10x-74=92
answer for algebra

Answers

Answer 1

10x - 74 = 92  --->  (Add 74 to both sides. This gets rid of the 74)

     + 74   +74

10x = 166   --->  (Simplify. The 74 you added to the 92 becomes 166)

10x/10 = 166/10    ---> (Divide both sides by 10. This gets the x by itself)

v(Simplify)v

x = 83/5    OR    x = 16.6

What quantity in moles of chlorine gas at 120.0 °C and 33.3 atm would
occupy a vessel of 36.5 L?

Answers

The number of chlorine moles present in the vessel are 37.67 mol.

What are moles?

Moles are the number of substances present in a system which consists of entities like ions, atoms, or molecules as much as atoms in the weight of pure carbon which is 12 grams. It is the SI unit of amount of substance.

One mole of a substance is equal to the Avogadro Number which is equal to 6.022×10²³.

According to Ideal gas law,

PV=nRT where,

P= Pressure

V= Volume

n= number of moles

R= Ideal gas constant

T= temperature (in Kelvin)

n= PV/RT

⇒33.3×36.5/0.0821×393

⇒1215.45/32.2653

⇒37.670

Name the following alkyl halides

Answers

The IUPAC nomenclature of compound 1 is 5-bromo-2-methylchloridepent-2-ene and the name for structure 2 is 5-iodo-hex-2-ene

IUPAC nomenclature is the method of naming the organic chemical compounds by following certain rules and criteria given by IUPAC.

This nomenclature is based on naming a molecules longest chain of carbons connected by single bonds, whether in a continuous or in ring form. Everything else like multiple bonds or atoms are other than carbon and hydrogen are indicated by prefixes or suffixes according to a specific set of priorities.

In structure 1 we can see that we are number so that the double bond that is present gets the least priority and then the naming is done in the alphabetic order. so the name is 5-bromo-2-methylchloridepent-2-ene

In structure 2 the same thing is followed and the name of the structure is

5-iodo-hex-2-ene

Explanation:

1. Outline a synthesis showing the necessary reagents and intermediate molecules for the following
transformation. For carbon sources, use alkyl halides with 4 or fewer carbons. You will need to use
more than one reaction.

Answers

A synthesis showing the necessary reagents and intermediate molecules for carbon sources, use alkyl halides with 4 or fewer carbons is zinc and copper pair in alcohol to reduced alkyl halide.

Which alkyl halide is more reactive ?

The Zn/Cu pair in alcohol is used to reduce alkyl halides. In alcohol, the Zn/Cu pair substitutes hydrogen for the halide of an alkyl halide to generate hydrocarbons. The Zn/Cu combination produces methane in alcohol by taking the iodine out of methyl halide and adding hydrogen.

Thus, a synthesis showing the necessary reagents and intermediate molecules for carbon sources, use alkyl halides with 4 or fewer carbons is zinc and copper pair in alcohol to reduced alkyl halide. Alkyl iodide is more reactive.
