Question

what is a chemical equation with 10 examples
​

Answer 1

Explanation:

A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and formulae, wherein the reactant entities are given on the left-hand side and the product entities on the right-hand side.

Representation of a chemical reaction in terms of symbols and chemical formula of the reactants and products taking part in the reaction is known as a chemical equation. For example, NH3+HCl→NH4Cl, in this reaction ammonia and hydrochloric acid is reacting to form ammonium chloride.

Answer 2

Explanation:

A chemical equation is a symbolic representation of chemical reaction in the form o symbols and formulae where in the reactant entities are given on the left hand side and the product entities on right hand side.

Eg. CaCO 3(s)→CaO(s)+CO 2 (g)

2Mg(s) + O2(g) △→ 2MgO(s)

Zn(s) + H2SO4(aq) → ZnSO4(aq) + H2(g) ↑

BaCl2(aq) + H2SO4(aq) → BaSO4(s) (ppt) + 2HCl(aq)

H2 + O2 → H2O

3Fe + 4H2O → Fe3O4 + 4H2.

CaCO3(s) heat−→− CaO(s) + CO2(g)

2Fe(OH)3(s) △→ Fe2O3(s) + 3H2O(l)

2Pb(NO3)2(s) heat−→− 2PbO(s) + 4NO2(g) + O2(g)

NaOH(aq) + HCl(aq) → NaCl(aq) + H2O(l)
