Ba(OH)2 can be neutralized by adding an acid to the solution. We can add HCl to produce:
Ba(OH)2 + 2HCl ===> BaCl2 + 2H2O ; producing a salt BaCl2 and water.
or we can add H2SO4 to produce:
Ba(OH)2 + H2SO4 ===> BaSO4 + 2H2O; producing a salt, BaSO4, and water. <span />

Answer:
CaBr2 is a colorless solid and the charge on Calcium is +2
Explanation:
CaBr2 is a colorless solid at room temperature.
Other properties include -
a) It is a crystalline solid
b) Melting point of 765°C.
c) It is deliquescent
d) Soluble in water and absolute alcohol.
The charge of Br is -1. Here two atoms of Br attaches with one atom of calcium. Hence the charge of calcium is +2
True, to convert from moles to atoms, multiply the molar amount by Avogadro's number. To convert from atoms to moles, divide the atom amount by Avogadro's number (or multiply by its reciprocal).
