Explanation / Answer
1. Particulate level :
One molecule of Br2 reacts with one molecule of Cl2 to produce 2molecules of BrCl
Molar level :
One mole of Br2 reacts with one mole of Cl2 to produce 2 moles of BrCl
2. One mole of silicon tetra flouride reacts with two moles of water to produce four moles of hydroflouric acid and one mole of silicon dioxide.
3. Particulate level:
One molecule of CO reacts with one molecule of Cl2 to produce one molecule of COCl2
Molar level :
One mole of CO reacts with one mole of Cl2 to produce one mole od COCl.
Note: coefficients of reactants or products in a stoichiometric equation always represent the no. Of atoms if the substance is atomic in nature, no. Of molecules if the substance is molecular in nature and it always represents the no. Of moles of atoms or molecules with respect to the nature of the substance (reactants / products)
