The formula of chloride of a metal M is MCL 2 write the formula of its
sulphate
zincate
hydroxide
Answers
Answer:
The formula of a metal is MCl2 => valency of M is 2+
Therefore formula of its sulphate is MSO 4. (Valency of SO 4 is 2-)
Its Zincate is MZnO 2. (Valency of ZnO 2 is 2-)
It's hydroxide it M(OH) 2. (Valency of OH is 1-)
It's that simple really....
Hope this helped!

MSO4 (Sulphate), MZnO2 (ZINCATE) M(OH)2 ( HYDROXIDE)
Explanation:
The formula MCl2 shows that one atom of metal M reacted with 2 atoms of Cl
Thus M has valency of +2
Formula for the sulphate will be
MSO4
since metal M has +2 valency
Sulphate has SO4^2- valency
Formula for zincate will be
MZnO2 as zincate has valency of -2.
Zincate is Zn(OH)4^2-
Formula for hydroxide wiil be
M(OH)2
Because magnesium has +2 valency and hydroxide has one minus as OH-
