Answer: Alcohol isomers :
(1) CH3CH2CH2CH2CH2OH = n-pentanol (pentane-1-ol)
(2) CH3CH2CH2CH(OH)CH3 = 2-pentanol (pentane-2-ol)
(3) CH3CH2CH(OH)CH2CH3 = 3-pentanol (pentane-3-ol)
(4) CH3CH2CH(CH3)CH2OH = 2-methyl-1-butanol
(5) CH3CH2C(CH3)(OH)CH3 = 2-methyl-2-butanol
(6) CH3CH(OH)CH(CH3)CH3 = 3-methyl-2-butanol
(7) CH2(OH)CH2CH(CH3)CH3 = 4-methyl-1-butanol
(8) CH3CH(CH3)CH2CH2OH = 3-methyl-1-butanol
(9) CH3C(CH3)2CH2OH = 2,2-dimethyl-1-propanol

Ether isomers:
(1) CH3CH2CH2CH2-O-CH3 = methyl butyl ether
(2) CH3CH2CH2-O-CH2CH3 = ethyl propyl ether
(3) CH3CH(CH3)CH2-O-CH3 = methyl isobutyl ether
(4) CH3CH2CH(CH3)-O-CH3 = methyl sec-butyl ether
(5) CH3CH2-O-CH(CH3)CH3 = methyl isopropyl ether

What is Avogadro's number?

The Avogadro number is the proportionality factor which is the number of particles such as atoms, molecules, or ions in one mole of a substance.

Avogadro's number possesses a numeric value of 6.022 × 10²³ reciprocal moles. Avogadro's constant is named by Stanislao Cannizzaro after the scientist Amedeo Avogadro.

Given, the mass of the carbon in sample = 6 g

The number of atoms of one mole of carbon = 6.022 × 10²³

The atomic mass of one mole of carbon = 12 g

It means 12 g of the carbon has atoms = 6.022 × 10²³ carbon atoms

Then 6 grams of carbon will have atoms = (6/12) × 6.022 × 10²³

= 3.011 × 10²³ carbon atoms

Therefore, the atoms of carbon in 6 g of sample of carbon are 3.011 × 10²³ atoms.

Evaporation, change from liquid to gas occurs at 100°C.

What is the difference between an electrons orbital and a planets orbital?

Answers

The words may sound similar "orbit" and "orbital", but both are actually quite different. In our solar system, the paths on which the planets revolve around are called orbits. When talking about orbitals, it is an uncertain area inside an atom within which the probability to find an electron(s) is highest.
I hope this helps.

3. 56 g of N₂ reacts 9 g of H₂ in a closed vessel to form NH3. Which reactant is left in excess and how 2207 much? 1) N₂, 10. g +3th = 2013/ (3) N₂, 14 g (2) H₂, 4 g (4) H₂,3 g N₂- to d A

Answers

Answer: the reactant left in excess is H₂, and the amount of excess H₂ is 4.5 moles - 3 moles = 1.5 moles.

Explanation: Moles of N₂ = mass of N₂ / molar mass of N₂

Moles of N₂ = 56 g / 28 g/mol = 2 moles

Moles of H₂ = mass of H₂ / molar mass of H₂

Moles of H₂ = 9 g / 2 g/mol = 4.5 moles

How is the charge of an atom determined?
how is the amount of neutrons determined?

Answers

Atoms have positively charged protons and negatively charged electrons, the number of each tells you the charge.
The ionic charge is the number of protons subtracted by the number of electrons. They usually have the same charge, but with opposite signs, Electrons ( -) and protons ( +)
To find the neutron number,subtract the proton number from the atomic mass. It will give you the neutron number.
Hope this helps.
