Explanation:

Step1: Count atoms in reactants

For \(6CO_{2}\): \(C = 6\), \(O=12\). For \(6H_{2}O\): \(H = 12\), \(O = 6\). Total \(C=6\), \(H = 12\), \(O=18\).

Step2: Count atoms in products

For \(6O_{2}\): \(O = 12\). For \(C_{6}H_{12}O_{6}\): \(C = 6\), \(H = 12\), \(O = 6\). Total \(C=6\), \(H = 12\), \(O=18\).

Step3: Analyze chemical equation meaning

The arrow in \(6CO_{2}+6H_{2}O
ightarrow6O_{2}+C_{6}H_{12}O_{6}\) means the reactants \(6CO_{2}\) and \(6H_{2}O\) react to form the products \(6O_{2}\) and \(C_{6}H_{12}O_{6}\).

Answer:

• Reactants (left - side): \(C = 6\), \(H = 12\), \(O=18\)
• Products (right - side): \(C = 6\), \(H = 12\), \(O=18\)
• Arrow meaning: Reactants yield products.
