Consider two sample of gas has an identical 5.0L rigid containers. simple A contains one mole of hydrogen gas at 25°C. Simple be contains one mole of krypton and 25°C. select all the true statements about these two samples The molecules of hydrogen have the same average speed as the atoms of krypton

The molecules of I don’t have the greatest average speed

The items of krypton have the greatest average speed

The hydrogen and krypton are the same pressure

The hydrogen gas is a higher higher pressure

The krypton gas is a a higher pressure

please help quick

Bose-einstein condensation occurs at what temperature?

Achemist wants to extract copper metal from copper chloride solution. the chemist places 0.50 grams of aluminum foil in a solution containing 0.75 grams of copper (ii) chloride. a single replacement reaction takes place. (ii) chloride. a single replacement reaction takes place. which statement explains the maximum amount of copper that the chemist can extract using this reaction? a) approximately 0.36 grams, because copper (ii) chloride acts as a limiting reactant b) approximately 1.8 grams, because copper (ii) chloride acts as a limiting reactant c) approximately 0.36 grams, because aluminum acts as a limiting reactant d) approximately 1.8 grams, because aluminum acts as a limiting reactant

For the reaction c6h14(g) & longrightarrow; c6h6(g) + 4h2(g), δp(h2)/δt was found to be 2.5 x 10-2 atm/s, where δp(h2) is the change in pressure of hydrogen. determine δp(c6h14)/δt for this reaction at the same time.
