Concept explainers
(a)
Interpretation:
The given equation has to be balanced.
Concept Introduction:
Balanced equation is a representation of a
Steps in balancing the information
- Step 1: Write the unbalanced equation
- Step 2: Find the coeffienct to balance the equation.
- The coeffienct should be reduced to the smallest whole number
(b)
Interpretation:
Number of moles of carbon needed to react with
Concept Introduction:
Molecular weight is the sum of weights of all the atoms in a molecule.
One mole of any substance is the amount whose mass in grams is numerically equal to the substances atomic or weight. One mole contains
Number of moles can be calculated by using the below equation,
(c)
Interpretation:
Mass of carbon needed to react with
Concept introduction:
Molecular weight is the sum of weights of all the atoms in a molecule.
One mole of any substance is the amount whose mass in grams is numerically equal to the substances atomic or weight. One mole contains Avogadro’s number of atoms
Mass can be calculated by using the below equation,
