N76 [4]
Those reactions in which Alkyl Halide reacts with the solvent without the involvement of any acid or base is called as Solvolysis. In given problem <em>tert</em>-Butyl Bromide is a tertiary Alkyl Halide and we know well that tertiary alkyl halides undergo SN¹ and E¹ elimination reaction due to the formation of stable tertiary carbocation. In given example after the formation of carbocation when Isopropyl act as nucleophile it will produce ether and when it acts as a base it will produce unsaturated compound. The reaction along with both products is shown below,

How do movements and interactions of air masses cause change in the weather?
ollegr [7]
The way the air moves affects the weather, because winds move heat and cold temperatures as well as moisture from one place to another, transporting conditions from one geographical zone to another. The way winds pass each other, and the direction they move, also affects what weather a region will see on any given day.

Explanation:

This problem deals with balancing of chemical equations.

   Every chemical equations obey the law of conservation of matter which states that "in chemical reactions, matter is usually conserved and are not produced, they are simply recombined".

  Equation of reaction:

      BaO₂   +   H₂SO₄  ⇒  H₂O₂  +  BaSO₄

Let us use a mathematical approach to balance this equation by setting up simple algebraic equations:

        aBaO₂   +   bH₂SO₄  ⇒  cH₂O₂  +  dBaSO₄

a, b, c and d are the number of moles that will balance the equation;

 Conserving Ba:   a = d

                       O:   2a + 4b = 2c + 4d

                        H:    2b = 2c

                         S:    b  = d

now let a = 1

              d = 1

               b = 1

                c  = 1

we see that the equation is already balanced
