How can you tell which ionic compounds will react in an aqueous solution

Chemistry

1.  Determine if the ionic substances can break apart into ions.
 - e.g. CaCO3 isn't very soluble, do it can't dissolve and dissociate.  If it can't pop apart, no ions.
2.  Swap the partners for all the other ions that you can get from step 1.  You can skip pairings with the same charge - a + can't get close to another + to react.
3.  Use solubility, acid/base, and redox rules to see if anything will happen with the ions in solution.<span />

Two lobes.

The shape of four sp3 hybrid orbitals is part s and part p-each has two lobes but one lobe is much bigger (which is the lobe used for bonding)

1) The amount of PbS produced will be 16.27 grams

2: The amount of Fe produced will be 118.72 grams.

<h3>Stoichiometric problems</h3>

1) The equation is balanced. The mole ratio of lead (II) acetate to the PbS is 1:1.

Mole of 22.11 lead acetate = 22.11/ 325.29 = 0.06797 moles

Equivalent mole of PbS = 0.06797 moles

Mass of PbS = 0.06797 x 239.3 = 16.27 grams

2) from the equation, the mole ratio of Al to Fe is 1:1.

Mole of 57.2 g Al = 57.2/26.98 = 2.12 moles

Equivalent mole of Fe = 2.12 moles

Mass of Fe = 2.12 x 56 = 118.72 grams.
