Question

calcium carbonate + water carbondioxide gives calciumm bicarbonate

Answer 1

Answer:

In the reverse process, dissolved carbon dioxide (CO2) in rainwater (H2O) reacts with limestone calcium carbonate (CaCO3) to form soluble calcium bicarbonate (Ca(HCO3)2). This soluble compound is then washed away with the rainwater. This form of weathering is called carbonation.

Chemical formula: Ca(HCO3)2

Solubility in water: 16.1 g/100 mL (0 °C); 16.6 ...

Other cations: Magnesium bicarbonate

Main hazards: Irritant

Explanation:

Answer 2

Answer:CaCO3( s ) → CaO( s ) + CO2( g ) Calcium carbonate will react with water that is saturated with carbon dioxide to form the soluble calcium bicarbonate. This reaction is important in the erosion of carbonate rock, forming caverns, and leads to hard water in many regions.
