Question

Plumbers, welders, or glass blowers often use the gas acetylene (C2H2) because it burns in oxygen with a very hot flame. The products of the combustion of acetylene are carbon dioxide and water vapor. Write the unbalanced chemical equation for this process. (Include states-of-matter under the given conditions in your answer.)

Answer 1

Unbalanced equation:
`C_(2)H_(2)(g)+O_(2)(g)\rightarrow CO_(2)(g)+H_(2)O(g)`

Step-by-step explanation:

• Acetylene reacts with oxygen to produce carbon dioxide and water vapor.
• Here reactants are acetylene and oxygen. Here products are carbon dioxide and water vapor.
• We know that physical state of water vapor is gas. Therefore each and every reactants and products are gaseous.
• States of the species in unbalanced equation is represented inside parentheses with an abbreviation "g" for gaseous state.
• Unbalanced equation:
  `C_(2)H_(2)(g)+O_(2)(g)\rightarrow CO_(2)(g)+H_(2)O(g)`
