Briefly explain the three lines of evidence for the earth's relative age.

1.- Oldest rock in the Earth

2.- Rocks of the moon

3.- Rocks of the meteorites

Explanation:

1.- In our Earth, there has been different studies that show the age of different layers in our planet by radiation, in this way, we can imagine how has been changing the surface trough this millions of years.

2.- By sonic sounds, the rocks of the moon can be analyze to calculate it relative age, and how this is corresponding to the age of our planet.

3.- Finally, another evidence of our Earth age, is by comparing the mass of different space bodies with our planet.

Hope this info is useful.

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.
