Question

co₂(g) + casio₃(s) + h₂o(l) → sio₂(s) + ca(hco₃)₂(aq)
express your answer as a chemical equation including phases.
a chemical reaction does not occur for this question.

Explanation:

Step1: Identify reactants and products

The reactants are carbon - dioxide gas ($CO_2(g)$), calcium silicate solid ($CaSiO_3(s)$) and liquid water ($H_2O(l)$). The products are silicon dioxide solid ($SiO_2(s)$) and aqueous calcium bicarbonate ($Ca(HCO_3)_2(aq)$).

Step2: Write the balanced chemical equation

The given equation $CO_2(g)+CaSiO_3(s)+H_2O(l)
ightarrow SiO_2(s)+Ca(HCO_3)_2(aq)$ is already balanced.

Answer:

$CO_2(g)+CaSiO_3(s)+H_2O(l)
ightarrow SiO_2(s)+Ca(HCO_3)_2(aq)$
