The heat capacity, c p , of liquid carbon disulfide is a relatively constant 78 j / ( mol ⋅ k ) . however, the heat capacity of solid carbon disulfide varies greatly with temperature. from 99 k to its melting point at 161 k , the heat capacity of solid carbon disulfide increases linearly from 44 j/ ( mol. k ) to 57 j / ( mol. k ). the enthalpy of fusion of carbon disulfide is δhfus = 4390 j/mol . the absolute entropy of liquid carbon disulfide at 298 k is s = 151 j / ( mol. k). estimate the absolute entropy of carbon disulfide at 99k .

When a comet collides with earth, it adds material to our planet and causes great damage. therefore, a collision like this is a a. destructive force b. constructive force c. geologic process and event d. constructive and destructive force

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.

Kp is the equilibrium constant for dissociation of the propionic acid dimer. what is the sign of the slope for a plot of the natural logarithm of kp vs. inverse temperature for this reaction?
