Which of the following is the correct molecular equation for the following reaction?

ca(clo4)2 (aq) + (nh4)2so4 (aq) →

group of answer choices

ca(clo4)2 (aq) + (nh4)2so4 (aq) → caso4 (s) + 2 nh4clo4 (aq)

ca2+(aq) + 2 clo4-(aq) + 2 nh4+(aq) + so42-(aq) → ca2+(aq) + 2 nh4+(aq) + (clo4)2so4 (s)

ca(clo4)2 (aq) + (nh4)2so4 (aq) → caso4 (aq) + 2 nh4clo4 (s)

ca(clo4)2 (aq) + (nh4)2so4 (aq) → caso4 (aq) + 2 nh4clo4 (aq)

ca2+(aq) + so42-(aq) → caso4 (s)

Ca(ClO₄)₂ (aq) + (NH₄)₂SO₄ (aq) → CaSO₄ (s) + 2 NH₄ClO₄ (aq)

Explanation:

It is a double displacement reaction or also an acid base type reaction. When we add Calcium perchlorate (Ca(ClO₄)₂) it dissociates into Perchloric acid and calcium ions. Similarly when we add Ammonium sulfate {(NH₄)₂SO₄} in water it also dissociates into ammonium ion and sulfate ions.

Then the calcium ions and and sulfate ions reacts to form Calcium sulfate which is poorly soluble in water so it precipitates out as solid.

Similarly ammonium ions gets combine with perchlorate ions to make Ammonium perchlorate which is soluble in water, so it remain as aq form.

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.
