Calculate the concentration of each reactant in trials 1 through 5 after the flasks contents have been combined but before the reaction takes place. (Basically need help finding the concentration for I, BrO3 and H for each trial using the given information below). Then determine the molarity of thiosulfate ion initiall present in the combined mixture
when filled with water (d=1.00 g/cm 3) the flask and it contents weigh 518.3 g. what is the flask's volume?
A solution is prepared by dissolving 19.9 g ammonium sulfate in enough water to make 100.0 mL of stock solution. A 15.00 mL sample of this stock solution is added to 59.00 mL of water.
Determine the ph ( to 1 decimal place) of a slution prepered by adding 125ml of 0.759M acetic acid to 10.3g of sodium acetate. the pKa of acetic asid is in table 10.2. Assume the volume of the solution does not change?
Using the moles of air, temperature of air and slope of the Air Volume vs. 1/pressure graph, calculate the ideal gas constant.
Calculate the number of moles of solute present in eahc other following solutions: a) 60.0g of an aqueous solution that is 1.25 percent KI by mass, b) 250g of an aqueous solution that is 0.460 percent NaCl by mass, c) 0.600L of 1.25M H2SO4.
A 15 L flask containing a sample of nitromethane is filled with O2 and the flask is heated to 100 celcius. At this temperture, and after the reaction is complete
32.5 kJ/mol°GD Muscles are powered by the hydrolysis of Adenosine tri phosphate determine Keq for this reaction
How would I do that? I have a diagram for a trigonal bipyramidal crystal field and two values are on the diagram. There's a delta 0.19 and a delta 0.79.
the red lice in the hydrogen spectrum is caused by the electron moving between which two energe levels? (the ionization energy of a hydroge atom is 2.18X10^-18J)
Explain using the Michaelis-Menten model the reasonsing behind the net effect of an irreversible inhibitor on the enzyme's substrate affinity and rate of product formation?
if you used 8900 kilojoules you expend in energy in one day to heat 49000g of water at 19 C what would be the rise in temperature.
