Question

Which reaction below represents a balanced, combustion chemical reaction?
A) C2H5OH + 3O2 → 2CO2 + 3H2O
B) C2H5OH + 3O2 → 2CO + 3H2O
C) Li2CO3 → Li2O + CO2
D) 2Li + 2H2O → 2LiOH + H2

Answer 1

I believe the correct answer would be C2H5OH + 3O2 → 2CO2 + 3H2O . A combustion reaction is one that reacts with oxygen and produces carbon dioxide and water. As you can see, option A falls into that category and is a balanced reaction.

Answer 2

Pretty sure the answer is A
