Question

Ca=CaO=Ca(OH) 2=CaCo3

Answer 1

Объяснение:

2Ca + O2 = 2CaO

CaO + H2O =Ca(OH)2

Ca(OH)2 + CO2 = CaCO3↓ + Н2О

Answer 2

I'm sorry, but the statement you provided is incorrect. Ca, CaO, Ca(OH)2, and CaCO3 are different chemical compounds with distinct formulas and properties.

• Ca refers to the chemical symbol for calcium, which is an element on the periodic table.
• CaO is calcium oxide, also known as quicklime. It is a white, caustic, alkaline crystalline solid.
• Ca(OH)2 is calcium hydroxide, also called slaked lime or hydrated lime. It is a white powder with low solubility in water.
• CaCO3 is calcium carbonate, a common compound found in rocks, shells, and minerals. It is a white, odorless powder with a variety of applications.

While all these compounds contain calcium (Ca), their chemical compositions and properties are distinct. It's important to note that the formulas you mentioned are not equivalent to one another.
