How many atoms are found in the products of the following chemical equation?
coldgirl [10]

There are 13 atoms in the product

<h3>Further explanation</h3>

Given

Reaction

H2SO4 + 2KOH --> K2SO4 + 2H2O

Required

The number of atoms

Solution

In a chemical equation, there are reactants on the left and products on the right

Reactants : H2SO4 + 2KOH

Products : K2SO4 + 2H2O

The number of atoms is determined by their reaction coefficient and the subscript of the atoms in the compound

K2SO4 (coefficient = 1) :

K = 2 atoms

S = 1 atom

O = 4 atoms

Total atoms = 7 atoms

2H2O(coefficient = 2) :

H = 2 x 2 = 4 atoms

O = 2 x 1 = 2 atoms

Total atoms = 6 atoms

Total = 13 atoms

Answer: 0.714 moles of PbI_2 will be produced from 237.1 g of potassium iodide

Explanation:

To calculate the moles :

\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}    

\text{Moles of potassium iodide}=\frac{237.1g}{166g/mol}=1.428moles

The balanced chemical reaction is:

Pb(NO_3)_2+2KI\rightarrow PbI_2+2KNO_3

According to stoichiometry :

2 moles of KI produce =  1 mole of PbI_2

Thus moles of KI will require=\frac{1}{2}\times 1.428=0.714moles  of PbI_2

Thus 0.714 moles of PbI_2 will be produced from 237.1 g of potassium iodide
