Answer:
It kinda is
Explanation:
The school system isn't very affective on the young adolcent minds, the crime rate is very high (indicating poverty rates) some drug smmuglers are based in Haiti, and half the city is destroyed from either people or the environment.
Answer:
tertiary
Explanation:
tertiary halogenoalkanes are more reactive than primary and secondary as the carbocation is more stable due to alkyl groups( have high electron density) donating electrons to stabilise the carbocation

First calculate the initial moles of HCl.
HCl moles i = (1.45 moles / L) * 0.5 L = 0.725 moles HCl
Then calculate how much HCl is consumed by stoichiometry:
HCl moles consumed = (12.7 g Zn / 65.38 g / mol) * (2
moles HCl / 1 mole Zn) = 0.388 moles
So HCl moles left is:
HCl moles f = 0.725 – 0.388 = 0.3365 moles
For every 1 mole HCl there is 1 mole H, therefore:
H moles final = 0.3365 moles
So final concentration of H ions is:
<span>Concentration H = 0.3365 moles / 0.5 L = 0.673 M</span>
Addition Polymerization reaction also known as chain Polymerization reaction. Monomers must contain double bond as a functional group.
<h3>What is Polymerization Reaction? </h3>
The chemical reaction which involves the addition of monomers to form higher molecular mass molecules is known as polymerization. There are two basically two types of polymerization, one is chain-reaction (or addition) and the other is step-reaction (or condensation) polymerization.
<h3>Chain-reaction (addition) polymerization</h3>
One of the most common and important types of polymer reactions is chain-reaction (addition) polymerization. This type of polymerization involves three step process including two chemical entities. The first which is known simply as a monomer. It is initially exists as simple units. Normally in all cases, the monomers must have at least one carbon-carbon double bond. Ethylene is one of the best known example of a monomer which is used to make a common polymer.
<h3>
Step-reaction (condensation) polymerization </h3>
It is second type of polymerization reaction. This polymerization method is used to produce polymers having lower molecular weight as compared to chain reactions and requires higher temperatures to occur.
In this type of reaction, monomers must have two functional group.
Thus, we concluded that the Monomers must contain double bond as a functional group in addition Polymerization reaction.
