Elaborate what knowing that carbon-14 has an atomic number of 6 tells us about the atom. a) carbon-14 contains 6 baryons, 7 prions, and 8 neutrons. b) carbon-14 contains 7 electrons, 7 protons, and 7 quarks. c) carbon-14 contains 6 electrons, 6 protons, and 8 neutrons. d) carbon-14 contains 8 electrons, 6 photons, and 6 neutrons.

The correct answer is C, This information tells us that carbon-14 is an isotope of carbon-12. Isotopes are atoms with the same atomic number but different mass number. Atomic number is the number of protons in the nucleus of an atom. Mass number is the total number of protons and neutrons in an atomic nucleus. Both carbon-14 and carbon-12 have 6 protons, 6 electrons, but they differ in the fact that carbon-14 has 8 neutrons as opposed to 6 neutrons in carbon-12.

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.
