Answer: 0.113 moles of NaCl are created as a result of decomposing 12 grams of
.
Explanation:
To calculate the moles :

The balanced chemical equation for decomposition of
is:
According to stoichiometry :
2 moles of
give = 2 moles of 
Thus 0.113 moles of
give =
of 
Thus 0.113 moles of NaCl are created as a result of decomposing 12 grams of
.
Answer:
addition polymerization
Explanation:
In addition polymerization, the monomers are simply joined to each other to form a polymer having the same empirical formula as the monomer but of higher relative molecular mass. The monomers in addition polymerization are usually simple unsaturated molecules such as alkenes.
We can deduce the reaction to be an addition polymerization because of the the attachment of n to both the unsaturated monomer and the saturated polymer without the loss of any small molecule. If it was a condensation polymerization, there would have been an accompanying loss of a small molecule such as water.

An earthquake happens when tectonic plates move against each other. A oceanic and a continental tectonic plates might move against each other. When that happens water is pushed upwards and it creates ripples that then move towards land. It's like throwing a rock in water but a lot bigger.
