answer correctly and no spamming​

Answer 1

Explanation:

$\huge\fbox\pink{A}\fbox\blue{n}\fbox\purple{S}\fbox\green{w}\fbox\red{E}\fbox\orange{r}$

${\bold{\sf{a) \: \: \: {Cr}^{3+} \: + \: {F}^{-}}}}$

${\bold{\sf{⟼ \: \: CrF_3}}}$

NOTE :

➠ Lead is a metal, it can't be negative electrovalent.

➠ The reaction is wrong. The Real Reaction is this :

${\bold{\sf{b) \: \: \: {Pb}^{2+} + {(PO_4)}^{3-}}}}$

${\bold{\sf{⟼ \: \: \: Pb_3(PO_4)_2}}}$

Answer 2

Answer:

(a) cr³+f- will form crF3.

(b)pb²- + (po4)³- will form pb3 (po4)2
