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 .

Which type of bonding is characterized by overlapping orbitals that allow outer electrons of atoms to move about freely througho
Sonja [21]

Answer:

D metallic

Explanation:

The chemical bonding which rises from electrostatic attractive force between the conduction electrons and the positively charged metal ions is called metallic bonding.

<u>It is sharing of the free electrons among the structure of the positively charged ions which are known as cations. </u>

<u>In this type of bonding, these free electrons freely move in the crystal mattice of the metal.  </u>

The bonding accounts for properties of metals, such as ductility, strength,  electrical and thermal conductivity and resistivity and luster.
