(d) BaCl, +H, SOBaSO, + HCI
Answers
Answer:
(a) 2HNO3+Ca(OH)2= Ca(NO3)2+2H2O
(b) 2NaOH + H2SO4 → Na2SO4 + 2H2O()
(c) Already balanced equation
(d) BaCl2 + H2SO4 → BaSO4 + 2HCl
Answer:
The representation of a chemical reaction in the form of substances is known as a chemical equation. The equation in which the number of atoms of all the molecules is equal on both sides of the equation is known as a balanced chemical equation.
(a) 2HNO3 + Ca(OH)2 → Ca(NO3)2 + 2H2O
(b) 2NaOH + (H2SO4) → Na2SO4 + 2H2O
(c) NaCl + AgNO3 → AgCl + NaNO3
(d) BaCl2 + H2SO4 → BaSO4 + 2HCl
