A metal object with a mass of 19g is heated to 96 degrees Celsius, then transferred to a calorimeter containing 75g of water a1 18 degrees Celsius. The water and metal object reach a final temperature of 22 degrees Celsius. What is the specific heat of this metal object? What is the metal?
A close chemical relative of the banned insecticide DDT is methoxychlor (C16H15Cl3O2). Methoxychlor is currently used as a home insecticide. Calculate the mass percent of oxygen in methoxychlor.
The pH would decrease slightly. The pH would decrease dramatically. The pH would increase slightly. The pH would increase dramatically. The pH would not change at all.

Determine how many milligrams of H 2 O are present in sample If the freezing point of a 100.0g sample of 2-methyl-2-propanol =24.59C?
It is heated so that its pressure increases from 1.50 atm to 407 atm. Determine the work done on the gas during this process.
The reaction 2NO (g)-> N2 (g) + O2 (g) has a H = 180.5 kJ. How much heat will be required to produce 44.8 L of NO by the reverse reaction?
After the vessel was pressurized with hydrogen gas and heated to 80 degrees C, the monometer showed the initial pressure inside the "bomb" to be 77.2 atm. Assuming 100% yield, calculate the pressure that should be inside the "bomb" when the reacti..
Calculate the pressure in atmospheres using both the ideal gas law and the van der Waals equation. For N2, a=1.35(L^2 x atm)/mol^2, and b=0.0387L/mo
A balloon is filled to a volume of 9.00 multiplied by 102 mL at a temperature of 18.0°C. The balloon is then cooled at constant pressure to a temperature of 1.00 multiplied by 102 K. What is the final volume of the balloon?
