A new solid Ni(II) octahedral complex has been synthesized containing only chloride and ammonia as ligands. When 9.64x10-4 moles of this complex is dissolved into 425.0 mL of the water, you find that 19.22 mL of 0.1000 M HCl is needed to reach a titration endpoint. What is the final formula? (Make sure that your final formula contains the necessary counter ions to make a neutral salt)
Trans-1-bromo-2-methylcyclohexane reacts under E2 conditions to give a single elimination product. What is this product and explain how it is formed by conformational analysis.
you reacted 11.5 grams of sodium sulfate and 55.0 ml of 0.500 M barium nitrate, how many grams of barium sulfate are made.
if you are limited to two significant figures in your determination of the molar mass, what could you do to increase the precision of the experiment to 3 sig fig. What consequences would this have
a gas sample has an original volume of 760 ml when collected at 720 mm and 25degc. what will be the volume of the gas
NH3 is a weak base (Kb=1.8 x 10^-5) and so the salt NH4Cl acts as a weak acid. What is the PH of a solution that is 0.049 M in NH4Cl?
Calculate the molarity (M) of the following solutions. Express the answer using 2 sig figures.
A 500 mg tablet of antacid (all 500mg is calcium carbonate) is put into 250 ml of 0.12M hydrochloric acid. What volume of gas is produced at STP and how many moles of excess H3O+ are left over
a swimming pool 20.0m 12.5 is filled with water to a depth of 3.81m. if the initial temperature of water is 17.5c how
what volume of 0.240 m cacl2 must be added to 335 ml of 0.189 m kcl to produce a solution with a concentration of 0.245
Redox titrations are used to determine the amounts of oxidizing and reducing agents in solution. For example, a solution of hydrogen peroxide,H2O2 , can be titrated against a solution of potassium permanganate,KMnO4
Would applying a high pressure stabilize the CsCl form, or the NaCl form of this compound? (hint: calculate the volume per formula unit)
why is it important to standardize NaOH solution instead of taking an accurate and diluting it in a volumetric
