Question

$CaO$ is basic based on following reaction:
$6CaO+P_4{O}_{10}\to 2C{a}_3(P{O}_4{)}_2$
If true enter 1, else enter 0.

Answer 1

CaO reacts with acid to give salt and so, it is a basic oxide.
$6CaO+P_4{O}_{10}\to 2C{a}_3(P{O}_4{)}_2$
(OR)
Basic oxides are the oxides of metals. If soluble in water, they react with water to produce hydroxides (alkalies).
So, the statement is true.
