Question

identify the reactants in the chemical equation.
2h₂ + o₂ → 2h₂o
2 h₂ + o₂
2 h₂o
there are no reactants in the chemical equation.
o₂ only

Explanation:

Step1: Recall the definition of reactants

In a chemical equation, reactants are the substances that undergo a chemical change. They are located on the left - hand side of the arrow.

Step2: Analyze the given chemical equation

In the equation \(2H_2+O_2
ightarrow2H_2O\), the substances on the left - hand side of the arrow (\(
ightarrow\)) are \(2H_2\) and \(O_2\). Their combination is written as \(2H_2 + O_2\).

Answer:

\(2H_2+O_2\) (the first option)
