Complete and balance the equations for the following acid-base neutralization reactions. If water is used as a solvent, write the reactants and products as aqueous ions. In some cases, there may be more than one correct answer, depending on the amounts of reactants used. (a) Mg ( OH ) 2 ( s ) + HCl 4 ( a q ) → (b) SO 3 ( g ) + H 2 O ( l ) → (assume an excess of water and that the product dissolves) (c) SrO ( s ) + H 2 SO 4 ( l ) →

How many signals do you expect in the H NMR spectrum for this molecule?
Write the answer below.
Also, in each of the drawing areas below is a copy of the molecule, with Hs shown. In each copy, one of the H atoms is colored red. Highlight in red all other H
atoms that would contribute to the same signal as the H already highlighted red.
Note for advanced students: In this question, any multiplet is counted as one signal.
Number of signals in the 'H NMR spectrum.
For the molecule in the top drawing area, highlight in red any other H atoms that will contribute to
the same signal as the H atom already highlighted red.
If no other H atoms will contribute, check the box at right.
No additional Hs to color in top
molecule
For the molecule in the bottom drawing area, highlight in red any other H atoms that will contribute.
to the same signal as the H atom already highlighted red.
If no other H atoms will contribute, check the box at right.
No additional Hs to color in bottom
molecule
Check…
Incorrect
Row 2: Your answer is incorrect.
Consider this molecule:
How many H atoms are in this molecule?
22
How many different signals could be found in its 'H NMR spectrum?
12
Note: A multiplet is considered one signal.
