Answer:

Explanation:

This principles determines the manner in which atomic orbitals of an element filled with electrons. According to the principle, orbitals are filled by electrons on the basis of increasing order of orbital energy level. It can be used to determine the location of electrons in an atom.

However, chromium, silver, etc. are the exception because of the increased stability provided by the half-filled or filled sub-shells and also due to the presence of energy gap between the sub-shells.

What mass of sodium hydroxide will completely neutralize 2.5 mol of sulfuric acid?
VMariaS [17]

Given :

2.5 mole of Sulfuric acid ( H_2SO_4 ) .

To Find :

Mass of sodium hydroxide will completely neutralize 2.5 mol of sulfuric acid

Solution :

Let us assume volume of water be 1 L .

Now , we know , to neutralize 1 mole of sulfuric acid we need 2 moles of NaOH .

So , for 2.5 mole sulfuric acid required 5 mole of NaOH .

Moles of NaOH ,

n=M\times Volume \\\\n=5\times 1=5\ moles  

Molecular mass of NaOH , M.M = 58.44 g/mol .

Mass of 5 moles of NaOH :

m=5\times 58.44\ g\\\\m=292.2\ g

Hence , this is the required solution .
