A(n) ____ reaction is one in which oxygen reacts with another compound to form carbon dioxide, water, and heat.

combustion fits.

oxidation fits
(but as a general statement this is not true of every reaction with oxygen.)

A(n) combustion reaction is one in which oxygen reacts with another compound to form carbon dioxide, water, and heat.

To identify a combustion reaction, you need to understand the components involved and what products are formed. In this case, the reaction involves oxygen and another compound, ultimately resulting in the formation of carbon dioxide, water, and heat.

To balance the combustion reaction equation, follow these steps:

1. Write the unbalanced equation:
Reactant + Oxygen (O2) → Carbon Dioxide (CO2) + Water (H2O)

2. Balance the carbon atoms:
Reactant + O2 → CO2 + H2O

3. Balance the hydrogen atoms:
Reactant + O2 → CO2 + 2H2O

4. Balance the oxygen atoms:
Reactant + O2 → CO2 + 2H2O
(Note: The number of oxygen atoms on the reactant side should match the total number of oxygen atoms in the product side.)

Once the equation is balanced, it represents a combustion reaction, where the reactant reacts with oxygen to form carbon dioxide, water, and release heat.
