The chemical formulas of calcium and magnesium chloride are CaCl_2 and MgCl_2

Explanation:

A chemical formula is the representation of a substance in terms of chemical symbols showing the elements present in a compound and their relative proportion.

Calcium is having an atomic number of 20 has electronic configuration of 1s^22s^22p^63s^23p^64s^2 . It can lose two electrons to have an oxidation state of +2.

Magnesium is having an atomic number of 12 has electronic configuration of 1s^22s^22p^63s^2 . It can lose two electrons to have an oxidation state of +2.

Chlorine is having an atomic number of 17 has electronic configuration of 1s^22s^22p^63s^23p^5 . It can gain one electron to have an oxidation state of -1.

Thus the chemical formulas of calcium and magnesium chloride are CaCl_2 and MgCl_2

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

$\theta=\dfrac{\pi}{3},~2\dfrac{\pi}{3},~3\dfrac{\pi}{3},~4\dfrac{\pi}{3},~5\dfrac{\pi}{3}.\\\\\\\rightarrow \theta=60^\circ,12^\circ,180^\circ,240^\circ,300^\circ.$

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.

Answer from: Quest

the balanced equation for reaction of ca metal with o2 to produce cao is as below

2 ca+ o2→ 2 cao2

explanation

the reaction is balanced since the number of atoms in reactant side is equal to number of atoms in product side. for example they are 2 atom of ca in reactant side and 2 atoms of ca in the product side.

the process is a meet the requirement of redox reaction because : calcium is oxidized from oxidation state 0 to 2+ while oxygen is reduced from oxidation state 0 to 2-
