A sample of nitrous oxide (N2O) gas at 298.15 K is heated to 373.15 K and also allowed to expand from 1.50 L to 2.75 L. What is the final pressure of this gas in atm if the original pressure was 725 mmHg?

For many purposes we can treat ammonia NH3 as an ideal gas at temperatures above its boiling point of −33.°C. Suppose the temperature of a sample of ammonia gas is raised from 46.0°C to 78.0°C, and at the same time the pressure is increased by 5.0%. Does the volume of the sample increase, decrease, or stay the same? If you said the volume increases or decreases, calculate the percentage change in the volume. Round your answer to the nearest percent.

For many purposes we can treat ammonia (NH3) as an ideal gas at temperatures above its boiling point of −33. °C. Suppose the temperature of a sample of ammonia gas is lowered from 53.0 °C to 20.0 °C, and at the same time the pressure is decreased by 15.0%. Does the volume of the sample increase, decrease, or stay the same? If you said the volume increases or decreases, calculate the percentage change in the volume. Round your answer to the nearest percent. O increase decrease stays the same % x10 X Ś

A 44.0 L metal cylinder stores a sample of gas at 6 °C under 1.02 atm. The temperature of the storage unit rises to 76 °C, causing the gas to decompose and doubling the number of moles in the cylinder. Note: R = 0.08206 Latm/molK Determine the moles of gas in the cylinder before any decomposition occurs. Determine the pressure in the cylinder after the decomposition in atmospheres.

4. Another balloon is inflated to a volume of 1.250 L with dry hydrogen gas, at 28.0 °C. The balloon is then cooled, and its volume drops to 964 mL. If the pressure is unchanged, what is the hydrogen gas temperature (in °C) in the cooled balloon?  Assume that no gas has been added or removed.

The pressure of 8.40 L of nitrogen gas in a flexible container is decreased to one-half its original pressure, and its absolute temperature is increased to double the original temperature. What is the new volume?

1. If the pressure remains constant, what volume will 25.6 L of a gas at 84°C occupy at standard temperature? 2. A flask containing 90.0 L of hydrogen was collected at 75°C. At what temperature would the volume be 70 L? 3. A gas is confined in a cylinder. The starting temperature of the cylinder is 760.0 K and the volume is 2L. If the cylinder is cooled, reducing the temperature to 450.0 K, what is the new volume? 4. If a gas occupies a volume of 7.33 L at 10°C, at what temperature, in °C, will it occupy a volume of 12.25 L if the pressure remains constant? 5. A gas occupies a volume of 5.60 L at a temperature of 120°C. To what temperature must the gas be lowered, if it is to occupy 4.00 L?

When solid calcium carbonate is reacted with aqueous hydrochloric acid, the products of the reaction include aqueous calcium chloride, liquid water, and gaseous carbon dioxide. Calculate the volume of CO₂ gas (in L) collected over water at 25.0 °C when 25.1 g of calcium carbonate is added to excess hydrochloric acid if the total pressure is 911.0 mmHg. The vapor pressure of water at 25.0 °C is 23.8 mmHg.

A sample of an ideal gas at 1.00 atm and a volume of 1.89 L was placed in a weighted balloon and dropped into the ocean. As the sample descended, the water pressure compressed the balloon and reduced its volume. When the pressure had increased to 35.0 atm, what was the volume of the sample? Assume that the temperature was held constant.
