for 3.64 g of the combination of RO, R(OH) 2 RCO3 acts just enough with 117.6g of 10% h2so4 solution after the reaction yields 0.448 l of gas in the center and a single salt solution with a concentration of 10 , 87% (d = 1.093) molar concentration is 0.545 M a. determine the metal R b. calculate mass percent of each substance in X

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.
