A student has spilled some acid onto their arm. One lab partner suggests pouring some base on it to neutralize the acid but the TA quickly interjects that would be a bad idea and has the student begin washing their arm
In an experiment conducted last Tuesday, the time it takes for a certain reaction to proceed seems to be related to the initial concentration of one of the reactants A.
The reactant concentration in a zero-order reaction was 8.00×10-2 after 100 and 4.00×10-2 after 370 .
A solution of ethanol (C2H5OH) in water is prepared by dissolving 63.0 mL of ethanol (density = 0.79 g/cm3) in enough water to make 255.0 mL of solution. What is the molarity of the ethanol in this solution?
