Answer:

Ice act and help in condensation of the vapor

Explanation:

The energy released when gaseous water vapor condenses to form liquid water droplets is called latent heat. Latent heat from condensation causes an increase in air temperature surrounding the water droplets. The warmer air rises, causing the water vapor to condense when it meets cooler air at a higher altitude

A self-contained underwater breathing apparatus (SCUBA) uses canisters containing potassium superoxide. The superoxide consumes

emmainna [20.7K]

Answer:

52.0004 grams of mass of potassium superoxide is required

Explanation:

Let moles carbon dioxide gas be n at 22.0 °C and 767 mm Hg occupying 8.90 L of volume.

Pressure of the gas,P = 767 mm Hg = 0.9971 atm

Temperature of the gas,T = 22.0 °C = 295.15 K

Using an ideal gas equation to calculate the number of moles.

$PV=nRT$

$n=\frac{0.9971 atm\times 8.90 L}{0.0821 atm L/mol K\times 295.15 K}$

n = 0.3662 mol

$4KO_2(s)+2CO_2(g)\rightarrow 2K_2CO_3(s)+3O_2(g)$

According to reaction, 2 moles of carbon-dioxide reacts with 4 moles of potassium superoxide.

Then 0.3662 mol of of carbon-dioxide will react with:

$\frac{4}{2}\times 0.3662 mol=0.7324 mol$ of potassium superoxide.

Mass of 0.7324 mol potassium superoxide:

0.7324 mol × 71 g/mol = 52.0004 g

52.0004 grams of mass of potassium superoxide is required.
