Chlorine can be prepared in the laboratory by the reaction of manganese dioxide with hydrochloric acid, HCl (aq), as described b
y the chemical equation
MnO₂ (s) + 4HCl (aq) ⟶ MnCl₂ (aq) + 2H₂O (l) + Cl₂ (g)
How much MnO₂ (s) should be added to excess HCl (aq) to obtain 115 mL Cl₂ (g) at 25 °C and 805 Torr?

Explanation:
This is a common equation of photosynthesis.
In this process, green plants manufacture their food by using carbon dioxide and water to produce glucose and oxygen gas.
To balance this equation, let us affix coefficients to the species:
aCO₂ + bH₂O → cC₆H₁₂O₆ + d0₂
Conserving:
C : a = 6c
O: 2a + b = 6c + 2d
H: 2b = 12c
let a = 1
c =
b = 1
d = 1
multiply through by 6
a = 6
b = 6
c = 1
d = 6
6CO₂ + 6H₂O → C₆H₁₂O₆ + 60₂
