Write equations showing how each of the following weak bases ionizes water to form OH- a) HCO3- b) CH3NH2 Identify all of the phases
Calculate the approximate molarity of this solution from the volume, percent composition, and density.
How many milliliters of a solution that is 10.53% H3PO4 (w/w) with a density of 1.1928 g/mL should be diluted in order to make 4.50 L of a 0.100 M H3PO4 solution
Explain why it is important that the glassware and reagents used in a Grignard reaction are completely dry. Write an equation that describes what happens if phenylmagnesium bromide reacts with water.
CO(g)+2H2(g)->CH3OH(g) How many moles of each reactant are needed to produce 3.60 X 10^2g of CH3OH?
consider the following reaction: 2 A(g) + B(g) 3 C(g) + D(g) Please determine Kc if 6.0 moles of A is added to 6.0 moles of B in a 2.0 L yields 0.10 moles of D at equilibrium.
Recall "living" carbon samples show 15.3 d/min*g (carbon). note: CaCO3 is 12.00% carbon, and 14C has a half-life of 5730yr.
How many grams of hydrogen are collected in a reaction where 1.92 L of hydrogen gas is collected over water at a temperature of 40C and a total pressure of 738 torr.
