Most lighters contain butane. When butane is burned in the presence of oxygen, the heat of combustion for this reaction is know to be -2856kJ. You place a 35.0 g water at 12.5 degrees C above a lighter and ignited the lighter. If the lighter initially weighed 10.25 g and weighed 8.806 g what would be the final phase and temperature of the H2O.
A 35.6 g sample of ethanol (C2H5OH) is burned in a bomb calorimeter, according to the following reaction. If the temperature rose from 35.0 to 76.0°C and the heat capacity of the calorimeter is 23.3 kJ/°C, what is the value of DH°rxn. The molar ma..
A chemist burns a a saltine cracker in a calorimeter containing 2.0 kg of water. The water temperature increases from 25.0°C to 29.7°C. Calculate the heat content of the cracker in J per cracker.
Oxygen masks for producing O2 in emergency situations contain potassium superoxide, KP2. It reacts with CO2 AND H2O in exhaled air to produce oxygen
At 0.0oC, if the volume of air is 2.5 mL and the pressure of the atmosphere that day is 835 mmHg, what is the number of moles of air?

A 15.00 mL sample of unknown concentration of sulfuric acid is precititated with excess lead(II) nitrate and a precipitate of lead(II) sulfate is collected.
The reactions that occur are CH4 + 2 O2 = CO2 + 2 H2O and 2 C2H6 + 7 O2 = 4 CO2 + 6 H2O. How many grams of oxygen are needed to react completely with 50.0 grams of the hydrocarbon mixture
If 500 mL of air contains 2 x 1022 particles (atoms and molecules), how many particles do you inhale in one day if you breathe 15000 L of air?
the density of liquid octane, H8H18, is 0.7025g/ml. if 1.00ml of liquid octane is vaporized at 100 degrees 100'c and 725 torr, what volume does the vapor occupy?
