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:

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.

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation
