Concept explainers
(a)
Interpretation:
The balanced equation for the reaction and the limiting reagent of the reaction has to be identified.
Concept introduction:
Balanced reaction is a
Steps in balancing the information
- Step 1: Write the unbalanced equation
- Step 2: Find the coefficient to balance the equation.
- The coefficient should be reduced to the smallest whole number
Limiting reagent:
In a chemical reaction, the substance which is totally consumed at the end of the reaction is known as limiting reaction. Without the particular atom or element the reaction cannot be procced further or the product becomes limited.
(b)
Interpretation:
The number of moles in a gram for the substance has to be calculated.
Concept introduction:
Number of moles:
One mole is the equal to number of atoms in
Number of moles =
