In the reaction of Zn with HCl, 140.15 g of ZnCl2 was actually formed, although the theoretical yield was 143 g. What was the percent yield?

Zn + 2HCl ➡ ZnCl2 + H2

Percent yield = 98%

Explanation:

Given data:

Actual yield of ZnCl₂ = 140.15 g

Theoretical yield of ZnCl₂  = 143 g

Percent yield = ?

Solution:

Formula:

Percent yield = (actual yield / theoretical yield )× 100

Percent yield = (140.15 g/ 143 g)× 100

Percent yield = 0.98 × 100

Percent yield = 98%

the reaction mixture contains some ammonia, plus a lot of unreacted nitrogen and hydrogen. the mixture is cooled and compressed, causing the ammonia gas to condense into a liquid. the liquefied ammonia is separated and removed. the unreacted nitrogen and hydrogen are then recycled back into the reactor .

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.
