The equation below shows the decomposition of lead nitrate. how many grams of oxygen are produced when 11.5g NO2 is formed?

1 answer:

7 0

Number of moles of NO2 = 11.5/(14+16x2) =0.250mol
Mole ratio: 4NO2 to 1O2
Number of moles of O2=0.250/4 =0.0625mol
Mass of O2 produced= 0.0625x32 =2g
Answer: B

2 moles of a gas have a pressure of 2 atm at a temperature of 300 K. What is the volume of the gas?

qwelly [4]

No of moles=2mol=n
Pressure=2atm=P
Temperature=300K=T
Volume=V

$\\ \tt\hookrightarrow PV=nRT$

$\\ \tt\hookrightarrow V=\dfrac{nRT}{P}$

$\\ \tt\hookrightarrow V=\dfrac{2(8.314)(300)}{2}$

$\\ \tt\hookrightarrow V=8.314(300)$

$\\ \tt\hookrightarrow V=2494.2mL$

$\\ \tt\hookrightarrow V=24.94dm^3$

Olenka [21]

The answer is "c" because solidification or freezing is the term used for the process in which a liquid becomes a solid.<span> Freezing is an exothermic process that also is an example of a phase transition</span>
