Zinc reacts with iodine in a synthesis reaction. using a balanced chemical equation for the reaction, determine the percent yield of a 125.0gram sample of zinc was used and 515.6 grams of product is recovered

84.48%

Explanation:

Let's consider the following synthesis reaction.

Zn + I₂ → ZnI₂

We can establish the following relations:

The mass of ZnI₂ (theoretical yield) to be obtained from 125.0 g of Zn is:

The real yield of ZnI₂ is 515.6 g. The percent yield is:

(515.6 g/610.3 g) × 100% = 84.48%

air quality

poor drinking water

and heavy polution

can lead to poor health

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
