vIt is the middle of winter when you go to the store to buy some balloons for a birthday party. After you get to your car with the balloons, you remember you forgot to get a birthday card so you leave the balloons in the car and go back into the store. When you get back to your car the balloons you just bought are now almost flat. Which statement BEST explains what happened?

Explanation:

sorry i do know

The balloons were filled in a warm room with warm air at a certain volume. When they are brought into the car, which was at a much lower temperature, the air inside the balloons cooled down so much that the volume shrunk in the process. This is in accordance to Charles's law where a decrease in the temperature of the gas causes a reduction in its volume.

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.
