2HBr+CaCO3=CaBr2 +CO2+H2O
When mercurous carbonate reacts with calcium bromide, a double displacement reaction occurs, resulting in the formation of mercurous bromide and calcium carbonate. The balanced chemical equation for this reaction is: Hg2CO3 + CaBr2 -> Hg2Br2 + CaCO3.
When mercurous carbonate (Hg2CO3) reacts with calcium bromide (CaBr2), it forms mercurous bromide (Hg2Br2) and calcium carbonate (CaCO3). This is a double displacement reaction where the positive ions in the compounds switch places to form the products.
The balanced chemical equation for the reaction between calcium carbonate (CaCO3) and hydrogen (H2) to form calcium oxide (CaO) is: CaCO3 + H2 -> CaO + CO2
When calcium hydrogen carbonate reacts with hydrochloric acid, it forms calcium chloride, carbon dioxide gas, and water. The balanced chemical equation for the reaction is Ca(HCO3)2 + 2HCl -> CaCl2 + 2CO2 + 2H2O.
Hydrogen and hydroxyl are spectator ions.
When mercurous carbonate reacts with calcium bromide, a double displacement reaction occurs, resulting in the formation of mercurous bromide and calcium carbonate. The balanced chemical equation for this reaction is: Hg2CO3 + CaBr2 -> Hg2Br2 + CaCO3.
When calcium bromide reacts with sodium carbonate, a double displacement reaction occurs. Calcium carbonate and sodium bromide are formed as the products. The balanced chemical equation for this reaction is CaBr2 + Na2CO3 -> CaCO3 + 2NaBr.
There is no direct chemical reaction between calcium carbonate and hydrogen peroxide. Calcium carbonate is a stable compound and does not readily react with hydrogen peroxide under normal conditions.

When calcium carbonate (CaCO₃) reacts with hydrogen peroxide (H₂O₂), a decomposition reaction can occur, particularly in the presence of an acid. The hydrogen peroxide may release oxygen gas (O₂) as it decomposes, while the calcium carbonate may react with any acid present to produce calcium salts, water, and carbon dioxide (CO₂) gas. Overall, the reaction can produce effervescence due to the release of CO₂ and O₂. However, under normal conditions, the direct reaction between just calcium carbonate and hydrogen peroxide is not significant.
When calcium hydrogen carbonate reacts with hydrochloric acid, it forms calcium chloride, carbon dioxide gas, and water. The balanced chemical equation for the reaction is Ca(HCO3)2 + 2HCl -> CaCl2 + 2CO2 + 2H2O.
The reaction between sodium bromide and calcium hydroxide is a double displacement or metathesis reaction. In this reaction, the sodium and calcium ions switch partners to form sodium hydroxide and calcium bromide.
Hydrogen and hydroxyl are spectator ions.
Calcium hydrogen carbonate is composed of calcium ions (Ca^2+), hydrogen carbonate ions (HCO3^-), and water molecules (H2O). When dissolved in water, calcium hydrogen carbonate dissociates to form these ions.
The equivalent weight of calcium carbonate can be calculated by dividing its molecular weight by the number of acidic hydrogen ions that it can donate in a reaction. In the case of calcium carbonate, it can donate two moles of hydrogen ions, so the equivalent weight would be its molecular weight divided by 2.
The hydrogen carbonate solution would turn cloudy white due to the formation of calcium carbonate precipitate as a result of the reaction between hydrogen carbonate and calcium ions in the snails' shells.
