A student determined the freezing point of pure t-butyl alcohol following the procedure given in this experiment . Because of an experimental error, the freezing point temperature that she obtained was higher than the correct value. Explain whether this error will lead to values of each of the following quantities that are larger or smaller than the correct values.
A. Freezing point depression of salicylic acid soultion in t-butyl alcohol?
B. freezing point depressin constant of t-butyl alcohol?
In the decomposition of hydrogen peroxide, the percentage yield of oxygen is 93%. What is the actual yield in grams of oxygen if you start with 100 grams of H2O2.
Substances A2, B2, and C2 can act as oxidizing agents. Solution A2 is green, B2 is yellow, and C2 is red. In the reactions in which they participated they are reduced to A-, B-, and C- ion, all of which are colorless
The NaHCO3 is the limiting reactant and the HCl is the excess reactant in this experiment. Determine the theoretical yield of the NaCl product.
Research the number of electrons that can fit into energy levels higher than the third level. Why does that explain why there is a space in the lower periods of the periodic table?
A 2kg iron bar (c of iron is 440 J.kg .K) is heated to 80 Celsius. The bar is dipped in 5kg of water at 20 Celsius in a heat insulated container. What will be the equilibrium temperature inside the container?
A 11.0-L helium tank is pressurized to 26.0 atm. When connected to this tank, a balloon will inflate because the pressure inside the tank is greater than the atmospheric pressure pushing on the outside of the balloon.
Titrations: Finding Concentration, A 35.00 mL solution containing an unknown concentration of pyruvic acid required 25.13 mL of 0.2011 M NaOH to reach the end point.
Clearly indicate coordinate system used in finding the answer. Basically trying to work up to building the molecular orbital diagram. I am stuck in the step where you determine the transformation sequences of each symmetry subset.
