From this combustion equation, 2CH22 + 3102 - 22H,0 + 2000, calculate the liters of
carbon dioxide produced when 16.9 grams of CH are combusted

Answer : The volume of produced are, 26.7 liters.

Explanation :

First we have to calculate the moles of

Now we have to calculate the moles of .

The given combustion reaction is:

From the balanced chemical reaction we conclude that,

As, 2 moles of react to give 20 moles of

So, 0.119 moles of react to give moles of

Now we have to calculate the volume of produced.

As we know that, 1 mole of gas occupies 22.4 L volume of gas.

As, 1 mole of gas occupies 22.4 L volume of gas.

So, 1.19 mole of gas occupies 1.19 × 22.4 L = 26.7 L volume of gas.

Therefore, the volume of produced are, 26.7 liters.

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.
