okay i need the common name for the following compounds
1.sodium hydrogen carbonate
2.solid carbon dioxide
3. sucrose
4.calcium carbonate
5. magnesium hydroxide
6. Methane
7.asorbic acid
8.Acetic Acid
9.Maltose
10. sodium chloride
My guess for #'s 3 and 9 is sugar, but other than that i have no clue, if you know any of the common names please let me know by writting the number and the name! thank you so much!!

I have no idea why this is?

A molecule of formaldehyde has the same shape as a methane molecule but the boiling points are a lot different. explain the difference between the boiling points, include lewis structures.

I have no idea why they are different in boiling point. One's a gas and ones a solid, but how would i draw them to show the difference?

Find the volume (mL) and the pH of 0.135 M HCl needed to reach the equivalence point(s) in titrations of the following. (You need to find the pH at the equivalence point, not the initial pH of the solution.)

(a) 53.0 mL of 0.216 M NH3 (NH3 Kb = 1.5*10^-5)

(b) 20.0 mL of 1.28 M CH3NH2 (CH3NH2 Kb= 4.4*10^-4

I really need help with how to solve the following question:

A hydrate of zinc nitrate has the formula Zn(NO3)2 * xH2O. If the mass of 1 mol of anydrous zinc nitrate is 63.67% of the mass of 1 mol of the hydrate, what is the value of x?

Note: 3 and 2 in the formula are subscripts.

In the book the answer to the question is x= 6, but I can't seem to get this answer. I need to know how to do it.

I am not sure, but i think it has something to do with the energy and forces that must be overcome to melt these 2 types of compounds, but i am not sure. Can anyone tell me why ionic compounds tend to have a higher melting point than molecular compounds:
