Sodium flouride, NaF, is a basic salt. Write the chemical equation that describes how the salt breaks up into its ions. Write the chemical equation that describes how one of the ions behaves as abase in water to produce OH-.
Calculate the theoretical amount of 2.5 M NaOH (10%) solution needed to convert the benzoic acid to its water-soluble salt. Is the combined volume of NaOH used in the extractions sufficient for complete deprotonation of benzoic acid
Determine the theoretical volume of NaOH it should take to neutralize the sulfuric acid in the equilibrium reaction mixture.
A container holds 2,0 of gas. the total average change in KE of gas molecules in the container is equal to the the sum of KE of an 8,0x10^-3 -Kg bullet with speed of 770 m/s.
An ideal gas mixture contains 35% helium, 20% methane, and 45% nitrogen (by volume) at 2.00 atm absolute and 90 C. Calculate: (a) The partial pressure of each component
The concentration of N2O4 at equilibrium was 0.0750 M. Calculate Kc for the reaction, according to the above equation.
Large quantity of ammonia are burned in the presence of platinum catalyst to give nitric oxide as d first step in the preparation of nitric acid.
A chemist trying to synthesize a particular compound attempts two different synthesis reactions. The equilibrium constants for the two reactions are 23.3 and 2.2 x 10^4 at room temperature.
Potassium metal reacts violently when added to water according to the balanced equation: 2K(s) + 2 H2O (I) > 2KOH(aq) + H2(g). How many moles of H2O are needed to react completely with 7.54 mol of K
a solution is prepared by dissolving 2.33g of c60 in 100.0g of toluene. given that the vapor pressure of pure toluene
the concentration of a solution sodium iodide ion will be determined by titrating 90 ml of it using potassium
Given the values of ?Hfo in kJ/mol and So in J/mol K given below, calculate the value of ?Go in kJ for the reaction at 298 K.: NH4Cl(s) => HCl(g) + NH3(g) ?Hfo (NH4Cl) = -312.4 ?Hfo (HCl(g)) = -91.5 ?Hfo (NH3) = -44.5 So NH4Cl(s) = 93.9 So HCl(g) ..
The delta G for the freezing of H2O (l) at -10 degrees celsius is -210 J/mol and the heat of fusion of ice at this temperature is 5610 J/mol. Find the entropy change of the universe when 2 mol of water freezes at -10 C.
