First, calculate the amount fo Na2O that should be produced with the given amount of sodium using proper dimensional analysis and the balanced chemical reaction,
theoretical amount of Na2O = (54.1 g of Na)(1 mol Na/23 g Na)(2 mos Na2O/4 mols Na)(62 g Na2O/ 1mol Na2O)
theoretical amount of Na2O = 72.9 g of Na2O
Calculation of percent yield,
% yield = (61.8 g Na2O) / (72.9 g of Na2O) x 100%
% yield = 84.75%
Answer: 84.75%
In the given reaction Fe³⁺ + 2H₂O ⇄ FeOH²⁺ + H₃O⁺ Lewis acid is Fe³⁺ and the Lewis base is H₂O.
<h3>
What is a Lewis acid and Lewis base?</h3>
- According to the Lewis theory of acid-base reactions, acids accept pairs of electrons and bases donate pairs of electrons.
- Any substance like H+ ion, which is capable of accepting a pair of nonbonding electrons or an electron-pair acceptor is known as a Lewis acid.
- Any substance, like the OH- ion, that is capable of donating a pair of nonbonding electrons or an electron-pair donor is a Lewis base.
- From the Lewis theory, with no change in the oxidation numbers of any atoms, acids react with bases to share a pair of electrons.

Answer:
B
Explanation:
The ratios of the coefficient of the compounds in a balanced chemical equation tells us the relationship of each compound to the others in terms of mole.
Based on the equation,
3 moles of CO₂ would require 2 moles of phosphoric acid.
3 mol CO₂ ------- 2 mol H₃PO₄
1.5 mol CO₂ ------- 2 ÷2= 1 mol H₃PO₄
Or 1.5 mol would require 
mol of H₃PO₄
To find mass of H₃PO₄, multiply the number of moles by its Mr, which can be deduced with the help of the periodic table.
Ar of H₃PO₄
= 3(Ar of H) + Ar of P +4(Ar of O)
= 3(1) +31 +4(16)
= 98
Multiply 98 with the number of moles, 1, to obtain the answer.
So if you would look at the steps above, here's what we did:
