3. Next in test tube 1, you stressed the system by adding Ca(NO3)2. a. Did the addition of Ca(NO3)2 stress the system? Were you adding reactant or product to the
system by adding Ca(NO3)2?
b. Did the system respond to this stress by shifting to make more product or by shifting to make
more reactant?
c. What was the evidence of this response?
d. What else did you observe in the test tube?

radioactive decay occurs in unstable atomic nuclei – that is, ones that don't have enough binding energy to hold

the nucleus together due to an excess of either protons or neutrons.

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.
