Question

1. true or false: there are more hydrogen atoms in the product than in the reactant. 2h₂ + o₂ → 2h₂o

Explanation:

Step1: Count hydrogen atoms in reactants

In the reactant side of the equation $2H_2 + O_2
ightarrow2H_2O$, the number of hydrogen - atom in $2H_2$ is $2\times2 = 4$ (since each $H_2$ molecule has 2 hydrogen atoms).

Step2: Count hydrogen atoms in products

In the product side, in $2H_2O$, the number of hydrogen atoms is $2\times2=4$ (as each $H_2O$ molecule has 2 hydrogen atoms).

Step3: Compare the number of hydrogen atoms

The number of hydrogen atoms in the reactants is equal to the number of hydrogen atoms in the products.

Answer:

False
