A, tính tỉ khối của hỗn hợp A gồm 0,5 mol O2 và 1,5 mol N2 so vs không khí b, hỗn hợp chứa 3 khí N2, H2,NH3 có tỉ khối đối vs không khí là 0,47. tìm % thể tích mỗi khí trong hỗn hợp. Biết mol H2 = 3 mol N2

Calculate: select the worksheet tab. this tab you calculate the analyte concentration.  fill in the first set of boxes ("moles h2so4" and "moles naoh") based on the coefficients in the balanced equation. (if there is no coefficient, the value is 1.)  record the appropriate volumes in the "ml naoh" and "ml h2so4" boxes.  record the concentration of the titrant in the m naoh box. click calculate. what is the concentration listed

The mass of a neutron is equal to the mass of a proton plus the mass of an electron. true or false false true

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.
