How many moles of H2O will be formed from the reaction of 80 g of
Roman55 [17]

Answer: 2 moles of H_2O will be formed.

Explanation:

To calculate the moles :

\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}    

\text{Moles of} NaOH=\frac{80g}{40g/mol}=2moles

The balanced chemical equation is:

H_2SO_4+2NaOH\rightarrow Na_2SO_4+2H_2O

According to stoichiometry :

2 moles of NaOH give = 2 moles of H_2O

Thus 2 moles of NaOH give =\frac{2}{2}\times 2=2moles of H_2O

Thus 2 moles of H_2O will be formed.

Calcium is a nontoxic metal that is used in supplements to maintain strong bones. Under high pressure conditions, over about 320
Lera25 [3.4K]

Explanation:

It is known that in a simple cubic unit cell the atoms are only present at the corner of the unit cell. This means that there are in total 8 atoms present in a simple cubic unit cell.

Therefore, in one simple cubic unit cell sharing of one atom is only \frac{1}{8}.

Hence, the total number of atoms in a unit cell will be as follows.

            8 \times \frac{1}{8} = 1

Thus, we can conclude that there is 1 calcium atom present in each unit cell.
