Well in polymerization or in dehydration synthesis, the individual monomer molecules contain either H or OH attached to the end of their respective molecules. When they chemically compline together both the H and OH come off or break from their respective molecules and form water as a product. In place, a covalent bond is produced connecting the monomers together. In break down of polymers, with Water, the water molecule essentially disconnects the large molecule at the same place where it would have formed a covalent bond, and causes one of the monomers to bond to either a H and or OH. Separating the 2 compounds.
You should first count all the valence electrons. Then draw the central atom and single bonds to the rest (then go from there)
Answer:
2.08 moles
Explanation:
number of molecules = mass / molecular mass of SO₄
number of molecules = 200 g / 96.06 g/mol
number of molecules ≈ 2.08
Answer:
As the thermal energy of matter increases, its particles usually spread out, causing the substance to expand.

<em> i have a book about this stuff</em>
Answer:
1.35 moles
Explanation:
Calculate how many
of potassium (K) are present in a sample of 8.12x10^23 atoms of K
6.02 X 10^23 atoms are 1 mole. how many 6.02 X 10^23 are in
8.12 X 10^23
divide 8.12 X 10^23 into sets of 6.02 X 10^23
(8.12 X 10^23)/(6.02 X 10^23) =1.35 moles
