PLEASE HELP Read the directions and create the graph described below. You will then click the submit button and upload a picture of your graph or some sort of digital version of your graph. It could be done 1) using a computer program or 2) hand drawn, photographed, and submitted. You are to create a graph with horizontal and vertical axis. Label "Pressure" on the horizontal axis from O mb to 760 mb. Label "Volume" on the vertical axis from O to 1 mL. Assign values to axes divisions in such a way that you occupy almost all the space on both axes. Now, locate and label the following points: (90, 0.9) (100, 0.8) (400, 0.2) (600, 0.15) (760, 0.1)

Astudent is given a sample of a blue copper sulfate hydrate. he weighs the sample in a dry covered porcelain crucible and got a mass of 23.875 g for the crucible, lid, and sample. the mass of the empty crucible and lid was found earlier to be 22.652 g. he then heats the crucible to expel the water of hydration, keeping the crucible at red heat for 10 minutes with the lid slightly ajar. on colling, he finds the mass of crucible, lid, and contents to be 23.403 g. the sample was changed in the process to very light clue anhydrous cuso4. if there are again 100.0 g of hydrate, how many grams of cuso4 are in it? how many moles of cuso4? (hint: molar mass of cuso4 = 159.6 g / mole. what per cent of the hydrate is cuso4? you may convert the mass of cuso4 to moles.)

Use the table to identify the phase and phase changes of the elements under the given conditions. write the name of the substance, phase, or phase change

One of the hopes for solving the world's energy problem is to make use of the fusion reaction 21h +31h --> 42he + 10n + energy how much energy is released when 1 mol of deuterium is fused with 1 mol of tritium according to the above reaction? the masses of the atoms and the neutrons are as follows: 21h = 2.0140 amu 31h = 3.01605 amu 42he = 4.002603 amu 10n = 1.008665 amu. the speed of light is 2.9979 x 108 m/s.
