Hint:In a balanced chemical equation the number of atoms of each chemical compound taking part in the chemical reaction is the same on both sides of the chemical equation. The reaction between the metal and base gives salt as a main product with releases of hydrogen gas.
Complete step by step answer:
The chemical reaction is defined as a reaction taking place between the reactant to form new products in the presence of different chemical conditions like temperature, pressure, solvent reagents.
A chemical equation is defined as the representation of chemical reaction in terms of symbols and formulas of the chemical compound. In the chemical equation, the reactant compounds are placed at the left hand side of the reaction and product compounds are placed at the right hand side of the reaction.
The chemical reaction between zinc and potassium hydroxide solution is shown below.
$Zn(s) + KOH(aq) \to {K_2}Zn{O_2}(aq) + {H_2}(g)$
In this reaction, zinc reacts with potassium hydroxide solution to form potassium zincate and hydrogen gas.
The balanced chemical equation is defined as the chemical equation where the number of moles of reactant present in the left side of the reaction is equal to the number of moles of product in the right side of reaction.
The balanced chemical reaction between zinc and potassium hydroxide solution is shown below.
\[Zn(s) + 2KOH(aq) \to {K_2}Zn{O_2}(aq) + {H_2}(g)\]
In this reaction, one mole of zinc reacts with a mole of potassium hydroxide solution to form one mole of potassium zincate and one mole of hydrogen gas.
Note:
The balanced chemical equation follows the law of conservation of mass which states that the mass cannot be created nor be destroyed; it can only be exchanged from one form to another. The reaction between zinc and potassium hydroxide is an exothermic reaction as heat is released.
