. How many litres of hydrogen gas will be produced by the decomposition of 90 L of water? (Assume that temperature and pressure are constant.) 2H2O(g) 2H2(g) + O2(g)

Calculate the volume occupied by 25.8 g of methane gas (CH4) at 28°C and 1.0 atm (R = 0.0821 L·atm·K-1·mol-1). 0.039 L 8.7 L 39.8 L 99.2 L 59.7 L

A 10.0 L sample of CO2 gas at 25.0 degrees celsius is heated at a constant pressure until the volume has doubled. What is the final ideal temperature of CO2 in degrees celsius?

6. The ideal gas law is a very simple mathematical relationship that relates several physical properties of a gas. This law is only valid when the behavior of a gas is idealized according to three principal assumptions. (i) State the three assumptions made about an ideal gas, and for each assumption (ii) explain which physical property of a gas would be affected if that assumption was not made.

Please don't provide handwritten solution ....

For many purposes we can treat ammonia (NH, ) 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 13.0 °C to –16.0 °C, and at the same time the pressure is increased by 10.0%. increase x10 Does the volume of the sample increase, decrease, or stay the same? decrease ? stays the same If you said the volume increases or decreases, calculate the percentage change in % the volume. Round your answer to the nearest percent.

Find the volume of O2 (at STP) formed when 33.4 g of KClO3 decomposes according to the following reaction.  molar mass for KClO3 is 122.55 g/mol. 2 KClO3(s)  →  2 KCl(s) + 3 O2(g)

1.What is the temperature of the gas? 2.Determine the volume (in L)
