Question

question 5 of 10
what does the model below represent?
2co + o₂ → 2co₂
a. the production of oxygen
b. a release of heat
c. a chemical reaction
d. an experiment

Explanation:

The given equation $2CO + O_2
ightarrow 2CO_2$ shows carbon - monoxide reacting with oxygen to form carbon - dioxide. This is a typical representation of a chemical reaction where reactants (CO and $O_2$) are transformed into products ($CO_2$). It does not represent the production of oxygen (oxygen is a reactant here), nor does it inherently show a release of heat (although many combustion reactions like this one are exothermic, the equation alone doesn't indicate heat release), and it is not an experiment but rather a symbolic representation of a chemical change.

Answer:

C. A chemical reaction
