3. Determine if the overall solution containing the following salts would be acidic, basic or neutral. Write out the ion with their conjugates and state if the conjugate would be considered strong or weak. a. FeCl2 b. KHCO3 c. NH4F

The following solutions would be produced from dissociation of these salts: A. acidic B. Basic C. Acidic

Explanation:

Salts of weak bases and strong acids neutralization would hydrolyze, which gives it a pH less than 7. Salts formed by neutralization reaction between strong bases and weak acids hydrolyze, which gives it a pH greater than 7.

A.) FeCl2 (aq) + H20 ⇄ ------- weakly acidic

B.) KHCO3(aq) + H20(aq) ⇄ ----- strongly basic

C.) NH4F + H2O ⇄   -----weakly acidic

This is due to the fact that the anion will become a spectator ion and fail to attract the H+, while the cation from the weak base will donate a proton to the water forming a hydronium ion.

C₂H₆ + 2Cl₂ => C₂H₄Cl₂ + 2HCl

Or from left to right:

1, 2, 1, 2

Explanation:

To balance an equation, start by counting the number of atoms of each element on both sides.

C₂H₆ + Cl₂ => C₂H₄Cl₂ + HCl

C  2                 C  2

H  6                 H  5

Cl  2                Cl  3

We should increase the number of hydrogen atoms (H) on the right (products).

C₂H₆ + Cl₂ => C₂H₄Cl₂ + 2HCl

C  2                 C  2

H  6                 H  6

Cl  2                Cl  4

Increase the number of chlorine atoms (Cl) on the left (reactants).

C₂H₆ + 2Cl₂ => C₂H₄Cl₂ + 2HCl

C  2                  C  2

H  6                  H  6

Cl  4                 Cl  4

The equation is now balanced because there are the same number of atoms on each side.

C₂H₆ + 2Cl₂ => C₂H₄Cl₂ + 2HCl

or, if your drop down menus need you to write "1".

1C₂H₆ + 2Cl₂ => 1C₂H₄Cl₂ + 2HCl

The correct format is not to write the "1".
