A decomposition occurs when you open a can or bottle of soda. Carbonic acid, H2CO3, is in carbonated beverages. It decomposes into carbon dioxide and water. If you leave an open soda can out for a long time, it loses its fizz. Which equation represents the balanced chemical equation for this reaction?

H₂CO₃ (aq) → CO₂ (g) + H₂O (l)

Explanation:

Step 1: Write out unbalanced decomposition equation

H₂CO₃ (aq) → CO₂ (g) + H₂O (l)

Step 2: Balance equation

We see that we have 3 oxygens on both sides of the reaction.

We also see that we have 1 carbon on both sides of the reaction.

We also see that we have 2 hydrogens on both sides of the reaction.

Therefore, the chemical equation is balanced.

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.
