5. If KHP sample #1 requires 19.90 mL of NaOH solution to reach an endpoint, what volume should be required for samples #2 and #3? NaOH volume is required to reach and endpoint roughly 30.15mL per trial due to the amount of acetic acid being the same in each 10.0-mL vinegar samples.

6. If vinegar sample #1 requires 29.05 mL of NaOH solution to reach an endpoint, what volume should be required for samples #2 and #3?

7. A 0.875-g sample of KHP (204.23 g/mol) is dissolved in water and titrated with 20.75 mL of NaOH solution to a permanent endpoint. Refer to Example Exercise 20.1 and calculate the molarity of the NaOH solution.

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:

b) nuclear ive learned that in a pedtrodic table

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.
