The combustion of hydrogen and oxygen is commonly used to power rocket
engines:
2H2 (g) + O2 (g) → 2H20 (g)
If the final pressure of water vapor was 0.875 atm and the temperature is 400. K,
how many mols of H20 was produced assuming that the reaction went to
completion in a 250. L engine?
mols

african americans demonstrated their newly found freedom by relocating often in search of relatives whom they had been separated from during slavery. others established schools to educate freed people and they built institutions such as churches and political organizations to advocate for their rights.

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.
