The Problem
A sample of N2 gas is contaminated with a gas. It is found that that contaminant effuses at 0.25 times the rate of N2. What is the contaminating gas?
Choices are: He, Cl2, H2, Kr, Rn
Homework Equations
Rate x/Rate N2 = (square root of:) Mass N2/Mass x
Where Rate x...
HELP! Pressure Change for equation without volume
Homework Statement
A tank is pressurized with 5.0 atm of N2 and 10.0 atm of H2. Ammonia (NH3) is formed. When the pressure finally remains constant, indicating that the reaction has proceeded as far as it will go, the partial pressure of...
Homework Statement
What quantity of ice at 2 deg Celsius can be melted by 100 J of heat?
Homework Equations
q = m c (delta) t (mass x specific heat x change in temp)
q = m l (mass x heat of fusion)
specific heat of ice = 2.09 j/g-K
heat of fusion = 6.01 kJ/mol
