4p + 5O2 -> P4O10 ; the percent yield of PO4O10 when 6.20 g of phosphorus burns into excess oxygen is 67.0%. What is the yiel
denis23 [38]

Answer:    36.9 g

Explanation:

P4 + 5O2 = P4O10  Balanced equation

moles P4 present = 23.9 g x 1 mole/123.88 g = 0.193 moles

moles O2 present = 20.8 g x 1 mol/32 g = 0.65 moles O2

From balanced equation, mole ratio O2 : P4 is 5:1.  Is 0.65 moles O2 5x 0.193 moles?  NO.  You don't have enough O2.

O2 is limiting in this reaction.

 

theoretical moles of P4O10 = 0.65 moles O2 x 1 mole P4O10/5 moles O2 = 0.13 moles P4O10

mass of P4O10 produced = 0.13 moles x 283.9 g = 36.9 g

A certain amount of gas at 25 C and at a pressure of 0.800 atm is contained in a glass vessel. Suppose that the vessel can with
sp2606 [1]

Answer:

=745 Kelvin

Explanation:

  • According to the pressure law the relationship between the pressure and absolute temperature of a  gas at a constant volume is directly proportional.
  • An increase in temperature causes a corresponding increase in pressure at a constant volume.

That is;

P\alpha T

Mathematically;

P = kT\\(Constant)k =\frac{P}{T} \\

When there are two varying conditions;

\frac{P1}{T1} =\frac{P2}{T2}

In this case;

P1 = 0.8 atm

T1 = 25+273 = 298 K

P2 =2.00 atm

T2= ?

Therefore;

T2= \frac{P2T1}{P1}

T2= \frac{(2)(298)}{0.8}

= 745 K

Therefore, the temperature can be raised up to 745 kelvin without bursting vessel.
