A mxiture of n2 and H2 has mole fraction of 0.4 and 0.6 respectively. Determine the density of the mixture at one bar and 0 c.
SOVA2 [1]

Answer:

The density of the mixture is 0.55kg/m^3

Explanation:

P = 1bar = 100kN/m^2, T = 0°C = 273K, n = 0.4+0.6 = 1mole

PV = nRT

V = nRT/P = 1×8.314×273/100 = 22.70m^3

Mass of N2 = 0.4×28 = 11.2kg

Mass of H2 = 0.6×2 = 1.2kg

Mass of mixture = 11.2 + 1.2 = 12.4kg

Density of mixture = mass/volume = 12.4/22.7 = 0.55kg/m^3

A rock is dropped at the same instant that a ball at the same height is thrown horizontally. which will will have the greater sp
Svetach [21]
They will both hit the ground at the same time due to gravity.
that means they took the same time to travel the distance to the ground

however, the ball traveled farther
speed=distance (or displacement) divided by time
so the greater the distance, the greater the speed

the ball traveled faster in the same time so it traveled faster

answer is ball
