Zn + I2 = ZnI2
Percentage yield = actual yield / theoretical yield * 100
Actual yield of ZnI2 = 515.6g
Mole of zinc reacted = 125 / 65.4 = 1.91 mol
for every 1 mole of zinc will form 1 mole of ZnI2
Mole of ZnI2 formed = 1.91 * 1 = 1.91 mol
Theoretical yield of ZnI2 = 1.91 * (65.4 + 126.9*2) = 609.672 g
515.6 / 609.672 * 100 = 84.6%
Answer:
sulfuric acid ..............
Answer: The partial pressure of neon in the mixture is 263 mm Hg
Explanation:
According to Dalton's law, the total pressure is the sum of individual pressures.
Given :
=total pressure of gases = 815 mm Hg
= partial pressure of helium = 201 mm Hg
= partial pressure of nitrogen = 351 mm Hg
= partial pressure of Neon = ?
putting in the values we get:
The partial pressure of neon in the mixture is 263 mm Hg
