The rate constant of the elementary reaction CH3OCH3 (g) CH4 (g) + CH2O (g) is k = 8.33*10-6 s-1 at 427°C, and the reaction has an activation energy of 245 kJ mol-1. (a) Compute the rate constant of the reaction at a temperature of 545°C.

Why does mass wasting occur faster on a steep slopes? A. There is less resistance on steep slopes. B. The force of gravity causes mass wasting to occur faster. C. Rain falls on steep slopes often which wears them away faster. D.

In this lab, we do not measure the amount of chlorine in the sample, We need the amount of chlorine to determine the formula of the compound.

What does the law of conservation of energy state about energy in a closed system? Energy cannot be created or destroyed. Energy can be created but not destroyed. O Energy can be destroyed but not created. O Energy can be either troyed or created.

A measure of the internal energy that has been absorbed or transferred from one body to another is
