Consider the titration of 100.0 mL of 0.100 M NaOH with 1.00 M HBr. Find the pH at the following volumes of acid added and make a graph of pH versus Va: Va = 0, 1,5,9, 9.9, 10. 10.1. and 12 mL.
An unknown sample (0.6855 g) containing KHP is titrated to the equivalence point with 9.75 mL of ).07892 M NaOH, How many moles of KHP present?
In an electron microscope the electrons generate the image. For one of the scanning electron microscopes in our Central Analytical Facility, the electrons are accelerated to have a kinetic energy of 200,000eV. Electrons with this kinetic energy ha..
What is the heat capacity of mercury if it requires 167 J to change the temperatures of 15.0g mercury from 25.0 Celsius to 33.0 Celsius
if a liquid has a density or 1.17 g/cm(3) and a mass of 3750 g calculate the volume?
Consider the following thermochemical equation: CH4(g) + I2(g) --> CH3I(g) + HI(g) Enthalpy Value = +23 kJ
Naturally occurring gallium consists of two isotopes. One of those isotopes is 71Ga with an isotopic mass of 70.9247050 amu and an abundance of 39.892%. What is the mass number of the other isotope
determine the original mass of liquid, G, that was placed in the container. (Ignore the volume occupied by the liquid in these calculations)
Why isn't HBrO a stronger acid than HBr. Doesn't the acid strength increase with the amount of oxygens.
Calculate k, Calculate also how long it would take for half of A to react. assume pseudo first order with k'=k[OH-], since [OH-] is in great excess.
If 5 moles of propane and 10 moles of oxygen are sealed in a container and burned, which reactant will be the limiting reactant, and how many moles of carbon dioxide will be produced?
If the pH probe was miscalibrated and reports the pH and reports the pH to be 1 unit higher than the true pH of the solution it is in, would the molar mass you report for the solid acid be higher than
