Question

what is the molecular equation for sodium chromate and calcium nitrate

Answer 1

does anyone know?

Answer 2

hint:
a) for sodium chromate:
the oxidation state of Sodium \(\large Na^+\) is \(+1\), whereas the oxidation state of chromate ion is: \(\large CrO_4^{2-}\) is \(-2\)

b) cor calcium nitrate:
the oxidation state of Calcium \(\large Ca^{2+}\) is \(+2\), whereas the oxidation state of nitrate ion \(\large NO_3^-\) is \(-1\)
