The osmotic pressure of blood at 27 degrees Celcius is 7.7 atm. A solution that is given intravenously must have the same osmotic pressure as the blood. What should be the molarity of an aqueous solution of glucose ( which is a non-electrolyte) to give an osmotic pressure of 7.7 atmm at 37 Celcius.
Draw both extended and Fischer representation of each of these compounds.
If the average speed of an oxygen molecule is 4.05multiplied by 104 cm/s at 25°C, what is the average speed of a CO2 molecule at the same temperature?
A 352-mL container of nitrogen is held at a pressure of 791 mm Hg. What volume container would be lowered to 649 mm Hg?
Benzene, C6H6, is reacted with bromine, Br2, to produce bromobenzene, C6H5Br, and hydrogen bromide, HBr, as shown below. When 40.0 g of benzene are reacted with 95.0 g of bromine, 65.0 g of bromobenzene is produced.
The decomposition of potassium chlorate (KClO3) is used as a source of oxygen in the laboratory. How much potassium chlorate is needed to produce 20.7 mol of oxygen?
My lab is of an iodine clock reaction. I am being asked to calculate the initial rates for experiments 1, 2, and 3 from delta [S2082-]/ delta time. I know how to use the initial rate method however I am confused on how to obtain the initial concen..
Kc = 9.7 at 900 K for the reaction NH3(g) + H2S(g) --> NH4HS(s) If the initial concentrations of NH3(g) and H2S(g) are 2.0 M, what is the equilibrium concentration of H2S(g)?
spontaneous chemical reactions produce products which are more energetically stable than the reactants which form them. A strong acid reacts with a strong base to produce water and the free ions of a salt.
Calcium phosphate, silicon dioxide, and coke may be heated together in an electric furnace to produce phosphorus, as shown in the following equation: 2Ca3(Po4)2+6SiO2+10C=6CaSiO3+10CO +P4
calculate the molecular mass of a solute with 8.02 grams of solute in 861 grams of water lower the freezing point to -.430 degree Celsius
The flask was then shaken until the solution was uniform. A 25.0-mL sample of this glucose solution was diluted to 0.500 L. How many grams of glucose are in 100. mL of the final solution?
