ch if the probability that an event does not occur is 0.3, determine the probability that the event occur.
Chemistry Lab Question (Stoichiometry) Many problems in chemistry require you to identify which reactant is limiting and then calculate how many grams of product can be produced. Imagine you have a problem where you are given X grams of reactant A and Y grams of reactant B. These two reactants produce Z grams of product […]
Calculate the pH Calculate the pH of a 6.71 x10-2 M NaOH solution.
Vapor Pressure and Electrolytes The question asks: “Calculate the boiling point for a 1.10 m aqueous solution of FeCl2. Kb for H20 is .50 C/m. Normal boiling point of water is 100.0 C.” Delta Tb = .51C x 1.10 m = .561 100 + .561 = 100.561 C BUT FeCl2 is a strong electrolyte, right? […]
