6. Problems. Be sure to BALANCE every equation before trying to solve the problems. [Balancing is 1 point; problems are generally 1 point per question] C3H8 + O2  CO2 + H2O

a. How many moles of oxygen gas are needed to react completely with 1.7 moles of propane?

b. How many moles of CO2 are produced if 2.1 moles of water are produced?

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.

possibly, yes.
