2 Ca + 2O2 = 2(CaO2)
Ca + Br2 = CaBr2 doesn't need to be balanced.
No, CaO is an ionic compound. It is composed of calcium (Ca) and oxygen (O) ions that are held together by ionic bonds.
The balanced chemical equation is Ca(OH)2 + Na2CO3 + 2HNO3 → Ca(NO3)2 + 2NaOH + CO2 + H2O
You have answered the question for yourself. Calcium + Chlorine = Calcium chloride. The BALANCED reaction equation is Ca(s) + Cl2(g) = CaCl2(s)
They do not react, the Calcium cannot displace the Potassium as it is less reactive.
It is already balanced
Ca + Br2 = CaBr2 doesn't need to be balanced.
The balanced equation is Ca(OH)2 + H2SO4 → CaSO4 + 2H2O.
Ca + Cl2 ---> CaCl2

2Ca + 3O2 + 2C -> 2CaCO3
No, CaO is an ionic compound. It is composed of calcium (Ca) and oxygen (O) ions that are held together by ionic bonds.
The balanced chemical equation is Ca(OH)2 + Na2CO3 + 2HNO3 → Ca(NO3)2 + 2NaOH + CO2 + H2O
Calcium and water react to form calcium hydroxide and hydrogen. Ca + 2H2O --> Ca(OH)2 + H2
(Don't forget to balance it) The precipitate here has to be 2NaCl, as Ca(CO3)2 technically dissolves.
