Question

question 1
match each description with the term or formula given.

1. in the formula, 2h₂ + o₂ → 2h₂o, 2h₂ + o₂ are the
2. in the formula, 2h₂ + o₂ → 2h₂o, 2h₂o is the
3. in the formula, c₆h₁₂o₆ + 6o₂ → 6co₂ + 6h₂o, 6co₂ + 6h₂o is the
4. in the formula, c₆h₁₂o₆ + 6o₂ → 6co₂ + 6h₂o, c₆h₁₂o₆ + 6o₂ are the
5. are the elements or compounds that enter into a chemical reaction.
6. are the substance(s) formed in a chemical reaction.

Explanation:

In a chemical equation, the substances on the left - hand side of the arrow are reactants (they enter into the chemical reaction), and the substances on the right - hand side are products (they are formed in the chemical reaction).

1. For \(2H_2 + O_2

ightarrow2H_2O\), \(2H_2+O_2\) are on the left - hand side of the arrow, so they are reactants.

1. For \(2H_2 + O_2

ightarrow2H_2O\), \(2H_2O\) is on the right - hand side of the arrow, so it is a product.

1. For \(C_6H_{12}O_6 + 6O_2

ightarrow6CO_2 + 6H_2O\), \(6CO_2 + 6H_2O\) is on the right - hand side of the arrow, so it is a product.

1. For \(C_6H_{12}O_6 + 6O_2

ightarrow6CO_2 + 6H_2O\), \(C_6H_{12}O_6+6O_2\) are on the left - hand side of the arrow, so they are reactants.

1. Reactants are the elements or compounds that enter into a chemical reaction.
2. Products are the substance(s) formed in a chemical reaction.

Answer:

1. reactants
2. products
3. products
4. reactants
5. reactants
6. products
