I teach high school chemistry.
Infer If increasing the temperature of a reaction by 10 K approximatelydoubles the reaction rate, what would be the effect of increasing thetemperature by 20 K?
Plastic Bags Thin sheets of plastic are used to make items such as grocery bags. The sheets move under a source of promethium-147, emitting beta particles. The radiation intensity, measured under the plastic sheets, is used to monitor the thickness of the plastic. During this process, promethium changes into which element?
What trade-offs must be made between kinetics and thermodynamics in the Haber process for the production of ammonia? How did the discovery of an appropriate catalyst make the process feasible?
What are boranes? Why were they once considered as potential fuels for rockets?
Write balanced equations describing the reaction of lithium metal with each of the following: $\mathrm{O}_{2}, \mathrm{S}, \mathrm{Cl}_{2}, \mathrm{P}_{2}, \mathrm{H}_{2}, \mathrm{H}_{2} \mathrm{O},$ and $\mathrm{HCl} .$
