2) A student performed the titrations done in this experiment. The student pipetted 25mL of solution that contained saturated calcium hydroxide solution and 0.05 M calcium ions into a flask and then titrated it with 0.103 M HCl. It required 2.77mL of HCl to reach the orange-red end point. Calculate the molar solubility of calcium hydroxide in this solution.

Urea, co(nh2)2, is manufactured on a large scale for use in producing urea-formaldehyde plastics and as a fertilizer. what is the maximum mass of urea that can be manufactured from the co2 produced by combustion of 1.00 x 104 grams of co2?

What happened in 2012 and how does it illustrate the importance of understanding the sun and how it works?

Consider the reaction of a(g) + b(g) + c(g) => d(g) for which the following data were obtained: experiment initial [a], mol/l initial [b], mol/l initial [c], mol/l initial rate, mol/l. s 1 0.0500 0.0500 0.0100 6.25 x 10^-3 2 0.100 0.0500 0.0100 2.50 x 10^-2 3 0.100 0.100 0.0100 1.00 x 10^-1 4 0.0500 0.0500 0.0200 6.25 x 10^-3 what is the rate law for the reaction?
