Question

missed this? watch kcv: writing and balancing chemical equations iwe: balancing chemical equations. read sections 7.3, 7.6. you can click on the review link to access the section in your etext. complete and balance each of the following combustion reaction equations. part a c(s) + o₂(g) → express your answer as a complete chemical equation including phases. a chemical reaction does not occur for this question.

Explanation:

Step1: Determine the product

Carbon (C) reacts with oxygen (\(O_2\)) in a combustion reaction to form carbon dioxide (\(CO_2\)). So the un - balanced equation is \(C(s)+O_2(g)\to CO_2(g)\)

Step2: Check the balance of atoms

• For carbon (C): There is 1 C atom on the left - hand side (LHS) (\(C(s)\)) and 1 C atom on the right - hand side (RHS) (\(CO_2(g)\)).
• For oxygen (O): There are 2 O atoms on the LHS (\(O_2(g)\)) and 2 O atoms on the RHS (\(CO_2(g)\))

Answer:

\(C(s)+O_2(g)\to CO_2(g)\)
