The atoms and molecules in a gas are in constant motion. Temperature is a measure of this motion. How are these related? As temp
Sedaia [141]

Here we have to choose the correct statement on the effect of temperature on the motion of the molecules and atoms of a gas.

As the temperature increases the molecules and atoms move faster.

As per the kinetic theory of gas molecules and atoms the kinetic energy (K.E.) of the atom or molecules is related to temperature by the equation

K.E. = \frac{3}{2}kT ( k = Boltzmann constant, T = temperature.

Thus as the temperature increases the K.E. increases thus the atom or molecules move faster.

With the decrease of temperature the movement of the atoms or molecules will be less and they will be near to each other.

The increment of temperature increase the K.E. thus the atoms or molecules move apart from each other.

With the decrease of temperature the movement of the atoms or molecules decreases.

If 1.320 moles of CH4 reacts completely with oxygen, how many grams of H2O can be formed
Rainbow [258]

Answer:

47.5 g of water can be formed

Explanation:

This is the reaction:

CH₄  +  2O₂  →  CO₂ + 2H₂O

Methane combustion.

In this process 1 mol of methane react with 2 moles of oxygen to produce 2 moles of water and 1 mol of carbon dioxide.

As ratio is 1:2, I will produce the double of moles of water, with the moles of methane I have.

1.320 mol  .2 = 2.64 moles

Now, we can convert the moles to mass (mol . molar mass)

2.64 mol . 18g/mol = 47.5 g
