Explanation:
Polymerization is the process whereby two or more monomers link together to form a compound of high molecular mass called a polymer.
There are two kinds of polymers;
-Addition polymers
-Condensation polymers
Addition polymers are formed by the joining of two or more monomers to form a polymer without the elimination of a small molecule.
Condensation polymers are formed by the joining of two or more molecules to form polymers with the elimination of a small molecule.
The main difference between polyethene and polyester is that polyethene is an addition polymer while polyester is a condensation polymer.
In polyethene, ethene molecules are joined together having the repeating unit as [-CH2-CH2-]n.
In polyester, the polymer arises from the reaction of carboxylic acid and an alcohol and loss of water molecules.
Answer:
For pure substances, the mass and volume will always be the same or will always change the same way because all substance are the same throughout.
While for mixtures, you can have varying amount of each component therefore mass and volume will not change the same way for substances
FC(C) = 4 - 0.5*8 - 0 = 0) FC(Cl) = 7 - 0.5*2 - 6 = 0
Answer:
First check to make sure you have a balanced equation
Second use mole ratios to set up what you need to know
Finally convert the moles to grams using the correct molecular weight
I will get you started
According to the reaction above, one mole of Magnesium Nitrate is produced from 2 moles of Nitric Acid
1 mole of Mg(NO3)2/2 moles of HNO3
5 grams of Nitric acid contains
5 g * 1 mole/63 g of Nitric Acid = 0.079365079 moles
