For a classroom demonstration a chemistry teacher puts 5 mL of water into a soft plastic pop bottle and with tongs, holds it in a hot water bath for 1 minute. The teacher removes the bottle and tightly screws on the cap.
The equilibrium concentration of I2 is 0.0900M. What is the equilibrium constant, Kc , for the reaction at this temperature?
Prepare a chemistry lab report about burning a peanut. Your results are expected to be lower due to heat losses. If you got 12,500J/g, it is (12,500/24,500)*100%= 51.0% of the jar value.
How much energy is released per Kg of Dilithium formed? Mass of one atom of 6 Li is 6.015121 amu. Do not know where to start.

A sample of 2-butanol has a specific rotation of +3.25. Determine the %ee and the molecular composition of this sample. The specific rotation of pure (+)-2-butanol is+13.0.
calculate the change in entropy (?S), the change in internal energy (?U), and the change in enthalpy (?H) for a reversible adiabatic expansion of this gas to a final pressure of 1.10 atm. Also calculate the final temperature (T) and volume (V).
Determine the flow is turbulent or streamline when the inside pipe diameter is 2.0 inches and the absolute viscosity of the fluid
Compute the pH for each of the subsequent cases in the titration of 25.0mL of 0.190 M pyridine, C5H5N(aq) with 0.190 M HBr(aq)
Draw the skeletal structure of the product if the following alcohol were treated with HF in pyridine. Atoms other than carbon and hydrogen are labeled
Which of the following pairs of molecules is listed in order of decreasing net dipole moment (from more polar molecule to less polar molecule)? A. SiCl4 > SCl4 B. PF3 > PH3 C. H2S > H2O D
Many elements can have more than one charge or oxidation number. In this set of problems, we will assign oxidation numbers to each atom in sulfate, carbonate, bicarbonate, bisulfate, sulfite, nitrate, nitrite, chlorate, and perchlorate.
