Explain what is the effect on the calculated molarity of the titrant if the endpoint is overshot passed in the standardization titration?
Assuming the mixture has the same specific heat (4.184J/goC) and density (1.00 g/cm3) as water, calculate the heat (in J) transferred to the surroundings
Reaction A B proceeds with H = - 25 kJ×mol-1; S = - 100 J×K-1×mol-1. Substance A was taken at the initial concentration 2 mM. Determine the concentrations of A and B after the reaction reaches equilibrium. Assume T = 298 K.
Using Henry's Law to calculate gas solubility If air contains 78% N2 by volume, what is the solubility of N2 in water of 25oC and 1 atm (Henry's constant kH for N2 in H2O at 25oC = 7 x 10-4 mol/L.atm)?
Exposure to high doses of microwaves can cause damage. Estimate how many photons, with a wavelength= 12cm, must be absorbed to raise the temp of your eye by 3.0 degrees Celsius. Assume the mass of an eye is 11g and its specific heat capacity is 4...
