The method of initial rates involves substituting the initial reactant concentrations into rate calculations. When you do the experiment, you will be given KMnO4 and H2C2O4 solutions of known concentrations. Will you use these known concentrations in your rate concentrations? Briefly explain.
A student collects 22.4 mL of a gas by the process of water displacement at a temperature of 0 °C. If the barometric pressure is 764.6 torr and the vapor pressure of water at 0 °C is 4.6 mmHg,
What are the seven redox reactions of these species of Mn2+?Mn2+ Mn(OH)2 (s) Mn3O4 (s) Mn2O3 (s) MnO2 (s) H2O H+ e-
a gas-filled balloon having a volume of 6.00 l at 1.2 atm and 25degc is allowed to rise to the stratosphere about 30 km

12.0 moles of gas are in a 3.00L tank at 22.7C. Calculate the difference in pressure between methane and an ideal gas under these conditions. The van der Waals constants for methane are a=2.300L^2*atm/mol^2 and b=0.0430 L/mol.
a 11.7 ml sample of a hcl solution has a ph of 2.000. what volume of water must be added to change the ph to
a 1.00 l sample of gas initially at 273 degrees c and 2.00 atm was cooled to 0 degrees c and the pressure changed to
What types of crystals are formed by the following solid elements and compounds: BF3 BN (NH4)CO3? In each case, state the types of forces among the particles
Calculate the entropy change resulting from an increase in temperature from 285 K to 350 K of H2O2 given Cp = A + BT + CT^2 Where A=34.25, B = 55.18 and C = -35.15.
If 10.6 kilograms of Al2O3(s) , 54.4 kilograms of NaOH and 54.4 kilograms of HF react completely, how many kilograms of cryolite will be produced. What is the total mass of the excess reactants left over after the reaction is complete
How many liters of CH4 (g), measured at 23.4C and 768mmHG, must be burned to provide the heat needed to vaporize 3.78 L of water at 100C? DeltaHcomb= -8.90x10^2 KJ mol CH4. For H2)(l) at 100 C, d= 0.958 g cm and deltaHvap=40.7KJ mol.
The change cannot be determined without more specific information. It will remain constant. It will decrease by a factor of 2. It will decrease by a factor of 4.
