Answer: 4 moles of Na are needed to produce 4 moles of NaCl
Explanation:
The balanced chemical equation is :
According to stoichiometry :
2 moles of 
are formed from = 2 moles of 
Thus 4 moles of will be formed from = 
of
Thus 4 moles of Na are needed to produce 4 moles of NaCl
<span>The scientific knowledge that
was necessary for Schrodinger’s work is the Bohr’s model. Unlike the Bohr
model, the quantum model does not define the exact path of an electron. The electron
is likely to be in a less dense area of cloud.</span>
