A 25 liter gas cylinder contains 10 mole of carbon dioxide. Calculate the pressure, in atm, of the gas at 325K.
Arada [10]

<u>Answer:</u> The pressure of carbon dioxide gas is 11 atm

<u>Explanation:</u>

To calculate the pressure of gas, we use the equation given by ideal gas equation:

PV = nRT

where,

P = pressure of the gas = ?

V = Volume of gas = 25 L

n = number of moles of gas = 10 mole

R = Gas constant = 0.0821\text{ L atm }mol^{-1}K^{-1}

T = temperature of the gas = 325 K

Putting values in above equation, we get:

P\times 25L=10mol\times 0.0821\text{ L atm }mol^{-1}K^{-1}\times 325K\\\\P=11atm

Hence, the pressure of carbon dioxide gas is 11 atm

Glaciers also _____ materials in new places when they melt.
natali 33 [55]

Deposits

Explanation:

Glaciers also deposits materials in new places when they melt.

  • Glaciers are made up of snow flakes that has compressed through time.
  • In temperate and polar regions where they are prevalent, they are powerful agents of denudation.
  • They can erode, transport and deposit earth materials in places.
  • When a glacier retreats by melting, it deposit some of its materials in new places.
  • Most of this sediment are called tillites.
  • They are made up of unsorted materials of different size grains.

Calculate the heat change in calories for melting 65 g of ice at 0 ∘c.
Genrish500 [490]

When ice melts, the physicals state changes from solid to liquid. The energy or the heat required (q) required to change a unit mass (m) of a substance from solid to liquid is known as the enthalpy or heat of fusion (ΔHf). The variables; q, m and ΔHf are related as:

q = m * ΔHf

the mass of ice m = 65 g

the heat of fusion of water at 0C = ΔHf = 334 J/g

Therefore: q = 65 g * 334 J/g = 21710 J

Now:

4.184 J = 1 cal

which implies that: 21710 J = 1 cal * 21710 J/4.184 J = 5188.8 cal

Hence the heat required is 5188.8 cal or 5.2 Kcal (approx)
