CO(g) +2H2--->CH3OH
2.50g H2*1mol/2g=1.25 mol H2
30.0L CO*1mol/22.4L=1.34 mol CO,
according to reaction 1 mol CO needs 2 mol H2,so 1.34 mol CO need 2.68 mol H2, so 1) limiting teactant is H2 (H)
2)1.25 mol CH3OH will be produced, 1.25 mol*32g/mol=40.0 g CH3OH
3) 1.25 mol H2 needs 0.625 g CO
1.34-0.625=0.715 g CO leftover
Cosmology is the study of the grand scale of the universe. You need astronomical observation because then there would be no proof to cosmological theory.
All electromagnetic waves are amplitude, a characteristic frequency and wavelength, and the ability to travel through a vacuum at the same speed (the speed of light)
If it is cooled the motion of the particles decreases as they lose energy.
4 Movement of less dense material
3 Heating of cooler material
1 cooling of warmer material
2 movement of denser material
