Write a balanced chemical reaction for photosynthesis (accounting for both the light and dark reactions). Compare the pathways of photosynthesis and oxidative phosphorylation. Identify specific molecular components that are similar and different between these two pathways.
A bottle of 5.5 M acid has 21.3 mL remaining in it. If the acid is diluted to 700 mL, what is the new concentration of the acid?
calculate the minimum number of grams of C3H8(g) that must be combusted to provide the energy necessary to convert 2.93 kg of H2O from its solid form at -13.0°C to its liquid form at 75.0°C.
What is the final temperature when 150 mL of water at 90,0 C is added to 100.0 mL of water
How much ethylene glycol (C2H6O2) the major component of antifreeze, must be added to 1 L of water to keep it from at -15 F? Kf= 1.86 C/m.
Calculate the pH of a buffer solution that is 0.250 M in HCN and 0.170 M in KCN. For HCN, Ka = 4.9 x 10^-10 (pka = 9.31). Use the equilibirum approach to calculate
Consider the situation in which 1.60 mL of an aqueous CuSO4 solution of unknown concentration is diluted to a volume of 10.00mL.
Aluminum will act as the stronger reducing agent and iron will act as the stronger oxidant. In the spontaneous reaction, the oxidation number of iron will increase.
NaOH is added to 625 mL of 0.250 M weak acid (Ka = 5.62 × 10-5). What is the pH of the resulting buffer?
We have a refrigeration unit that works at a pressure of 0.1MPa in the evaporator and 1 MPa in the condenser. The refrigeration unit uses a compressor with an efficiency of 90% and a turbine with 100% efficiency is used to expand the refrigerant a..
