Which gas will diffusion faster within a system?
kifflom [539]

Answer:

Methane(CH₄).

Explanation:

  • Thomas Graham found that, at a constant  temperature and pressure the rates of effusion  of various gases are inversely proportional to  the square root of their masses.

<em>∨ ∝ 1/√M.</em>

where, ∨ is the rate of diffusion of the gas.

M is the molar mass of the gas.

<em>∨₁/∨₂ = √(M₂/M₁)</em>

<em></em>

  • The molar mass of different choices:

Carbon dioxide: 44.01 g/mol.

Water vapor : 18.0 g/mol.

Ammonia (NH₃): 17.0 g/mol.

Methane(CH₄): 16.0 g.mol.

<em>Since, methane has the lowest molar mass. So, it will diffuse faster within a system.</em>

A 50g ice cube at 0 degrees celcius is added to a glass containing 400g of water at 45 degrees celcius. What is the final temper
PolarNik [594]
In a system, heat that is gained and lost should be conserved. We calculate as follows:

Heat from phase change + sensible heat from the change in tempeture of the ice = sensible heat from the change in temperature of water

mH(fusion) + mCpΔT = mCpΔT
.05 (335) + .050(4.184)( T - 0) = .4 (4.184)(45 - T)
T = 34.8 °C
