A perfectly elastic 170L balloon is heated from 25.0°C to 62.3°C. To what volume (L) will it expand?

A balloon full of air (starting at 298 K and 4.0 L) was placed in a cooler full of liquid nitrogen.  After cooling, the final volume of the balloon was 1.3 L.  What was the final temperature (in ºC) of the balloon?

Nitric acid is a key industrial chemical, largely used to make fertilizers and explosives. The first step in its synthesis is the oxidation of ammonia. In this reaction, gaseous ammonia reacts with dioxygen gas to produce nitrogen monoxide gas and water. Suppose a chemical engineer studying a new catalyst for the oxidation of ammonia reaction finds that 594. liters per second of dioxygen are consumed when the reaction is run at 276. °℃ and the dioxygen is supplied at 0.51 atm. Calculate the rate at which nitrogen monoxide is being produced. Give your answer in kilograms per second. Be sure your answer has the correct number of significant digits. kg S × Ś

A closed-ended manometer is filled with gas. The ∆h of the column of Hg in the manometer is3.56 cm. What is the pressure of gas in the manometer (in atm)?

Assuming that the natural gas used in a lab is pure methane, CH4, write a balanced chemical equation for the reaction of natural gas with each of the copper oxides, (Red copper oxide Cu2O, and Black copper oxide, CuO). Assume the products for both reactions are copper metal, water vapor, and carbon dioxide gas. Include all phases in the reactions.

A A 20.0L balloon is heated from 25°0C to lo5.00 What is the new Volume ?

What is the temperature if 5.00 g of methane (CH4, MW = 16.04 g/mol) in a 100.0 mL container exerts a pressure of 42.0 atm?

A hot air balloon is filled with 1.35×10^6  of an ideal gas on a cool morning (11 ∘C). The air is heated to 101∘C. What is the volume of the air in the balloon after it is heated? Assume that none of the gas escapes from the balloon.
