Name the reaction processes that lead to the two types of synthetic polymers.

Ksivusya [100]

The reaction processes that lead to the two types of synthetic polymers are chain reaction polymerization and step reaction Polymerization.

<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. This polymerization method is used to produce polymers having lower molecular weight as compared to chain reactions and requires higher temperatures to occur.

Unlike chain reaction polymerization, this reactions include two different types of di-functional end groups or monomers which react with one another, forming a chain.

Step wise polymerization produces a small molecular by-product (water, HCl, etc.). The example is the formation of Nylon 66.

Thus, we concluded that the reaction processes that lead to the two types of synthetic polymers are chain reaction polymerization and step reaction Polymerization.

A mixture of 0.600 mol of bromine and 1.600 mol of iodine is placed into a rigid 1.000-L container at 350°C.

nata0808 [166]

The equilibrium constant for this reaction at 350°C is determined as 5.85.

<h3>Concentration of each component</h3>

concentration of bromine, C(Br) = 0.6 mol/1 = 0.6

concentration of iodine, C(I) = 1.6 mol/1 = 1.6

<h3>Create an ICE table</h3><h3>What is ICE table?</h3>

An ICE table is a tabular system of keeping track of changing concentrations in an equilibrium reaction.

ICE is an abbreviation that stands for initial, change, equilibrium.

Create ICE table for the reactants and products formed;

Br2(g) + I2(g) ↔ 2IBr(g)

I 0.6 1.6 0

C -1.19 -1.19 1.19

E 0.6 - 1.19 1.6 - 1.19 1.19

E = -0.59 0.41 1.19

<h3>Equilibrium constant </h3>

The equilibrium constant is calculated as follows;

KC = [IBr]²/[Br][I]

KC = (1.19²) / (0.59 x 0.41)

KC = 5.85

Thus, the equilibrium constant for this reaction at 350°C is determined as 5.85.

A scientist has isolated a fatty acid that has 26 carbons. most of the carbon atoms in the fatty acid chain are connected by sin

Shtirlitz [24]

Answer:
<span>Based on giveninformation, the compound is a <u>Poly Unsaturated</u> fatty acid.

Explanation:
Fatty acids are carboxylic acids with -COOH functional group and a chain of hydrocarbons.

Fatty Acids are classified as,

i) Saturated Fatty Acids:
Those Fatty Acids in which there is no double bond between the carbon chain are called as saturated fatty acids.

Examples:
Lauric Acid </span>CH₃(CH₂)₁₀COOH<span>

Myristic Acid </span>CH₃(CH₂)₁₂COOH<span>

Palmitic Acid </span>CH₃(CH₂)₁₄COOH

ii) Unsaturated Fatty Acids:
Those Fatty Acids in which contain a single double bond (mono-unsaturated) or more than one double bond (poly-unsaturated) d between the carbon atoms in a chain are called as unsaturated fatty acids.

Examples:
<span>Linoleic acid
</span>
<span>Vaccenic acid

</span><span>Palmitoleic acid

The saturated fatty acid containing 26 carbon atoms is called as Cerotic acid. While cerotic acid containing a double bond at position 3 and 9 has a IUPAC name H</span>exacosa-3,9-dienoic acid with following structure.

Put these steps of solar

kupik [55]

Answer:

3-1-5-2-4

Explanation:

scientists believe that the solar system was formed when some star had its explosion and due to its explosion there were waves generated in the space thus squeezing clouds and dust eventually gravity pulling everything together forming solar nebula. the clouds spin faster and faster thus making it into a thin disk and also the cloud becoming hotter and dense thus forming stars.
