How do you find the limiting reactant in an equation? Also, why is the amount of grams of each reactant not the proper way to determine the limiting reactant?
A reverse osmosis unit is used to obtain drinkable water from a source that contains 0.570 g NaCl per liter. What is the minimum pressure (in torr) that must be applied across the semipermeable membrane to obtain water. Assume room temperature or ..
One liter of an acetate buffer is prepared by adding 60mL of 1.5M acetic acid and 50mL of 0.4M sodum acetate. Calculate the final concentrations of acetic acid and acetate
How low would the blood glucose concentration have to fall to decrease the rate of glucose phosphorylation in the erythrocyte to 90% of Vmax
The smallest unit of charge is -1.6× 10-19 C, which is the charge (in coulombs) of a single electron. Robert Millikan was able to measure the charge on small droplets of oil by suspending them between a pair of electrically charged plates.
An empty gasoline can with dimensions 15 cm by 40 cm by 12.5 cm is attached to a vacuum pump and evacuated. if the atmospheric pressure is 14.7 lb/in^2.
octane gas reacts wuth oxygen to form carbon dioxide gas and water as a gas. write balanced equation. how many grams of oxygen must react with 50 grams of hexane gas?
what is the enthalpy change for a reaction where the internal energy change is 58.0 kJ and the volume increase is 12.6 L? (1L * atm = 101.325 J)
Calculate the work(in kilojoules) done during a synthesis of ammonia(see reaction below) in which the volume contracts from 8.6L to 4.3L at a constant external pressure of 44atm. (Note: be careful what units you use, SI units needed) N2(g) + 3H2(g..
If there is a DBL bond do we always start on one with it even though the other bonds will be a higher number? and is that the same for triple bonds over dbl bonds
The molar enthalpy of vaporization of hexane (C6H14) is 28.9 kJ/mol, and its normal boiling point is 68.73°C. What is the vapor pressure of hexane at 25°C
which will precipitate first BaF2 (ksp= 1.7*10^-6) or Baso4 (Ksp=1.08*10^-10)? if the Ba2+ concentration is adjusted to 0.05M, what are the molar concentrations of F1- and So4 2- remaining in the solution
Why pure oxygen is often administered to victims of CO poisoning explain using le chatelier's principle. Hb (CO) aq + O2 aq is HbO2 aq + CO aq
