The reaction of 75.0 g p4 with excess chlorine gas produces 110 g pcl3 in lab. calculate the percent yield for the reaction.

Answers

Answer 1

The reaction of 75.0 g p4 with excess chlorine gas produces 110 g pcl3 in lab. The percent yield for the reaction is 32.7%.

P4+ 6 Cl2 4PCl3

moles of P4 in 75 g

n=m/M

where n = moles; m= mass; M = molar mass

M(P4) = 4× 30.974 g/ mol

P = 123.896g/mol

n can be given as

n(P4) = (75) / 123.896

= 0.60535 mol

Total=

0.60535 mol P4 × 4 mol/1 mol P4

= 2.4214 mol PCl3

mass of PCl3

m= n×M

M = 30.974 g/mol P+(3× 35.45g/mol Cl)

= 137.32g/mol

m= 2.4212 mol× 137.32g/mol

=333 g

The yield of PCl3 is 333 g.

The theoretical yield of PCl3 is 110 g.

percent yield can be given as

(percent yield/ theoretical yield) × 100

%yield = (333/110) ×100

Thus, the percent yield of PCl3 is 32.7%.

12.28 L volume at 6.98atm in sample gas occupies 10. 28 l at 8. 34atm. Hence, option A is correct.

What is ideal gas?

Ideal gas is a hypothetical gas whose molecules occupy negligible space and have no interactions, and which consequently obeys the gas laws exactly.

In the limit of low pressures and high temperatures, where the molecules of the gas move almost independently of one another, all gases obey an equation of state known as the ideal gas law:

PV = nRT,

P is pressure of gas (atm)T is temperature of gas (K)where n is the number of moles of the gas R is the universal gas constant, 8.3145 joules/K.

When Temperature is constant so, it follow Boyle's law:

P1 V1 = P2 V2

P1 = 8.34atm, V1 = 10.28 L, P2 = 6.98atm

V2 = P1 V1 / P2

V2 = 8.34atm x 10.28 / 6.98atm

V2 = 12.28 L

12.28 L volume at 6.98atm in sample gas occupies 10. 28 l at 8. 34atm. Hence, option A is correct.

When the ph of an aqueous solution is changed from 1 to 2, the concentration of hydronium ions in the solution is.

Answers

Answer:

Explanation:

pH is defined in such a way that;

pH= −log10(H)

Where H represents the concentration of Hydronium or Hydrogen ions

Given that pH is changed from 1 to 2,

By rearranging the above formula , we get 10−pH = H

if pH=1,H=10−1=0.1Mif pH=2,H=10−2=0.01M

Hypothesis: How will molecular size affect the rate of evaporation and how will this correlate

Answers

A molecular size affects the rate of evaporation when the larger the intermolecular forces in a compound, the slower the evaporation rate and this correlates with temperature change.

Molecular size seems to have an effect on evaporation rates in that the larger a molecule gets or grows from a base chemical formula, its evaporation rate will get slower.

What is the molecular size?

This is a measure of the area a molecule occupies in three-dimensional space as this relates to the physical size of an individual molecule.

Diffraction lines occur at angles θ such that dsinθ=mλ, where λ is the wavelength and m is an integer.

Notice that for a given order, the line associated with a long wavelength is produced at a greater angle than the line associated with a shorter wavelength.

We take λ to be the longest wavelength in the visible spectrum (538nm) and find the greatest integer value of m such that θ is less than 90°.

That is, find the greatest integer value of m for which mλ<d.

pOH = -log (OH^-). Then

pOH = -log (0.075)
