Question

1. a chemical reaction occurs when a student puts carbon dioxide (co₂) and water (h₂o) together. co₂ + h₂o → ?

Explanation:

Step1: Recall the reaction of CO₂ and H₂O

Carbon dioxide (\(CO_2\)) reacts with water (\(H_2O\)) to form carbonic acid (\(H_2CO_3\)). The chemical equation is based on the combination of these two compounds, where the atoms rearrange to form the new compound.

Step2: Write the balanced equation

The reaction is \(CO_2 + H_2O
ightarrow H_2CO_3\). We check the number of each atom on both sides: on the left, C:1, O: \(2 + 1 = 3\), H:2. On the right, in \(H_2CO_3\), C:1, O:3, H:2. So the equation is balanced as written.

Answer:

\(CO_2 + H_2O
ightarrow H_2CO_3\) (The product is carbonic acid, with the chemical formula \(H_2CO_3\))
