A sample of 0.0020 mole of HCl is dissolved in water to make a2000-mL solution. Calculate the molarity of the HCl solution,the [H3O+], and the pH. For a strong acid such as HCl, the[H3O+] is the same as the molarity of the HCl solutions.HCl + H2O - - > H3O+ + Cl-
H2 and Cl2 combine to form HCl. In a gas phase equilibrium mixture of H2, Cl2, and HCl at 300 K, [HCl] = 0.0036 mol/L and [Cl2] = 0.00485 mol/L.
A 180 kiln is used for vitrifying ceramics. It is currently operating at 1025 , and the pressure is 1.100 . How many moles of air molecules are within the confines of the kiln.
what will be the final temperature in degrees Celsius If the volume of a gas container at 32.0°C changes from 1550 mL to 755 mL,?
58.0 mL of a 1.30 M solution is diluted to a volume of 228 mL. A 114-mL portion of that solution is diluted using 141 mL of water.
The gas phase irreversible first-order reaction A----> 3B , is carried out in PFR where the feed is equal molar in A and inerts. the conversion under these circumstances is 50%.
In the reaction MnO4- + 8H+ + 5e- ⇔ Mn2+ + 4H20, the manganese in 3.95 grams of KMnO4 is reduced to Mn2+. How many coulombs of charge must have been transferred to the permanganate ion.
Determine the mechanism for the synthesis of p-nitroacetanilide from acetanilide and HNO 3 , nitric acid and H 2 SO 4 sulfuric acid?
Compute the boiling point of this solution if Kf and Kb for H 2 O are given as 1.86°C/m and 0.512 °C/m , respectively.
If it takes 34.0 mL of 0.0250 M K2Cr2O7 to titrate 10.0 mL of a solution containing Fe2+, what is the molar concentration of Fe2+.
