The combstion of ZnS in excess oxygen gives ZnO and SO₂ as the products.
hence the equation should be;
ZnS(s) + O₂(g) →ZnO(s) + SO₂(g)
At the left hand side: At the right hand side:
number of Zn atoms = 1 number of Zn atoms = 1
number of S atoms = 1 number of S atoms = 1
number of O atoms = 2 number of O atoms = 3
Hence the balanced equation is;
2ZnS(s) + 3O₂(g) →2ZnO(s) + 2SO₂(g)
Answer:
936g/mol
Explanation:
To find the molar mass of a molecule, you find the sum of the molar masses of each atom in the molecule.
This compound has 40 carbon atoms, 60 Hydrogen atoms, 10 Nitrogen atoms, 12 Oxygen atoms, and 2 Sulphur atoms.
The molar mass of:
- Carbon is 12g/mol
- Hydrogen is 1g/mol
- Nitrogen is 14g/mol
- Oxygen is 16g/mol
- Sulphur is 32g/mol

Hope this somehow helped.
Molecule is the general term used to describe any atoms that are connected by chemical bonds.
Every combination of atoms is a molecule. A compound is a molecule made
of atoms from different elements.
Well, if a molecule is considered to be a discrete small unit made up of atoms joined
together, then NaCl, and any other ionic solid is not really a molecule. In NaCl we have a
repetitive crystal structure in which each Na+ ion is surrounded by Cl-
ions, and vice-versa, for as far as the crystal extends. There really isn't such a thing
as an NaCl molecule.
