I know that I've been posting homework questions up...but I'm in desperate need of help..because Chemistry is confusing to me..and this packet doesn't go along with the book we read. So please...if you're not interested in helping me with homework questions...then please help in terms of not leaving unneccessary comments. I appreciate it. Thank you!

if there are just a few that u know the answers to..it would help me a lot still...u don't have to answer it all. I thank you all for ur time..and help!!!

1. The boiling point of an amine is (lower) than the boiling point of an alcohol.

2. Amines act as (strong bases)

3. Amines are less polar than (alcohols)

4. An amide bond is also called a (peptide bond)

5. An amino group is (polar)

AGAIN...thank you for ur help!!!

Why can't characteristic properties, such as melting point and boiling point, be used to identify subsatances while they are mixed together

I am stuck on these problems and my textbook barely mentions anything about net ionic equations. Does anyone know the net ionic equation for the following:

1) Solid calcium carbonate is heated in a vacuum.
2) Equal volumes of equimolar solutions of phosphoric acid and calcium hydroxide are mixed.
3) Powdered strontium oxide is added to distilled water.
4) Chlorine gas is bubbled through a solution of potassium bromide.
5) Carbon monoxide gas is passed over hot iron(III) oxide.

Also, what is the significance of distilled water in net ionic equations? I have a couple net ionic equations regarding distilled water...And if you have any helpful websites on net equations, please give me the link. Thanks!
