Calculate the concentration given the absorbance. Each test tube has 5ml of water then a certain amount of bromol blue. 1 ul bromol blue absorbs at= 0.092, 2 ul=0.105, 4ul=0.093, 10=0.199, 20= .225, 30= 0.592, 50=0.957, 100= 1.717. All absorbances measured at 540 nm. I have been told that I need to use C1V1=C2V2 but I have no idea how.
Explain how a competitive inhibitor inhibits an enzyme and how the effect is different from that of an irreversible inhibitor.

calculating the pH of the final solution at equivalance point. Please show a step-by-step process
From the understanding of colligative properties, how would I design an experiment to measure the freezing point of a material which freezed at -2'c using the same apparatus used in the laboratory and any chemical reagents commonly found in a chem..
Suppose the reaction Ca3(PO4)2 + 3H2SO4 ------ > 3CaSO4 + 2H3PO4 is carried out starting with 103 g of Ca3(PO4)2 and 33.7 g of H2SO4. How much phosphoric acid (H3PO4) will be produced?
Calorimetry is a method used to measure enthalpy, or heat, changes that occur during chemical processes. Two common calorimeters are constant-pressure calorimeters and constant-volume (or "bomb") calorimeters
If we have benzene, acetyl chloride, AlCl3 and HCl in a solution of NaoH and CH2Cl2 which of these will be in the NaOH layer and Which of them will be in the CH2Cl2 layer
Calculate the pH at the equivalence point for titrating 0.170 M solutions of each of the following bases with 0.170 M HBr. a)sodium hydroxide
For each reaction, identify the acid-base conjugate pairs. Then rank all reacionts in order of increasing tendency for the reaction to go to completion (to the right)
A football is inflated to a pressure of 1.00 x 10^3 torr in a room at 25 degrees C. If the game is played at 10 degrees C, what will the pressure in the ball be, neglecting any volume change in the ball and assuming that it doesn't leak?
