A student prepares a solution of carbonate-free NaOH. Upon drama a rough titration, the student finds the concentration to be 0.0673 M instead of 0.1000 M. presuming that the volume of the solution is 950.0mL, explain how many grams of sodium hydroxide should be added to the solution to produce a concentration as close as possible the desired 0.1000 M? Presume that the sodium hydroxide is carbonate-free.
With a slope of 5.5x106 m3/K, 1 mole, and 273.15K explain what is the coldest temperature that liquid water exists using the Clapeyron equations
Hydrazine (N2H4) is a fuel used by some spacecraft. It is normally reacted with N2O4 according to the equation: N2H4(l) + N2O4 (g) 2 N2O(g) + 2 H2O (g) a) Identify the oxidizing agent and the reducing agent in the reaction
