A 47 kg sample of water absorbs 388 kj of heat. If the water was initially at 27.6 Celcius, what is its final temperature?
what is the equilbrium constant, K for the reaction A + B -> AB. What would the equilbrium constant be if A, B, and AB were each present in equilibrium at a concentration of 1nM
If the volume of the gas sample is decreased to 15.3 L holding the temp constant, the average molecular speed will increase, decrease or remain the same?
You are given a box containing at equilibrium at 1000 K 0.102 moles/liter NH3, 1.03 moles/liter N2, and 1.63 moles/liter H2 for the reaction N2(g) +3 H2(g)-->/
What is the freezing point of a solution of 1.17 g of 1-naphthol, C10H8O, dissolved in 2.00 mL of benzene at 20°C? The density of benzene at 20°C is 0.876 g/mL. Kf for benzene is 5.12°C/m, and benzene's normal freezing point is 5.53°C.
Assume that the volume of Earth's oceans is 137 x 10^7 km^3 and that the density of seawater is 1.03 g/cm^3. Also assume that the heat capacity of seawater is the same as that of water.
explain why the pure solvent shows a level horizontal curve as solidification occurs but the curve for the solution
A cylinder is separated into two sections Y and Z by an insulating frictionless piston and sealed at both ends. Each section has two moles of an ideal gas.
A thermos container has 0.075 kilograms of distilled water at a temperature of 27 degrees Celcius. A 0.0076 kilogram sample of solid ammonium nitrate is dissolved in the water in the Thermos container and the temperature is measured to be 22.4 deg..
