Overview
I'm working on a chemistry multi-part question and need the explanation and answer to help me learn.
1. Determine whether the chemical bonds in these compounds are strong ionic, polar covalent, slightly polar covalent, or non-polar covalent.
Describe your calculations to identify these bonds and justify their use.
a) calcium chloride
b) carbon dioxide
e) nitrogen
d) silicon tetrachloride
2. Calculate ?EN (change in electronegativity) for each of these bonds and predict the nature of the bond.
a) sodium and nitrogen
b) sulfur and oxygen
e) fluorine and fluorine
3. Both table salt and sugar dissolve in water.
However, one is a molecular compound and the other is an ionic compound.
Describe two steps to take to distinguish between two unidentified samples of these substances.
Describe the expected results.
