<h2>Let us solve for it </h2>
Explanation:
Magnesium oxide
- It is MgO
- Its molecular mass is : 24 +16=40 g
- When MgO decomposes it forms = 3.54 g of oxygen gas
- when 40 g of MgO decomposes it forms = 16g of oxygen
- or we can say that :
- 16g of oxygen is produced when 40 g of MgO is decomposed .
- 1g of oxygen will be formed from =40/16g of MgO
- 3.54 g of oxygen will be formed = 40/16 x 3.54 =8.85g of MgO

It has: 2 atoms of sodium (Na) 1 atom of Carbon 3 atoms of Oxygen bound together with ionic and polar-covalent bonds
See , from the equation we can see that for forming two mole of H2O 2Mole of H2 has to react.
Mass of 2 Mole H2O is 18*2gm or 36gm.
So for forming 36 gm H2O 2×2 I.e. 4 gm H2 has to take part in reaction.
Therefore, to form 1 gm H2O 4÷36 gm of H2 has to take part.
So, for forming 47gm H2O (4÷36)×47 gm H2 has to take part
I.e. 5.22 gm of H2 has to take part
So, ans is 5.22 gm of hydrogen.
Hope it helps!!!
Calcium chloride forms an ionic compound with a
regularly arranged lattice of oppositely charged ions.
The Na+ and Cl- ions are held together by
strong electrostatic forces.
