Explanation Given: Moles of A = x Moles of B = x Molar mass of A = y Molar mass of B = 2y a) The molecules of gas B have greater kinetic energy than gas A. b) Gas B has greater partial pressure than gas A. c) The molecules of gas B have greater average velocity than those of gas A. d) Gas B makes a greater contribution to the average density of the mixture than gas A. a) The molecules of gas B have greater kinetic energy than gas A Kinetic energy = 1 2 m v 2 Lighter mass molecules have higher kinetic energy thus kinetic energy of A is greater than B. b) Gas B has greater partial pressure than gas A. Partial pressure is dependent on number of gas molecules and not on the molar mass and both have equal moles...

Ideal and Real Gases

Ideal gases obey conditions of the general gas laws under all states of pressure and temperature. Ideal gases are also named perfect gases. The attributes of ideal gases are as follows,

Gas Laws

Gas laws describe the ways in which volume, temperature, pressure, and other conditions correlate when matter is in a gaseous state. The very first observations about the physical properties of gases was made by Robert Boyle in 1662. Later discoveries we…

Gaseous State

It is well known that matter exists in different forms in our surroundings. There are five known states of matter, such as solids, gases, liquids, plasma and Bose-Einstein condensate. The last two are known newly in the recent days. Thus, the detailed fo…
