Which practice does the Montreal Protocol aim to reduce?
PolarNik [594]
Ozone which is present in the stratospheric region of atmosphere is helpful for preventing harmful UV rays from reaching the surface of earth. Due to human activity, several compounds  (specifically chlorofluorocarbons) are released in atmosphere. Due to inherent chemical stability of these compounds, the remain stable in lower region of atmosphere and slowly diffuse into stratosphere. On reaching the stratosphere, these compounds reacts with ozone and thereby depletes the effective concentration of ozone present in atmosphere. Hence, <span>the Montreal Protocol was signed in 1987 by major countries of the world. This aim of this protocol was to protect the stratospheric ozone layer by phasing out the production and consumption of ozone-depleting substances.</span>

Answer:

¹⁶⁸₇₉Au

Explanation:

The symbol of the atom is given as;

          ¹⁷²₈₁Tl

If undergoes a nuclear reaction and it ejects an alpha particle;

 An alpha particle is the same as an helium atom

      ¹⁷²₈₁Tl  →  ₂⁴H   +     ₐᵇK

K is the hypothetical symbol of the new atom

b is the new mass number

a is the new atomic number;

 Conserving mass number;

        172  = 4 + b

        b  = 172  - 4  = 168

Conserving atomic number;

        81  = 2 + a

        81 - 2  = a

         a  = 79

The new compound is gold with a symbol of;

       ¹⁶⁸₇₉Au
