a. 0.0200 mol of sodium phosphate in 10.0 mL of solution
b. 0.300 mol of barium nitrate in 600.0 mL of solution
c. 1.00 g of potassium chloride in 0.500 L of solution
d. 132 g of ammonium sulfate in 1.50 L of solution.
Compute the binding energy of the 6Li nucleus in Joules per nucleon, given the subsequent nuclear masses: 6Li = 6.01348 amu, proton = 1.00728 amu and neutron = 1.00867 amu.
What it the chemical reaction between silver ion and excess ammonia.
calculate the amount of heat needed to boil 92g of ethanol beginning from a temperature of -69.2 c . be sure your
Condensation polymers are made using a monomer with two functional groups which split off as the remainder of the two monomers are joined together. Often the small molecule eliminated in the process is water
What is the millimolar concentration of dissolved oxygen for a lake or stream under the partial pressure of oxygen and a temperature of 12?
We most often express heat as kilocalories and kilojoules rather then calories and joules. When 1 pound of fat is burned in the body,9.4 kilocalories of energy is produced. Express that as a) calories b)kilojoules
Consider the fermentation of one molecule of glucose (Glc) to two molecules of lactate (Lac): Glc 2 Lac. Which of the following sets of concentrations would result in the largest release of free energy at 30°C
If 60.00 mL of water is added to 40.0 mL of 4.00 Molarity NaC1, what will the concentration of the new solution be
Determine the limiting reactant -reaction mixture initially contains no products
Why ammonium ion is NOT classified as a Bronsted-Lowry base? 2.Why sulfur hexafluoride DOES NOT obey the octet rule?
if 0.55 g of a gas dissolves in 1.0 l of water at 20.0 kPa of pressure, how much will dissolve at 110.0 kPa of pressure?
