Question

a metal carbonate on heating is converted to metal oxide and is reduced to 60% of its original weight. the equivalent weight of the metal is​

Answer 1

Answer:

Then, the equivalent weight of the carbonate part of metal carbonate is 602=30g. The equivalent weight of metal is the difference in the equivalent weight of MCO3 and the equivalent weight of CO3−. The equivalent weight of metal whose 1 gram carbonate on heating gives 0.6 gram of metal oxide, is 25g

Answer 2

Answer:

25 is the answer hope it helps

Explanation:

Let the metal is M, its mass is 1 g

MCO

3

→MO+CO

↑

mass of metal oxide formed =1×0.6=0.6g

x+60

=

x+16

0.6

x+16=0.6x+36

x−0.6x=36−16=20

0.4x=20

x=
