1. Investigating "Beta Decay" a. Start on the Single Atom tab - observe the decay of Hydrogen-3 and Carbon- 14. Use
Reset Nucleus to watch the process repeatedly. Write a description of what happens in
the beta decay of an atom. (3 pts)
b. Check your ideas with the "Custom" atom and reflect on your ideas.
New Ideas here: (3 pts)
c. Verify your ideas by using online resources to determine what the differences are
between Hydrogen-3 and Helium-3 as well as Carbon-14 and Nitrogen-14. Also, use
other resources to see what "Beta Decay" means and cite at least one valid source.

d. Practice using your ideas by predicting what would happen if the following undergo beta
decay: (2 pts each)
i, Carbon -10 →
ii. Cesium-137 -
iilThorium-234-
e Practice using your ideas by predicting what would happen Uranium-238 undergoes
alpha decay and then beta decay. (2 pts)
Uranium-238

  1.the balanced   chemical equation is as below

cu +   2 ag(no)₃ → cu(no₃)₂   +2 ag

2.the   much silver   produced   is   50.9 g

step 1: find the   moles of cu

moles =   mass÷   molar mass

  from periodic table the molar mass of cu = 63.5 g/mol

moles is therefore = 15.00 g÷ 63.5 g/mol = 0.236   moles

step 2: use the mole ratio to determine the   moles of ag

from equation above   cu: ag   is 1: 2

therefore the moles of ag   =0.236   moles   x 2/1 =0.472   moles

step 3: find the mass   of ag

mass = moles x molar mass

from periodic table   the molar mass of ag =107.87 g/mol

mass   = 0.472   moles x 107.87 g/mol = 50.9 g

3.   the   much   silver   collected worth is   1.797 oz

  convert   50.9 g   to oz

that is   1 gram = 0.0353 oz

          50.9 grams =?   oz

by cross multiplication

={(50.9 grams x 0.0353 oz) / 1   gram}   =1.797 oz

v 154.9= 0.9 length length s little over 154.9cm

object 2 because all the other ones are wrong
