You are doing research on planet X The temperature inside the space station is a carefully controlled 26 °C and the pressure is 763 mmHg. Suppose that a balloon, which has a volume of 885 ml. inside the space station, is placed into the airlock, and floats out to planet X If planet X has an atmospheric pressure of 0.15 atm and the volume of the balloon changes to 3.15 L, what is the temperature, in degrees Celsius, on planet X (n does not change)? Express your answer using three significant figures. Submit ΑΣΦ Previous Answers Request Answer ? °C

A weather balloon is inflated with helium to a volume of 895.0 L at sea level, where the temperature is 30.0 °C and the barometric pressure is 760.0 torr. The balloon rises to an altitude of 4500.0 feet where the pressure is 645.0 torr and the temperature is 6.0 °C. What is the change in volume (in liters) of the balloon in going from sea level to 4500.0 feet?

The Haber Process synthesizes ammonia at elevated temperatures and pressures. Suppose you combine 1580 L of nitrogen gas and 4590 L of hydrogen gas at STP, heat the mixture to run the reaction, then isolate the ammonia from the reaction mixture. What volume of NH₃ , measured at STP, would be produced? Assume the reaction goes to completion. N₂ (g) + 3 H₂ (g) → 2 NH₃ (g)

A piece of dry ice (solid carbon dioxide) with a mass of 24.9 g sublimes into a large balloon. Assuming that all of the carbon dioxide ends up in the balloon, what is the final volume in Liters of the balloon if the temperature is 23.5 °C and the atmospheric pressure is 759.2 mmHg ?

The Haber Process synthesizes ammonia at elevated temperatures and pressures. Suppose you combine 1580 L of nitrogen gas and 4240 L of hydrogen gas at STP, heat the mixture to run the reaction, then separate the ammonia from the reaction mixture. What volume of reactant, measured at STP, is left over? Assume the reaction goes to completion. N₂ (g) + 3 H₂ (g) → 2 NH₃ (g)

A weather balloon is inflated to a volume of 26.8 L at a pressure of 736mmHg and a temperature of 30.7 degrees Celsius. The balloon rises in the atmosphere to an altitude where the pressure is 360 mmHg and the temperature is -14.7 degrees Celsius. Assuming the balloon can freely expand, calculate the volume of the balloon at this altitude.

A scuba diver exhales 3.00 L of air while swimming at a depth of 20.0 m, where the sum of the atmospheric pressure and water pressure is 3.50 atm. By the time the exhaled air rises to the surface, where the pressure is 1.00 atm, what is the volume if the temperature of air does not change during its travel. Show your work. Pay attention to significant figures.

2. Sodium sulfide (0,1159 g) and excess hydrochloric acid were reacted together to form 35.75 mL of an unknown gas. The gas was collected over water when the atmospheric pressure was measured to be 767 mmHg. The temperature of the water was 23.0°C. Determine the molar mass, as well as identity, of the gas. Hint: You will need to reference your textbook for the vapor pressure of water.

What is the experimental molar mass (that is, calculated from the data given and not taken from the periodic table) of magnesium if 0.0325 grams of magnesium generates 33.02 mL of hydrogen at 23.7 °C with a hydrogen partial pressure of 753.7 torr? Note that the partial pressure of water vapor has already been subtracted from the total pressure. 26.0 g/mol 18.8 g/mol 26.2 g/mol 24.2 g/mol 21.8 g/mol

A quantity of helium gas is originally held under a pressure of 145 kPa at 18°C. If the volume of the container is tripled, and the temperature is increased to 30°C, what is the resulting pressure in kPa? (Hint, can you make up a volume?)
