It takes 55.0 J to raise the temperature of an 10.3 g piece of unknown metal from 13.0C to 24.7 C. What is the specific heat for the metal?
a dry gas, held at a constant temperature, occupies a volume of 24.8 mL at 725 torr. What will be the volume of the gas at 800 torr
a TIre has a volume of 535 cm3 at a temprature of 20 c while in use the temprature of the tire rises to 65 c calculet the new volume of the tire assuming a constant pressure and amount of air?
Strong base is dissolved in 615 mL of 0.400 M weak acid (Ka = 4.50 × 10-5) to make a buffer with a pH of 3.95. Assume that the volume remains constant when the base is added.
The concentration of this compound in the sample is 0.000030 M and the path length of the sample is 1.0 cm
write the structural formulas for the two 2 chloro-isomers that can be formed from 2-methylpropane(isobutane)
Advantages and disadvantages of using Alternative Fuel and Would you consider buying one of these in the future? Why or Why Not and Why do you think there are not more of these vehicles in use?
Calculate the moles of N2 that will be in 224 L at STP and the partial pressure of O2 in Pa for air at 2.50 atm pressure
Calculating the molecular formula of an organic compound. Worked example, using fundamental formula and balanced equations.
At a pressure of 1.00 atm and a temperature of 20ºC, 1.72 g CO2 will dissolve in 1 L of water. How much CO2 will dissolve if the pressure is raised to 1.35 atm and the temperature stays the same?
A solution of NaOH(aq) contains 11.6 grams of NaOH in 129 mL of solution. Calculate the pH at 25C.
Kp for this reaction is 5.1 x 10-2 atm-1. Initially, 1.00 g each of SO2 and Cl2 are placed in a 1.00 L reaction vessel. After 15 minutes, the concentration of SO2Cl2 is 45.5 μg/mL.
Many gases are shipped in high-pressure containers. Consider a steel tank whose volume is 65.0L and which contains O2 gas at a pressure of 16,500kPa at 23°C.
