As two atoms of fluorine combine to become a molecule of fluorine, a bond is formed as energy is released. A molecule is more stable at a lower eneergy level.

When two atoms of Florine combines, they share an electron pair to complete it's octet. This result is formation of single bond between two fluorine atoms. This process is exothermic in nature, and hence, heat is liberated during the process of bond formation.

How many moles of Cu do you need to react with 12 moles of O2? 2Cu(s) + O2(g) 2CuO(s)

zzz [600]

Answer:

24 mol Cu

General Formulas and Concepts:

Chemistry

Stoichiometry

Explanation:

Step 1: Define

RxN: 2Cu (s) + O₂ (g) → 2CuO (s)

Given: 12 moles O₂

Step 2: Stoichiometry

$12 \ mol \ O_2(\frac{2 \ mol \ Cu}{1 \ mol \ O_2} )$ = 24 mol Cu

Step 3: Check

We are given 2 sig figs.

Our final answer is in 2 sig figs, so no need to round.

Give the charge and full ground-state electron configuration of the monatomic ion most likely to be formed by the element. rb

devlian [24]

Actually Rb or Rubidium in zero state has the following electron configuration:

1s22s22p63s23p63d104s24p65s1

However we can see that the ion has a 1 positive charge, which means that it lacks 1 electron, therefore the answer from the choices is:

d. rb+: 1s22s22p63s23p64s23d104p6
