Detailed Explanation:
1) Rusting of Iron
4Fe + 3O2 + 2H2O -> 2Fe2O32H2O
Reactants :-
Fe = 4
O = 3 * 2 + 2 = 8
H = 2 * 2 = 4
Products :-
Fe = 2 * 2 = 4
O = 2 * 3 + 2 = 8
H = 2 * 2 = 4
2) Fermentation of sucrose…
C12H22O11 + H2O -> 4C2H5OH + 4CO2
Reactants :-
C = 12
H = 22 + 2 = 24
O = 11 + 1 = 12
Products :-
C = 4 * 2 + 4 = 12
H = 4 * 5 + 4 = 24
O = 4 * 2 + 4 = 12
Looking closely at the way I have taken the total number of elements on the reactants and products side, you can solve the rest.

Answer: False
When the diaphragm
contracts, the muscles will also contract and pull upward and increase the size
of the thoracic cavity thus decreases air pressure inside during inspiration. After
the diaphragm contracts, it goes to relaxation, the muscles will also relaxed. It
gets looser and return to its original position higher up in the chest. This increase
the pressure in the chest, which force the air in the lungs out through the
nose.
