Assign an oxidation state to each atom in each polyatomic ion. Express answers as a signed integer. 1. CrO4^2- 2. Cr2O7^2- 3. PO4^3- 4. MnO4^-
The equilibrium constant Kc equals 1.6 10-2 at 200°C. What are the moles of substances in the equilibrium mixture at 200°C if we start with 0.021 mol HBr in a 1.3-L vessel?
A fixed amount of gas at 25.0 °C occupies a volume of 9.23 L when the pressure is 629 torr. Use Charles's law to calculate the volume (L) the gas will occupy when the temperature is increased to 121 °C while maintaining the pressure at 629 torr.
An iron bar of mass 781 g cools from 94°C to 5°C. Calculate the heat released (in kilojoules) by metal.
Calculate the sample weight of liquid bleach containing 5.0% by weight of NaOCl that would oxidize enough I- to consume 0.80 mL of 0.15 M sodium thiosulfate.
When numbers are very small or very large, it is convenient to either express the value in scientific notation and/or by using a prefix with the unit.
For the titration of 30.00 mL of 0.5000 M acetic acid with 0.5000 M NaOH, calculate the pH before you add the NaOH a) before the addition of any NaOH solution.
Imagine that you have a 6.50L gas tank and a 2.50L gas tank. You need to fill one tank with oxygen and the other with acetylene to use in conjunction with your welding torch.
Chlorine gas can be prepared in the laboratory by the reaction of hydrochloric acid with manganese(IV) oxide: 4HCL(aq) + MnO2(s) ----> MnCl2(aq) + 2H2O(l) + Cl2(g)
Cyclohexyl carbocation undergoes attack by nucleophiles. With this in mind, propose a mechanism whereby cyclohexene might form the dimer 31 in the presence of H3O+. Note that this type of reaction leads to polymerization of cyclohexene.
The moles of salicylic acid is 0.00724mol. The molar mass is 138.12 salicylic acid . Given 1.00 g of salicylic acid . Please show work? m=mol of solute X particles per formation/ mass of solvent, kg
Showing dU/dV at constant T = 0 using Maxwell relationship? No need to solve through the whole thing, just relate equations and calculus identity that I may need.
The ozone in the ozone layer absorbs UV light between 200 and 300 nm. Ozone is a compound with the chemical formula CO2. In the Earth's atmosphere, ozone exists only in the ozone layer.
