The concentration of CO2 in a soft drink bottled with a partial pressure of CO2 of 6.5 atm over the liquid at 29°C is 2.2 × 10-1 M. Determine the Henry's law constant for CO2 at this temperature.
in an experiment similar to the empirical formula experiment in the lab book a student reacted beryllium and oxygen
Compute the hydroxide ion concentration in a NH 3 solution that is 0.091 M and 0.028 M NH 4 Cl. Kb of NH 3 is 1.8 x 10 -5 .
Extraction procedures have shown that nitrogenase contains an iron-sulfur cluster, Fe4S4, where the atoms of each type are arranged alternatively at the corners of a cube.
The difference between a law and a theory is the difference between what and why. Explain.
What is the specific heat of aluminum if the temperature of a 28.4 g sample of aluminum is increased by 8.1 oC when 207 J of heat is added.
A 0.250 gram chunk of sodium metal is cautiously dropped into a mixture of 50.0 grams of water and 50.0 grams of ice, both at 0 degrees Celsius. The reaction is 2Na(s)+2H2O(l) yields 2NaOH(aq)+H2(g) enthalpy=-368 KJ. Will the ice melt? Assuming th..
What volume of a 0.1 M ClO- solution reacts stoichiometrically with a 10 mL solution of 0.2 M CrO2-? Use the reaction 2 CrO2- + 3 ClO- --> 2 CrO4-2 + 3 Cl- to assist in the calculation.
