Problem PageQuestion Acetylene gas is often used in welding torches because of the very high heat produced when it reacts with o

xygen gas, producing carbon dioxide gas and water vapor. Calculate the moles of acetylene needed to produce 2.00 mol of water. Be sure your answer has a unit symbol, if necessary, and round it to the correct number of significant digits.

<u>Answer:</u> The amount of acetylene gas needed in the reaction is 2.00 moles

<u>Explanation:</u>

We are given:

Moles of water = 2.00 moles

The chemical equation for the reaction of acetylene with oxygen gas follows:

2C_2H_2+5O_2\rightarrow 4CO_2+2H_2O

By Stoichiometry of the reaction:

2 moles of water is produced by 2 moles of acetylene gas

So, 2.00 moles of water will be produced by = \frac{2}{2}\times 2.00=2.00mol of acetylene gas

Hence, the amount of acetylene gas needed in the reaction is 2.00 moles
