Ca+2 Br-1 -----> these are the ions and their charges
Ca+2 Br-1 Br-1 ------> the charges have to add up to zero, so one -1 Br ion is added to cancel out the +2 Ca.
CaBr2 -----> simplify
have any reaction between calcium carbonate & milk
Br2 + CaI2 → CaBr2 + I2
calcium + copper sulphate = calcium sulphate + copper hydroxide
There is not a reaction as such - the hydrated salt is fomed. Calcium Sulfate is not very soluble in water.
No, the chemical properties of calcium and bromine are not similar. The melting point for Calcium is 8390C, bromine's is -7.250C. Calcium's boiling point is 1484°C, bromine's is 58.750C. etc. Calcium is a silvery white, soft alkaline earth metal. Although none of the alkaline earths occur free in nature, calcium compounds are abundant. Bromine is a reddish-brown liquid, and it has a metallic luster in solid form.
CaBr2
Calcium hydroxide, a base, will reaction with phenol, a weak acid in a neutralization reaction to give a salt (calcium phenoxide (Ca(PhO-)2) and water.
Yes it is a chemical reaction between the calcium and the oxygen [i may be wrong their] but the rate of reaction is very slow.

Calcium react with bromine forming calcium bromide.
This chemical reaction is: CaO + H2O = Ca(OH)2.
There is no chemical reaction between water and calcium hydroxide. They simply form a mixtures commonly called limewater.
