Explanation:
It depends if the zinc ion lost or gained an electron. But electrons are more than 2,000 times smaller than a proton or neutron so small diffrence.
The balanced reaction:
<span>4Na + O2 = 2Na2O
We use the relation of the substances and the amount of sodium to determine the theoretical yield of the reaction. This yield is the amount produced if all the reactant is consumed.
2.55 mol Na (2 mol Na2O / 4 mol Na) ( 61.98 g / 1 mol ) = 79.02 g Na2O
Percent yield = 75.0 / 79.02 x 100 = 94.91%</span>
