Polyester and polyamide would be two synthetic polymers, created by condensation reaction.
Answer: 
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products must be same as the mass of reactants.
For the conservation of mass, the number of atoms of each element must be same in reactants and products. Thus we need to balance the reaction by writing appropriate stochiometric coefficients.
All the hydrocarbons burn in oxygen to form carbon dioxide and water.Thus the complete balanced equation is:
Answer:
when it comes to adding or subtracting numbers, his final answer should have the same number of decimal places as the least precise value.
For example if you add 2 numbers; 10.443 + 3.5 , 10.443 has 3 decimal places and 3.5 has only one decimal place.
Therefore 3.5 is the less precise value.
So when adding these 2 values the final answer should have only one decimal place.
after adding we get 13.943 but it can have upto one decimal place. then the second decimal place is less than 5 so the answer should be rounded off to 13.9.
the answer is the same number of decimal places as the least precise value
Explanation:
I think this is the answer I'm not sure
The combination of the of two or more elements is known as a compound.
A homogenous mixture has a uniform composition all throughout. They are
similar in terms of the amount of composition present in a solution. For
example, oxygen is diatomic, O2. So oxygen is a compound because it has 2
elements combined in it. It is also a homogenous mixture if there are a lot of
O2 gases present in let’s say tank. They only differ in the place where they
are present. A compound is a representation of one molecule whereas a
homogenous mixture is present in a a solution.
