Question

M is bivalent metal. Write down the steps to find the find the chemical formulae of its compounds formed with the radicals ,sulphate and phosphate

Answer 1

Answer:

MgSO4

Explanation:

M is bivalent metal means it has valency 2. Beryllium, Magnesium, Calcium,Scandium, Barium, Radium are metals having valency 2.

To write chemical formula of any compound the simplest method is criss cross method.

In this method

Step 1: we will take Magnesium to form compound with sulphate.

Step 2: First we should know the component of compound that are magnesium and sulphur. Step 3: Now we have to write the valency of both components that is of magnesium 2 as it is bivalent and of sulphur is 2 as it belongs to halogen family.

Step 4: Now we have to criss cross.

We get MgSO4
