They do not react, the Calcium cannot displace the Potassium as it is less reactive.
Ca + Br2 = CaBr2 doesn't need to be balanced.
HC2H3O2(aq) + KOH(aq) -> H2O(l) + KC2H3O2(aq)It's already balanced, since there are two acetates, two Hydrogens on each side, and 1 oxygen on both sides :)
You have answered the question for yourself. Calcium + Chlorine = Calcium chloride. The BALANCED reaction equation is Ca(s) + Cl2(g) = CaCl2(s)
No, they don't react with each other in aqueous solution and on heating nitrate becomes decomposed.
Carbon dioxide and water. 2HNO3(aq) + CaCO3(s) => Ca(NO3)2 (aq) + H2O + CO2
What is $169.00 plus tax in Northern California?
The aba-ca-by =2
2Ca + 3O2 + 2C -> 2CaCO3
NaOH KOH Ca(OH)2
It is already balanced
Ca + Br2 = CaBr2 doesn't need to be balanced.
The balanced equation is Ca(OH)2 + H2SO4 → CaSO4 + 2H2O.
Calcium and water react to form calcium hydroxide and hydrogen. Ca + 2H2O --> Ca(OH)2 + H2
HC2H3O2(aq) + KOH(aq) -> H2O(l) + KC2H3O2(aq)It's already balanced, since there are two acetates, two Hydrogens on each side, and 1 oxygen on both sides :)
