Mr. Sang grew a seed inside a clear, plastic bag. He taped the bag to a piece of cardboard. After the roots had grown about 2 inches, he turned the cardboard 90 degrees. Now, the stem and roots of the plant were sideways. He left the plant to grow for 2 more weeks.
When he took the plant out, it looked like this. What made the plant grow this way?
A)
Being turned made the roots keep growing sideways.
B)
Gravity made the roots grow down when the plant was turned.
Being grown in a plastic bag made the roots grow the wrong way.
D)
Light made the roots change direction when the plant was turned.

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.
