How do molecules differ from one another?

Answer 1

Well don't they have different elements?

And so, their reactivity, polarity, structure, melting point, boiling point, density, and many more properties change. Does mercury amalgam alloy #(Hg*Al)# look like water #(H_2O)#? Clearly not, as water looks clear, while amalgam is a silver and shiny alloy.

Also, we see that some molecules are more reactive than others. Acids and bases tend to be more reactive than neutral oxides. When we put metals in acids, we see bubbling and the metal gets used up, but if we put them in neutral oxides such as carbon monoxide #(CO)# and nitric oxide #(NO)#, nothing will happen.

Some molecules are polar, such as hydrogen fluoride #(HF)#, while some are non-polar, such as methane #(CH_4)#.

I just gave some examples, and there are many more.

The type, number, and bonding patterns of atoms determine molecular properties. Chemical composition and atom arrangement distinguish molecules.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
