1) copper oxide and carbon combine to produce metallic copper. which of these is the balanced equation for this reaction? a. cu2o+c -> 2cu+co2 b.2cu2o+c -> 4cu+co2 c.3cu2o+c -> 3cu+co2 d.2cu2o+2c -> 2cu+2co2

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.

i think the answer is terrae but not 100 percent sure. ▓▬▬ §
