A 100 g mass of tungsten at 100.0 °C is placed in 300 g of water at 20.0 °C. The mixture reaches equilibrium at 31.6 °C. Calculate the specific heat of tungsten. (specific heat of water = 4180 J/kg C)

What are transitions between a liquid and a solid called? identify which way they are transitioning

An object becomes electrically charged when: electrons are created in it electrons from it are destroyed electrons are transferred to it protons from it are destroyed protons are created in it

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.
