Question

Rewrite the equation below using the correct conventions for stoichiometric coefficients. 2 BaCl2 + 2 H2SO4 → 2 BaSO4 + 4 HCl

Answer 1

`BaCl2+H2SO4 \rightarrow BaSO4+2HCl`

Step-by-step explanation:

The given equation is:

`2 BaCl2+2H2SO4 \rightarrow2BaSO4+4HCl`

Based on the reaction stoichiometry:

2 moles of barium chloride (BaCl2) reacts with 2 moles of sulfuric acid (H2SO4) to form 2 moles of barium sulfate (BaSO4) and 4 moles of HCl

Although the reaction is balanced, the correct convention is to depict reactions in terms of the lowest molar ratio. Therefore the coefficients (2,2,4 and 4) can be divided by 2 to give:

`BaCl2+H2SO4 \rightarrow BaSO4+2HCl`
