When a student removed the crucible cover after the first strong heating, some of the white solid was knocked from the cover to the floor and lost. 1. What effect would this have on the calculated number of moles of magnesium in the compound? Explain 2. What effect would this have on the calculated number of moles of oxygen in the compound? Explain

answer: the figure is attached herewith.

step-by-step explanation:   we are given to sketch a unit circle and label the terminal points corresponding to

in the attached figure, we have drawn a unit circle, with centre at o(0,0) and radius 1 unit. we have labelled the points a, b, c, d and e corresponding to the angles below

∠aox = 60°,

∠box = 120°,

∠cox = 180°,

∠dox = 240°,

∠eox = 300°.

and the coordinates are a(0.5,1), b(-0.5,1), c(-1,0), d(-0.5,-1) and e(0.5,-1).

thus, the answer is complete.

the answer is b. dilution

hi my dude or dudette
