What is the theoretical yield of calcium carbonate if 2.05 grams of calcium chloride dihydrate reacts with excess sodium carbonate according to the balanced chemical reaction shown below?
Balance the following half-reaction in base, using smallest whole number coefficients. What is the coefficient for OH- in the balanced equation?
What is the molarity of the prepared naoh solution as determined in the titration? How many moles of OH are present when the end point is reached? What color should the solution appear at end point?
Compare the volume of 1.0 g of bromine, Br2, as a solid, liquid, and gas. The density of solid bromine just below the melting point of -7°C is 3.2 g/mL, of liquid bromine at 25°C is 3.1 g/mL.
