Question

What is M in this Q??? ​

Answer 1

Answer:

here is the answer to this question

Explanation:

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

To write the chemical formula of any compound the simplest method is the

criss-cross method.

In this method

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

Step 2: First we should know the component of a compound that is 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 the halogen family.

Step 4: Now we have to criss-cross.

We get MgSO4

Answer 2

Answer:

Solid State M-2-MeO-CP compounds, where M stands for bivalent metals (Mn, Fe, Co, Ni, Cu and Zn) and 2-MeO-CP is 2-methoxycinnamylidenepyruvate, were synthesized. ... In both atmospheres (CO2, N2) the thermal decomposition occurs in consecutive steps which are characteristic of each compound.
