There are two important isotopes of uranium: 235U and 238U. These isotopes have different atomic masses and react differently. Only 235U is very useful in nuclear reactors. One of the techniques for separating them (gas diffusion) is based on the different RMS speeds of uranium hexafluoride gas, UF6.
The molecular masses for UF6 with 235U and UF6 with 238U are 349.0 g/mol and 352.0 g/mol, respectively.
What is the ratio of RMS speeds?

How have the greenhouse gasses increased from the year 2000 to 2018

Effect of rotenone and antimycin a on electron transfer rotenone, a toxic natural product from plants, strongly inhibits nadh dehydrogenase of insect and fish mitochondria. antimycin a, a toxic antibiotic, strongly inhibits the oxidation of ubiquinol. (a) explain why rotenone ingestion is lethal to some insect and fish species. (b) explain why antimycin a is a poison. (c) given that rotenone and antimycin a are equally effective in blocking their respective sites in the electron-transfer chain, which would be a more potent poison? explain.

How will the volume of a gas be affected if the pressure is tripled, but the temperature remains the same?
