Question

balance the chemical equation​

Answer 1

$\bf \underline{Answer:-}$

$\sf \: a)\:\: Potassium \: \: bromide (aq) + Barium \: \: iodide (aq) \implies \: \: Potassium iodide (aq) + Barium \: \: bromide (s)$

Balanced Equation,

$\sf \: 2KBr (aq) + BaI_2(aq) \implies 2KI (aq) + BaBr_2 (s)$

•°• It is a double displacement reaction

$\sf \: b) Zinc \:\: Carbonate (s) \implies Zinc\:\: oxide (s) + Carbcon\:\: dioxide (g)$

Balanced Equation,

$\sf \: ZnCO_3(s) \implies ZnO (s) +CO_2(g)$

•°• It is a decomposition reaction
