Concept explainers
Interpretation :
The reason for the water formation reaction from hydrogen and oxygen to not be balanced must be explained. A picture of the balanced equation must be drawn.
Concept Introduction :
2 moles of hydrogen reacts with 1 mole of oxygen to produce 2 moles of water.
Answer to Problem 34A
The reaction is not balanced as there are 2 O and 2 H atoms in the reactant side whereas in product side there are 2 H and 1 O atom.
A picture of the balanced equation is drawn.
Explanation of Solution
In the unbalanced equation the number of oxygen was not the same in both the sides of the equation. To balance it 2 moles of hydrogen are taken and 2 moles of water is produced.
As shown in the picture 2 moles hydrogen has reacted with 1 mole of oxygen to produce 2 moles of water.
