Naming compounds, mass percent, reaction, density

The attached is what I need step by step answers and solutions to.  

1) Name the following compounds (or write the molecular formula) and indicate whether they are ionic or covalent:

      NOTE:  Please, please go through the steps for each one on how you get the answer.  Now, I know you are supposed to first determine if ionic or covalent.  AN ionic compound is a metal + a non metal = ionic and a non metal + nonmetal = covalent compound.  As you do each one do each step on finding if ionic or covalent and why.  Then do the swapping of ions for naming I guess.  I also know that if a roman numeral appears it is a transition metal.  The di, tri and penta's, etc are only used on covalent compounds.  Please show me how to use all this info and whatever I missed to solve for a. to j. step by step so I can see and understand it as simple as possible.  Also, in "j" what is the dot for?

a. Al(POsub4)
b. Cr(ClOsub2)sub2
c. Mnsub2Osub3
d. NHsub4NOsub3
e. HF
f. Sulfur hexafluoride
g. Nickel (II) sulfide
h. Rubidium bromide
i. Chlorine gas
j. CuSOsub4 ∙ 5 Hsub2O


2) Calculate the mass percent of silver in silver Chloride.  By mass, is there more silver or chlorine in this compound?

Again, please give step by step simple answers and solution please.


3) The mass of a copper coin is 3.20g.  If it is pure copper, how many moles of copper would the coin contain?  How many atoms of copper would be present in the coin?

Again, please give step by step answers and make simple to understand.


4) Calculate the density of your book, given a volume of 162in^3 and a mass of 2.50kg.  ( 1 inch = 2.54 cm)

Again, please give step by step answers and make simple to understand.




5) Write out the following reactions in their proper form:

a. Sodium hydroxide plus hydrogen chloride in solution reacts to form water and sodium chloride.
b. In water, Ammonia (NHsub3) reacts with hydrogen sulfate to form ammonia sulfate.
c. Iron(III) oxide in water reacts with carbon monoxide to form iron metal and carbon dioxide.

Again, please give step by step answers and make simple to understand.


6) a.In the reaction of Si(s) + 2Clsub2(g) → SiClsub4 (l) 0.507 moles of SiCl4 is produced.  How many moles of molecular chlorine were used in the reaction?

b. How many molecules of Si were consumed?

c. If 75.3grams of Clsub2 were available, would they all be consumed in producing  
    0.507 moles SiClsub4?

d. George weighs his product of SiClsub4 and finds he actually formed 42.3g
    SiClsub4.  What was his percent yield?

Again, please give step by step answers and make simple to understand.
