Question

Calculate the number of moles of H2O formed when 0.200 mole of Ba(OH)2 is treated with 0.500 mol of HCIO3 according to the chemical reaction shown below. Ba(OH)2+2HCIO3 ----> Ba(Clo3)2+ 2 H2O

Answer 1

Answer : The number of moles of  formed are, 0.0250 mole

Explanation : Given,

Moles of  = 0.1 mole

Moles of  = 0.0250 mole

First we have to calculate the limiting and excess reagent.

The balanced chemical reaction is,

From the balanced reaction we conclude that

As, 1 mole of  react with 2 moles of  

So, 0.1 moles of  react with  moles of  

That means, in the given balanced reaction,  is a limiting reagent because it limits the formation of products and  is an excess reagent.

Now we have to calculate the moles of .

As, 2 moles of  react to gives 2 moles of  

So, 0.0250 moles of  react to gives  moles of  

Therefore, the number of moles of  formed are, 0.0250 mole
