Interpret the equations in terms of particles moles and mass
a. 2PbS +3O2 = 2PbO +2SO2
b. 4HCl +O2 = 2H2O + 2Cl2

The equations in terms of particles moles and mass

a. 2PbS +3O2 = 2PbO +2SO2

b. 4HCl +O2 = 2H2O + 2Cl2

a) 2 Molecules of Pbs + 3 molecules of O2 = 2 Molecules of PbO + 2 molecules of SO2

2 Moles of PbS + 3 Moles of O2 = 2 moles of PbO + 2 Moles of SO2

478.6 grams of PbS+ 48 grams of 02 = 446.4 grams +  128 grams SO2

b). 4 molecules of HCl + 1 molecule of oxygen = 2 molecules of water +2 molecules pf Cl2

4 mole of HCl + 1 mole of oxygen = 2 mole of water + 2 moles of Cl2

146.4 grams of HCl + 31.8 grams = 36 grams of H20 + 159.8 grams of Cl2.

Explanation:

Calculation of:

particles =?

moles =?

mass =?

Equation given:

a) 2PbS +3O2 = 2PbO +2SO2

2 Molecules of Pbs + 3 molecules of O2 = 2 Molecules of PbO + 2 molecules of SO2

2 Moles of PbS + 3 Moles of O2 = 2 moles of PbO + 2 Moles of SO2

Mass of the reactant and product is calculated as:

number of moles x atomic mass

so,

atomic mass of PbS =239.3 grams/mole

mass = 2 x 239.3

          = 478.6 grams

atomic mass of O2 = 16 grams/mole

mass = 3 x 16

         = 48 grams

atomic mass of PbO = 223.2 grams/mole

mass = 2 x 223.2

         = 446.4 grams

atomic mass of SO2 = 64 grams/mole

mass = 2 x 64

          = 128 grams

b)  Calculation of:

particles =?

moles =?

mass =?

Equation given:

4HCl +O2 = 2H2O + 2Cl2

4 molecules of HCl + 1 molecule of oxygen = 2 molecules of water +2 molecules pf Cl2

4 mole of HCl + 1 mole of oxygen = 2 mole of water + 2 moles of Cl2

To calculate mass, formula used is

mass = number of moles x atomic mass

atomic mass of HCl =36.46 gram/mole

mass = 4 x 36.46 = 146.4 grams

atomic mass of oxygen

mass = 2x 15.9 = 31.8 grams

atomic mass of water = 18 grams,mole

mass = 2 x 18 = 36 grams

atomic mass of Cl2 = 79.90 grams/mole

mass = 2 x 79.90 = 159.8 grams
