Ответ:
Na₂SO₄ + BaCl₂ > 2NaCl + BaSO₄
stoichiometry of Na₂SO₄ to BaCl₂ is 1:1
first we need to find out which the limiting reactant is
limiting reactant is fully used up in the reaction.
number of Na2So4 moles - 0.5 mol number of BaCl2 moles - 60 g / 208 g/mol = 0.288 mol
since molar ratio is 1:1 equal number of moles of both reactants should react with each other
therefore BaCl2 is the limiting reactant and Na2SO4 is in excess. amount of product formed depends on number of limiting reactant present.
stoichiometry of BaCl₂ to BaSO₄ is 1:1.
therefore number of BaSO4 moles formed - 0.288 mol
Ответ:
0.29
Explanation:
To calculate the moles, we use the equation:
Putting values in above equation, we get:
Moles of = 0.5 moles
According to stochiometry, 1 mole of reacts with 1 mole of
Thus 0.29 moles of will react with 0.29 moles of
Thus is the limiting reagent as it limits the formation of products and is the excess reagent.
1 mole of produces = 1 mole of
0.29 moles of will produce= 0.29 moles of
