Question

What amount of moles of of BaSO4 can be obtained on mixing 0.5 moles BaCl2 with 1 mole of H2SO4

Answer 1

hope this helps any doubt please comment

Answer 2

Answer : The amount of moles of $BaSO_4$ obtained are, 0.5 mole

Explanation : Given,

Moles of $BaCl_2$ = 0.5 mole

Moles of $H_2SO_4$ = 1 mole

The balanced chemical reaction will be,

$BaCl_2+H_2SO_4\rightarrow BaSO_4+2HCl$

According to the question, the $BaCl_2$ is a limiting reagent because it has less number of moles and $H_2SO_4$ is an excess reagent because it has more number of moles.

Now we have to calculate the moles of $BaSO_4$ by using the moles of limiting reagent because it limits the formation of products.

From the balanced reaction, we conclude that

As, 1 mole of $BaCl_2$ react to give 1 mole of $BaSO_4$

So, 0.5 mole of $BaCl_2$ react to give 0.5 mole of $BaSO_4$

Therefore, the amount of moles of $BaSO_4$ obtained are, 0.5 mole
