The tungsten metal used for filaments in light bulbs is made by reaction of tungsten(VI) oxide with
hydrogen:
WO3(s) + 3 H2(g) → W(s) + 3 H2O(9)
The above reaction was performed and produced
3.34 g of tungsten.

How many moles of tungsten(VI) oxide were required to produce the 3.34 g of tungsten?

How many moles of hydrogen are required to produce the 3.34 g of tungsten

How many grams of tungsten (VI) oxide must you start with to prepare 3.4 g of tungsten? ( for WO3, MW=231.8

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.
