A chemical engineer must calculate the maximum safe operating temperature of a high-pressure gas reaction vessel. The vessel is a stainless-steel cylinder that measures 38.0 cm wide and 45.6 cm high. The maximum safe pressure inside the vessel has been measured to be 6.60 MPa. For a certain reaction the vessel may contain up to 1.71 kg of carbon monoxide gas. Calculate the maximum safe operating temperature the engineer should recommend for this reaction. Write your answer in degrees Celsius. Round your answer to 3 significant digits.

A sample of gas occupies a volume of 68.0 mL. As it expands, it does 129.1 J of work on its surroundings at a constant pressure of 783 Torr. What is the final volume of the gas? V = mL

21 Consider the combustion of in oxygen gas to produce carbon dioxide gas and water vapor. In an experiment, 0.1063 g of C₅H₈ is combusted to produce enough heat to raise the temperature of 150.0 g of water by 7.632 °C. C₅H₈ (l) + 7 O₂ (g) → 5 CO₂ (g) + 4 H₂O (g) d If 4790 J of heat were absorbed by the water, then how much heat, in J, was produced by the combustion of C₅H₈? (include the appropriate sign)

thermometer. A sample of aluminum, which has a specific heat capacity of 0.897 J·g *.°C*, is put into a calorimeter (see sketch at right) that insulated container contains 100.0 g of water. The aluminum sample starts off at 91.4 °C and the temperature of the water starts off at 19.0 °C. When the temperature of the water stops changing it's 26.9 °C. The pressure remains constant at 1 atm. water Calculate the mass of the aluminum sample. Be sure your answer is rounded to 2 significant digits. sample a calorimeter x10

A sample of gass occupies a volume of 56.4mL. As it expands, it does 133.3J of work on its surroundings at a constant pressure of 783 torr. What is the final volume of gas?

An electric heater supplies 43.3 joules of energy to 27.3-g sample of H2 gas originally at 27.6 °C. Compute the final temperature (in °C). i °C

A piston has an external pressure of 14.0 atmatm. How much work has been done in joules if the cylinder goes from a volume of 0.160 liters to 0.620 liters? Express your answer with the appropriate units.

A copper block with an initial temperature of 12 °C is dropped into 577g of water initially at 77 °C, and they reach an equilibrium temperature of 65 °C. Determine the mass of the copper block.

When answering this problem, report the answer with the appropriate number of significant figures. When entering units, use proper abbreviated units with proper capitalization. A student followed the procedure in this experiment, using 50.00 mL of 2.00 molar HCl and 51.00 mL of 2.00 molar NaOH both solutions having an initial temperature of 22.7 oC.  After mixing, a maximum temperature of 32.2 oC is measured. The final mass of the mixture was found to be 107.87 grams.  For this problem, assume the  specific heat of the solution is 4.18 J/g oC. Report all answers with the proper number of significant figures.  What is the heat transferred by this reaction, in Joules?
