4H+o2 = 2H2O.

4+16x2 = 2x18.

1+8 = 9.

Answer is 9 kg of water.

I do not understand this explnation.

4H + O2 = 2H2O.

4 + 16 x 2 = 2 x1 8.

1 (i.e. 1 Kg of hydrogen) +8 (i.e. 8 Kg of Oxygen) = 9 kg of water.

4H + O2 = 2H2O.
4 (1) + 16 * 2 = 2 * 1* 2 * 16.

We can take 4 common so final answer is 1 + 8 = 9.

We cannot write 4H.
2h2+o2 = 2h2O.
4(1)+32 = 36,
= 9kg.

H2 + O = H2 0.
1X2 + 16 = 1X2 + 16,
2 + 16 = 18.

1KG EQUALS
2/2 + 16/2 = 18/2,
1 + 8 = 9.
ie. 9kg of water.
