This question is worth 20 points and there will be only one attempt. I will grade the first attempt of this question. Number your answers 1 through 10 and type the answers in the space provided. Consider the titration of a 35.0 mL sample of 0.185 M CH3NH2 with 0.150 M HBr. Kb = 4.4 x 10-4 What is the initial pH of the solution before adding the acid? What is the pH after adding 5mL of acid (before equivalence point)? What is the concentration of hydroxide ions at equilibrium before acid is added? At the equivalence point, what ion is affecting the pH? How many moles of acid needs to be added to reach the equivalence point? How many mL of acid needs to be added to reach the equivalence point? What is the percent dissociation of the weak base? What is the pH at the equivalence point? What is the pH after the addition of 47 mL of acid to this solution? What ion is affecting the pH after the addition of 47 mL of acid?

Ican determine the molar mass of an element by looking on the under the atomic mass for the element. for example the molar mass of phosphorus is 30.974 grams/mole. avogadro’s number tells me the amount of representative particles in 1 mole of any substance. this means 12.011 gram sample of carbon and a 32.0 gram sample of sulfur have the same number of atoms.

The allotropes of carbon include a variety of structures that include three-dimensional tetrahedral lattices, planes of hexagonal rings, cylindrical tubes of hexagonal rings, and spheres of five- and six-membered rings. similar shapes of network covalent atomic solids are possible with carbon nitride, boron, and pure silicon (e.g., silicene is a graphene-like allotrope of pure silicon). in contrast, silicates exist as either highly ordered or amorphous (more random) three-dimensional lattices. what could explain why there are there no naturally occurring sheets, stacked sheets, cylindrical tubes, or spheres of network covalent atomic solids composed of silicon and oxygen (sio2)? would pure silicate structures make good lubricants or good electrical conductors?
