Brandon is trying to remember how the physical and chemical properties of metals, nonmetals, and metalloids compare. he wrote some notes down, then looked in his textbook to see which notes were correct. which of brandon's notes, listed below, are correct? i. metals are the best at conducting heat, and nonmetals are the worst. ii. metals are the worst at conducting electricity, and nonmetals are the best. iii. the shape of nonmetals is easy to change, but the shape of metals or metalloids is difficult to change. iv. nonmetals are dull in appearance while metals are usually shiny. v. metals tend to have a high density, and nonmetals tend to have a low density. a. i, ii, iii, iv, and v b. i, iv, and v only c. i, ii, and iii only d. ii, iii, and v only

5submission this assignment is worth 20 points total. you are required to submit the following by next lab: 1. (3 points) determine the equation for the output angular velocity ω2 = θ˙ 2 as a function of θ1, ω1 = θ˙ 1 and α. you must show all your work to receive credit. 2. (2 points) use the result of problem#1 to plot ω2 over 0 ≤ θ1 ≤ 360deg with ω1 = 360deg/sec. do this for α = {10,30}deg. show the results on the same plot and properly label the axes, title, legend. for this you can use matlab or ms excel. 3. (3 points) determine the equation for the output angular acceleration ω˙ 2 and create a plot similar to the one in problem#2. 4. (10 points) submit plots of the results (ω2 and ω˙ 2) obtained from creo/mechanism and compare them to results of problem#2 and problem#3. note that you should do these comparisons for the two cases with α = {10,30}deg. 5. (2 points) provide a brief explanation of the results. did they match? what are the implications as misalignment angle increases?

The vapour pressure of benzene is 53.3 kpa at 60.6 °c, but it fell to 51.5 kpa when 19.0 g of a non-volatile organic compound was dissolved in 500 g of benzene. calculate the molar mass of the compound.

He latent heat of vaporization for ethyl alcohol is 854 j/g. the amount of energy, rounded to the nearest whole number, needed to change 5.20 grams of ethyl alcohol from a liquid to a gas is
