A 25.00 mL aliquot of iron solution was titrated to equivalence with 26.19 mL of 0.0215 M KMnO4. A procedure similar to the one in experiment 7 was followed. Calculate the moles of iron in the original volumetric flask.
The original volume (before the .406 mole C(g) begins to decompose) is 10.00L. What is the volume in the cylinder at equilibrium?
the actual yield of a reactant is 22 g and the theoreticaal yield is 25 g calculate the percentage yield
The amount of energy needed to heat 2.00 g of carbon from 50.0 C to 80.0 C is 42.6 J. what is the specific heat capacity of this sample of carbon.
Use the balanced redox reactions and the standard cell potential to predict the volume of hydrogen gas (at STP) required each month to generate the electricity needed for a typical house. Assume the home uses 1600kWh of electricity per month.
A certain weak base has a Kb of 7.80 × 10-7. What concentration of this base will produce a pH of 10.16
Describe the various strategies for the excretion of nitrogenous wastes employed in higher animals (chordates), both human and non-human.

Indicate how many electrons are transferred in the formation of one formula unit of product
The base solution was added to the acid solution but was not stirred while temperature measurement were not made: c.) Some of the base splashed out of the calorimeter while pouring:
the fact that the relative reactivity of C-H bonds of an alkane for free-radical chain halogenation is tertiary > secondary > primary?
The zinc content of a 1.45 g ore sample was determined by dissolving the ore in HCl, which reacts with the zinc, and then neutralizing excess HCl with NaOH
Given that the partition coefficient for a solute is K in a water-ether solvent extraction system, is it more effective to do one extraction with V mL of ether or three extractions with V/3 mL of ether
