The reaction is:
CaCO3 + H2SO4 = CaSO4 + H2O + CO2
800 mg
They react to give calcium sulfate and water, though the reaction is not very fast because the calcium sulfate is poorly soluble. We sometimes use an equals sign instead of an arrow in a chemical equation but we read it as 'gives' rather than 'equals', because we are not saying the substances are the same thing.
425 g calcium (Ca) is equal to 10,604 moles.
9 g calcium is equal to 0,224 moles.
29,0 g of calcium is equal to 0,723 moles.
Carbon dioxide, water, and magnesium sulfate
It equals calcim carbonate and it must be very reactive I thInk .
hg2co3 + ca(br)2 equal to caco3 + hg2(br)2
The lake's PH becomes lower or neutral(equal).
Marble is mainly CaCO3 so its one mole is equal to 100 g.

Endothermic because thermal decomposition is the breakdown of a compound using heat. Remember endo means more energy is taken in breaking the bonds of copper carbonate than there is given out when making the bonds of copper oxide and carbon dioxide.
9 g calcium is equal to 0,224 moles.
425 g calcium (Ca) is equal to 10,604 moles.
Carbon dioxide gas and a salt
29,0 g of calcium is equal to 0,723 moles.
