Which of these processes does not require energy input? Transcription, translation, replication, synthesis of phospholipids, or do they all require energy?
the two amino acids, glycine and alanine, can form two different dipeptides. Draw one of the possible dipeptides as it would appear at a pH of 7. Be sure to include any necessary nonzero formal charges in your drawing
A 400.0 g block of aluminum at T=30 degrees Celsius is placed in contact with a 600.0 g block of iron at T= 100 degrees Celsius. Following heat transfer, what is the final common temperature of the two metal
Using the Ka values, calculate the pH of a buffer that contains the given concentrations of a weak acid and its conjugate bases. [1]. 0.86 M NaH2PO4 and 0.63 M Na2HPO4 [2] 0.60 M NaHCO3 and 0.72 M Na2CO3
Question- Nickel can be plated from aqueous solution according to the following half reaction. How long would it take (in min) to plate 29.6 g of nickel at 4.7 A? Ni2+(aq) + 2 e- --> Ni(s) 3.5*10^2 min
Predict the products of each of these reactions and write balanced molecular equations for each. If no reaction occurs
Explain what is the composition of the final solution when 26.5mL of 0.345 M HCL and 35.4mL of 0.510 M LiOH solutions are mixed
In the appropriate reaction conditions hydrogen and nitrogen react to form ammonia. If a reaction vessel primarily contained 500 hydrogen molecules and 150 nitrogen molecules, which molecules would stay after the reaction went to completion
explain why does atp synthesis occur in the presence of rotenone an inhibitor of one the reactions in the electron
When a molecule forms a hydrogen-bonded dimer as shown in your lab manual on pg 162 or is an electrolyte, you need to account for Van't Hoff factors. For the dimer shown in manual
15.0 mL of 0.50 M HCl is added to a 100.-mL sample of 0.496 M HNO2 (Ka for HNO2 = 4.0 × 10-4). What is the equilibrium concentration of NO2- ions?
Wish to detemine the reaction order and rate constant for the following thermal decomposition reaction 2AB2- -> A2 + 2B2 A) What data wolud you collect
(a) Calculate the minimum voltage required to produce 1 mole of aluminum at this temperature. (b) If the actual voltage applied is exactly two times the ideal value, calculate the energy required to produce 2.33 kg of the metal.
