

$\frac{V_1}{n_1}=\frac{V_2}{n_2}$

$n_2=\frac{V_2\times n_1}{V_1}=\frac{1.00 L\times 0.0400 mol}{0.5 L}$

$n_2=0.08 mol$

In an automobile's catalytic converter,

tia_tia [17]

The most of the pollutants (carbon monoxide, nitrogen monoxide and unburned hydrocarbons) are released from the car during the first one to two minutes after the car is started, and then decrease significantly after that, due to increasing the temperature which supply the system by heat that required to oxidize the released gases by increasing the rate of the chemical reaction.

Then, the correct answer is the temperature (B).
