Question

5. Base your answer to the following question on the informationbelow and on your knowledge of chemistryA metal worker uses a cutting torch that operates by reactingacetylene gas, C2H2(g), with oxygen gas, O2(g), as shown inthe unbalanced equation below.CH,(g) + 0,(g) → CO2(g) + H2O(g) + heat

Answer 1

In order to properly balance an equation, we need to make sure that the same amount of elements on the reactants side matches the number of elements on the products side, we can do that by increasing the number in front of each molecule, the so called stoichiometric coefficient.

The proper balancing for this question is:

2 C2H2 + 5 O2 -> 4 CO2 + 2 H2O

Therefore the coefficients are:

2, 5, 4, 2
