What types of isotopes do the various elements have?

1 answer:

4 0

There isn't really a specific number of isotopes that elements have to have. But the isotopes are determined by the average mass of the element found in nature. And elements have varying masses because neutrons) leave and enter the atom. (neutrons are big enough that leaving the atom cause a difference in mass but electrons leaving will not, since they are so small)

How many moles of Na are needed to produce 4 moles of NaCl in the

Alja [10]

Answer: 4 moles of Na are needed to produce 4 moles of NaCl

Explanation:

The balanced chemical equation is :

$2Na+Cl_2\rightarrow 2NaCl$

According to stoichiometry :

2 moles of $NaCl$ are formed from = 2 moles of $Na$

Thus 4 moles of $NaCl$ will be formed from = $\frac{2}{2}\times 4=4moles$ of $Na$

Thus 4 moles of Na are needed to produce 4 moles of NaCl
