In photosynthesis, plants use energy from the sun in combination with carbon dioxide and water to form glucose (C6H12O6) and oxygen. If 4.50 moles of water react with carbon dioxide, what mass of glucose is produced?
Radiation with a 58.4 nm of wavelength interacts with a H 2 (hydrogen atom)and induces the ejection of an electron then determine the kinetic energy of the departing electron express your answer in eV?
Concrete used in road construction is reinforced using steel bars in a grid, known collectively as "rebar." After many years, rebar will begin to corrode, and the concrete will weaken.
A stock solution is prepared by adding 10 mL of 2.5 M Ba(CN)2 to enough water to make 23 mL. What is the CN- concentration of 5 mL of the stock solution
A mixture of O2, CO2, and N2 has a total pressure of 697. torr. In this mixture the partial pressure of O2 is 143. torr and the partial pressure of CO2 is 197. torr. What is the partial pressure of the N2 (in torr)?
Acetylene gas (C2H2) is produced by adding water to Calcium carbide CaC2. How many grams of acetylene are produced by adding water to 5g CaC2?
Compute the number of rads and rems of radiation in five years from such a level of plutonium.
53.0 mL of a 1.70 M solution is diluted to a volume of 278 mL. A 139-mL portion of that solution is diluted using 189 mL of water.
A piece of sodium metal reacts completely with water as follows. 2 Na(s) + 2 H2O(l) 2 NaOH(aq) + H2(g) The hydrogen gas generated is collected over water
An aqueous solution is 22.0% by mass silver nitrate, AgNO3, and has a density of 1.22 g/mL. What is the molarity of silver nitrate in the solution?
Explain why does ATP synthesis occur in the presence of Rotenone ( an inhibitor of one the reactions in the electron transport system.) if succinate is combined but not ATP synthesis doesn't occur if L-malate is added?
A 115 mL sample of a 11.0 M ethylene glycol (rm C_2H_6O_2) solution is diluted to 1.40 L.What is the freezing point of the final solution? (Assume a density of 1.06 g/mL for the final solution.)
A sample of hydrogen gas was collected over water at 36°C and 855 mm Hg. The volume of the container was 6.50 L. Calculate the mass of H2(g) collected. (Vapor pressure of water = 44.6 torr at 36°C)
