Both ethylene (c2h4) and benzene (c6h6) contain the cc bond. the reactivity of ethylene is greater than that of benzene. for example, ethylene readily reacts with molecular bromine, whereas benzene is normally quite inert toward molecular bromine and many other compounds. explain this difference in reactivity.

answer:

n = 3  

step-by-step explanation:

a d subshell has a secondary quantum number, l = 2.

the allowed values for l are 0, 1,   2, 3, … n – 1.

we can write this mathematically as

    l ≤ n – 1     add 1 to each side

l +1 ≤ n     reverse the inequality

  n ≥ l + 1

thus, if l = 2, n ≥ 3

thus, the lowest energy level where you can find a d subshell is n = 3.

answer: 93.9 kpa

explanation: according to dalton's law, the total pressure of a mixture of gases is the sum of individual pressures exerted by the constituent gases.
