Question

a metal M forms an oxide of the formula MO2. write the formula of chloride and phosphate of m
​

Answer 1

The corresponding chloride would be MCl4. But as a practical matter, can be more complex. For example, manganese dioxide treated with hydrochloric acid forms MnCl2 and chlorine because of the instability of the tetravalent chloride. A similar situation exists for lead chloride. In some cases an oxychloride MOCl2) can form, depending on the amount of excess acid.

Answer 2

Answer:

.${InM2O3 valency of metal M^+3}$

so the formula of metal nitride will be

${M_3N_3⇒MN}$
