Which of the following best describes the amount of natural resources found here in the united states?
natural resources are found in abundance in the us.
coal is the only natural resource found in abundance in the us.

What is the typical rotational frequency frot for a molecule like n2 at room temperature (25∘c)? assume that d for this molecule is 1å=10−10m. take the total mass of an n2 molecule to be mn2=4.65×10−26kg. you will need to account for rotations around two axes (not just one) to find the correct frequency. express frot numerically in hertz, to three significant figures.

The activation energy for this reaction is 75 kj·mol–1. the enzyme catalase (found in blood) lowers the activation energy to 8.0 kj·mol–1. at what temperature would the non-catalyzed reaction need to be run to have a rate equal to that of the enzyme-catalyzed reaction at 25°c?

Among these processes, which is the slowest chemical reaction? a. digesting food b. boiling an egg c. tarnishing of silver d. melting of a glacier
