Using appropriate chemical reactions for illustration, show how calcium present as the dissolved bicarbonate salt in water is easier to remove than other forms of hardness such dissolved Calcium chloride

Explanation:

Calcium bicarbonate  dissolved in hard water can easily be removed by heating the hard water . On heating , it decomposes to give calcium carbonate which is insoluble and therefore can be filtered out .

Ca( HCO₃)₂  =  CaCO₃ + CO₂ + H₂O.

In this way hardness of water is removed .

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.
