During a lab do not worry about what other students are doing around you, just focus on your own area.

What should you maintain in your lab work area?

What should you NEVER do if you have heated a container?

Always wash your hands after handling chemicals.

Consider an aqueous solution containing 3.6 x 10-10 M H3O+. Calculate the [OH-] in M. Show your solution in your scratch paper that needs to be uploaded. No solution no points. Observe significant figure rules. Example of entry: 1.65 x 10^(-14) Bonus: indicate in your paper if this is acidic or basic (3 pts)

Write a notation for electrochemical cell. Use any example we discussed in the class. Also. write the oxidation and reduction half reaction from the cell notation.

Consider a 0.010 M Sr(OH)2, calculate the pH of this solution. Show your solution in your scratch paper that needs to be uploaded. No solution no points. Observe significant figure rules.

The Haber-Bosch process is the main industrial route to production of ammonia and is written as: N2(g) +3H2(g) ↔ 2NH3(g) with a ΔH° for the reaction being -92.4 kJ/mol. How would a decrease in the volume of the container affect the equilibrium ? Which direction, if any, will the reaction go to re-establish the equilibrium?

If I mix an equimolar (same amount of moles) amount of a weak acid (HCN) and a strong base (NaOH), what will be the pH of the combined solution after the reaction (pH >, < or = 7) ?   

Kc is equal to 0.28 for the following reaction at 900 °C: CS2(g)+4H2(g) ⇌ CH4(g) + 2H2S(g) What is KP at this temperature?
