1. Laughing gas (nitrous oxide, N2O) is sometimes used as an anesthetic in dentistry. It is produced when ammonium nitrate is decomposed according to the reaction
NH4NO3(s) −→ N2O(g) + 2 H2O(ℓ).
How much NH4NO3 is required to produce
29.7 g of N2O?
2. Carborundum (SiC) is a hard substance made
by combining silicon dioxide with carbon (C)
as follows:
SiO2(s) + 3 C(s) −→ SiC(s) + 2 CO(g).
What mass of SiC is formed from the complete reaction of 1.43 mol of carbon?
Answer in units of g

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.

they are both synthetic elements
