Explanation:
B ia the correct one .
Hydrogen only uses the first energy shell, which holds 2 electrons, not 8.
Write out the eqn of magnesium and oxygen. this should be under “metals” chapter. do revise.
next, find the mols of both oxygen and magnesium. compare the ratios and find the LIMITING REAGENT.
use the mols of the limiting reagent to compare with the mols of the product.
take the mols of the product/mr of the product.
this will give u the mass.
It’s probably probably 01/16 because of the other number don’t make sense except that one
Answer:
The reactants would appear at a higher energy state than the products.
Have a nice day!
