Calculate the distances NH3 gas and HCL gas would travel in this experiment if a 100.00-cm tube were used, based on the accepted molar masses of the two gases.
After treating an antacid with 5.00 ml of .1065 M NaOH, the untreated acid was diluted to exactly 250 mL with distilled water in a volumetric flask. 25.00 mL of that diluted acid required 17.03 mL of the same NaOH solution to neutralize it. Calcul

Will the temperature decrease shift the equilibrium toward the reactants or products for a reaction characterized by a positive reaction enthalpy and positive reaction entropy?
How much N2 will be produced (L) when 6 liters of a C6H12O6 solution is degraded to CO2 and H2O? The concentration of C6H12O6 solutions is 200 mg/L.
Complete and balance the following equation: BrO3^-(aq)+N2H4(aq) -> Br2(l)+N2(g) And identify the oxidizing and reducing agents from the resulting balanced equation.
Although it is not an ionic solute, a 1.00-molal solution of ammonia, NH3, is actually a weak electrolyte and has an ionic strength of about 1.4 x 10^-5 molal. Explain.
How many milliliters of 0.100 mol of KOH solution are needed to completely neutralize the HCl in 300 mL of a hydrochloric acid solution that has a pH of 2.25?
The broad features of the spectrum are thereforeexpected to resemble those of hydrogen, the differences arising largely from the mass relations. At which energy will the first three lines of the Balmer series of positronium appear?
