What is the magnitude of the average acceleration of a skier who, starting from rest, reaches a speed of 11.8 m/s when going down a slope for 3.61 s? (b) How far does the skier travel in this time
Calculate how many calories of heat are needed to increases the temperature of 550 grams H2O from 12 degree celsius to 18 degree celsius?
Describe what will be observed when a mixture of composition x_b=0.8 is heated, at each stage giving the number, composition, and relative amounts of the phases present.
Calculate the masses of (a) KNO3 and, separately, (b) Ba(NO3)2 to add to a 0.110 mol kg^-1 solution of KNO3(aq) containing 500 g of solvent to raise its ionic strength
What is the de Broglie wavelength of a 145 g baseball traveling at 30.0 m/s (67.1mph)? Is the wavelength much larger or smaller than the diameter of an atom .
Chemists often use molarity ,M in Moles/liter , to measure the concentration of solutions. Molarity is a common unit of concentration because the volume of a liquid is very easy to measure
Assume for simplicity that the volume of the mixture is exactly equal to the sum of the volumes of the ingredients (which is not true, by the way). What is the mass concentration of oxygen in the mixture?
What is the bond order of a molecule with 10 valence electrons 12valence electrons,13 valece electrons,14 valence electrons
What is the mole fraction of solute and the molal concentration for an aqueous solution
in a strongly acidic solution the amino acid lysine esists as the dication. as the pH is raised, what monocation is formed by the loss of a proton form the dication?
A L flask is filled with 1.35 g of argon at 25 C. A sample of ethane vapor is added to the same flask until the total pressure is 1.45 atm.
solution requires 14.45 mL of 1.00 M NaOH for titration. How many molesof HCl are present in the solution? The density of 3 M HCl is 1.05 g/mL
