Anovel process for obtaining magnesium from sea water involves several reactions. write a balanced chemical equation for each step of the process.
(a) the first step is the decomposition of solid calcium carbonate from seashells to form solid calcium oxide and gaseous carbon dioxide
(b)the second step is the formation of solid calcium hydroxide as the only product from the reaction of the solid calcium oxide with liquid water
(c)solid calcium hydroxide is then added to the seawater, reacting with dissolved magnesium chloride to yield solid magnesium hydroxide and aqueous calcium chloride
(d)thw solid hydroxide is added to a hydrochloric acid solution producing dissolved magnesium chloride and liquid water
(e) finally, the magnesium chloride is melted and electrolyzed metal and diatomic chlorine gas.

a)

b)

c)

d)

e)

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

he salts which are soluble in water are designated by symbol (aq), those in solid form are represented by (s), those in liquid form are represented by (l) and those in gaseous form are represented by (g) after their chemical formulas.

a) decomposition of solid calcium carbonate from seashells to form solid calcium oxide and gaseous carbon dioxide:

b) formation of solid calcium hydroxide as the only product from the reaction of the solid calcium oxide with liquid water

c) calcium hydroxide is then added to the seawater, reacting with dissolved magnesium chloride to yield solid magnesium hydroxide and aqueous calcium chloride

d) solid hydroxide is added to a hydrochloric acid solution producing dissolved magnesium chloride and liquid water

e) magnesium chloride is melted and electrolyzed metal and diatomic chlorine gas.

dynamic equilibrium is the answer.

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.
