How do air pressure and precipitation determine the weather in a certain area? A:When the air pressure is higher, the air is cooler, and it is less likely for precipitation to fall.
B:When the air pressure is lower, it is harder for evaporation to occur and for the rain to form.
C:When the air pressure is higher, the humidity is higher, and the chance of precipitation is lower.
D:When the air pressure is higher, the air is warmer, and the chance of precipitation is higher.

When balancing a chemical equation:

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.

I'm learning about the periodic tables and what each subject's configuration is. for example, hydrogen is 1s^1, but i don't understand how you get that. can someone me understand how to figure out how to figure this out? sorry if the question makes no sense, but it would really a lot if you could me understand! you so much if you can!
