Energy from atp hydrolysis drives many nonspontaneous cell reactions: atp4-(aq) + h2o(l) adp3-(aq) + hpo42-(aq) + h+(aq) = -30.5kj energy for the reverse process comes ultimately from glucose metabolism: c6h12o6(s) + 6o2(g) → 6co2(g) + 6h2o(l)a. find k for the hydrolysis of atp at 37˚c. b. find for metabolism of 1 mol of glucose. c. how many moles of atp can be produced by metabolism of 1 mol of glucose? d. if 36 mol of atp is formed, what is the actual yield?

Astudent is given a sample of a blue copper sulfate hydrate. he weighs the sample in a dry covered porcelain crucible and got a mass of 23.875 g for the crucible, lid, and sample. the mass of the empty crucible and lid was found earlier to be 22.652 g. he then heats the crucible to expel the water of hydration, keeping the crucible at red heat for 10 minutes with the lid slightly ajar. on colling, he finds the mass of crucible, lid, and contents to be 23.403 g. the sample was changed in the process to very light clue anhydrous cuso4. if there are again 100.0 g of hydrate, how many grams of cuso4 are in it? how many moles of cuso4? (hint: molar mass of cuso4 = 159.6 g / mole. what per cent of the hydrate is cuso4? you may convert the mass of cuso4 to moles.)

21. consider the following chemical reaction: n2+ o2 2 no if 10.0 g of n2 reacts with excess oxygen then how many grams of no can be formed? a) 10.7 g b) 21.4 g c) 32.9 g d) 42.8 g page 4 of 8

Jose and eric were given four samples in lab. the results of their analysis are shown in the table. based on the data they collected, which sample is most likely a metal?
