Question

explain how to a chemical reaction can be standers chemical equation​

Answer 1

Answer:

Chemical reactions are represented on paper by chemical equations. For example, hydrogen gas (H2) can react (burn) with oxygen gas (O2) to form water (H2O). The chemical equation for this reaction is written as:

2H2+O2→2H2O

Answer 2

Answer:

According to the law of conservation of mass, when a chemical reaction occurs, the mass of the products should be equal to the mass of the reactants. Therefore, the amount of the atoms in each element does not change in the chemical reaction. The reactants side is equal to the number of atoms in the products side.

Examples:

Reactants →Product

2H2 + O2 → 2H2O

N2 + H → NH3
