How would you predict the properties of sodium chloride compare with those of its constituet elements?

Sodium is a metal. Chlorine is a non-metal.

Sodium chloride should be an ionic compound.

IThe physical properties of sodium chloride should be

•solid

•high melting and boiling points

•brittle

•poor conductor of electricity

•aqueous solutions should be good conductors of electricity

The physical properties of sodium are

•solid

•metallic lustre

•malleable and ductile

•good conductor of electricity

The physical properties of chlorine are

•pale green gas

•low melting and boiling points

•poor conductor of electricity

1.consider the following balanced equation and answer parts a through. show calculations for each part.  

3 ag(s) + 4 hno3(aq) → 3 agno3(aq) + no(g) + 2 h2o(l)  

a. calculate the number of moles of agno3 produced by the reaction of 3 moles of ag with excess hno3. if the number to the left of the compound represents the number of moles of the compound which are present, then 3 moles of ag react with 4 moles hno3 to produce 3 moles agno3 (aq).

so the answer to a would be 3 moles.

b. calculate the number of moles of agno3 produced by the reaction of 108 grams of ag with excess hno3.  

i'm not sure how to plug in the grams of silver into an equation using moles to find how many moles are produced.

c. calculate the number of grams of agno3 produced by the reaction of 108 grams of ag with excess hno3  

d. calculate the number of moles of no produced as a byproduct of the reaction of 108 grams of ag with excess hno3.  

e. calculate the number of grams of no produced as a byproduct starting with 108 grams of ag and excess hno3.  

explanation:

i believe the answer is a.
