A titration is carried out to determine the concentration of the acid in an old bottle of aqueous HCl whose label has become unreadable.What is the HCl concentration if 32.1mL of 0.250M NaOH is required to titrate a 30.0mL sample of the acid?
Consider the reaction: Mg(s)+Fe2+(aq) -> Mg2+(aq)+Fe(s) at 63 degrees celsius, where [Fe2+] = 3.50M and [Mg2+] = 0.310M. The reaction quotient, Q, for the cell is 8.86x10^-2. The temperature, T, in kelvins is 336K.
2 NH3(g) + 3 O2(g) + 2 CH4(g) → 2 HCN(g) + 6 H2O(g) If 5.46x10^3 kg each of NH3, O2, and CH4 are reacted, what mass of HCN and of H2O will be produced, assuming 100% yield?
Calculate the standard enthalpy change, the standard entropy change, and the standard free energy change for the reaction: N2 (g) + 3 F2 (g) ? 2 NF3 (g) How will the sign of ?G change as the temperature increases
sample of sodium reacts completely with 0.142kg. of chlorine forming 234 g. of sodium chloride. what mass of sodium
If the pH of a 1.00-in. rainfall over 1600 miles^2 is 3.30, how many kilograms of sulfuric acid, H2SO4, are present, assuming that it is the only acid contributing to the pH. For sulfuric acid, Ka1 is very large and Ka2 is 0.012.
