Which of these processes does not require energy input? Transcription, translation, replication, synthesis of phospholipids, or do they all require energy?
how many equivalents of KBr moles of 0.00416 relative to acetanilide moles of 0.00381 are used in this reaction
Calculate the applied pressure necessary to inflate the alveoli with the surfactant, in units of Torr. By what factor has the addition of the surfactant changed the inhalation pressure
The solubility of benzoic acid in water is 5.9 g/100 mL at 100°C; 0.30 g/ 100 mL at 25°C; and 0.17 g/100 mL at 0°C. Can a mixture of approximately equal amounts of benzoic acid and salicylic acid be separated by recrystallization? Explain.

Question- Find the ph and concentrations of CO3^2-, HCO3^-, H2CO3 at the first equivalence point when 50ml of 0.150M carbonic acid is titrated with 0.120M NaOH. (pk1=6.351, pk2=10.329)
Using the same sample of gas (P 1= 795 torr , T 1 = 37 C ), we wish to change the pressure to 7950 torr with no accompanying change in volume or amount of gas. What temperature T 1, in Celsius, is needed to reach this pressure
Explain why if benzoic acid were substituted for 2-methoxyphenylacetic acid in this experiment the enantiomeric ratio of the yeast reduction product could not be determined by 1 H NMR.
A sample of NH4HS is placed in an evacuated container as well as allowed to come to equilibrium. The partial pressure of NH3 is then raised by the addition of 0.590atm of NH3. Explain the partial pressure of H2S at equilibrium is now what atm
In the presence of large excesses of I^-1 ion, the following set of data is obtained. What is the average rate of disappearance of H2O2(aq) in M/s in the first 45.0 seconds of the reaction if 1.00L of H2O2 reacts at 25C and 1.00atm pressure?
