What is required for two atoms to share electrons equally in a chemical bond? A. The two atoms must have the same number of valence electrons.
B. The two atoms must both be nonmetals.
C. The two atoms must have equal and opposite charges.
D. The two atoms must be of the same element.

B

Explanation:

It said there "share electrons" so the two atoms should be non-metals

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.

8 m/s because for him to get the same amount of energy as ray is putting out, bobby, who weighs half as much as ray, needs to run twice as fast.
