the moles of hydronium ion equals the moles of hydroxide ion.

the burette has been emptied.

3.)
adding more acid or more base will no longer change the ph of the solution.
which of the following would make the best buffer solution?

hcl and hno2

naoh and oh-

hcl and naoh

hno2 and no2-

4.)
to balance the following half-reaction, al → al3+, how many electrons need to be added?

3 to the reactant side

3 to the product side

1 to the reactant side

1 to the product side

i can ! i just need to know what the paragraph is! : p

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.
