The major organic product of the reaction shown below. он +HBr You do not have to consider stereochemistry. The product is Ether i.e. CH3−CH2−O−CH2−CH3.
Stereochemistry is a branch of chemistry that studies and manipulates the relative spatial arrangement of atoms within molecules. The study of interactions between stereoisomers, which have various structural formulas but the same chemical formula and arrangement of linked atoms (constitution) by definition, is known as stereochemistry (the three-dimensional orientations of their atoms in space). Due to the fact that the prefix "stereo-" signifies three-dimensionality, it is also known as 3D chemistry. Stereochemistry encompasses all of chemistry, including organic, inorganic, biological, physical, and especially supramolecular chemistry. Stereochemistry include techniques for identifying and defining these relationships, the effects these relationships have on the chemical or biological characteristics of the molecules in question, and how these relationships affect the reactivity of the molecules in question (dynamic stereochemistry). One important field of stereochemistry is the study of chiral compounds, or molecules lacking a plane of symmetry and not superposable on their mirror copies. The word "chiral," which is derived from the Greek word "cheir," which also denotes handedness, describes objects that have a "left-handed" and "right-handed" shape.

How many particles are in a 34 g sample of Al2(SO4)3?
please help!
Answer:
5.98 × 10^22 particles
Explanation:
To get the number of particles (nA) in a substance, we multiply the number of moles of the substance by Avogadro's number (6.02 × 10^23)
The mass of Al2(SO4)3 given in this question is as follows: 34grams.
To convert this mass value to moles, we use;
Mole = mass/molar mass
Molar Mass of Al2(SO4)3 = 27(2) + {(32 + 16(4) }3
= 54 + (32 + 64)3
= 54 + 288
= 342g/mol
mole (n) = 34/342
n = 0.0994mol
number of particles (nA) of Al2(SO4)3 = 0.0994 × 6.02 × 10^23
= 0.598 × 10^23
= 5.98 × 10^22 particles

When performing a neutralization reaction, how should students test the solution to be sure which is the acid and which is the base?
Explanation:
La reacción entre un ácido y una base se llama neutralización. Cuando en la reacción participan un ácido fuerte y una base fuerte se obtiene una sal y agua. Si una de las especies es de naturaleza débil y la neutralización se produce en disolución acuosa también se obtiene su respectiva especie conjugada y agua.

Explanation:
As altitude increases, what happens to air pressure the choices are it fluctuates, it increases, it decreases or it stays the same
Answer:
it decreases
Explanation:
It is a common saying the pressure decreases with height. This means that as altitude increases, the pressure of air decreases. The higher you go above sea level, the pressure becomes lesser.
This is as a result of decrease in the amount of air above sea level and hence a decrease in the density of air as altitude increases.
Hence, with increasing altitude, pressure decreases.
Answer:
It decreases

Which of the following phases of matter has a fixed volume but not a fixed shape?
A Liquid B Gas C Solid D Plasma
Answer:
C. solidExplanation:
Solid is a hard and not able to flow; not like a liquid or gas. Having no holes; not hollow. Something that is not liquid and gas. Solid has fixed volume but not a fixed shape.
The liquid is something that flows freely; a substance that is not solid or gas.
Gas is a substance that neither liquid nor solid, e.g. air.
Plasma is an electrically neutral ionized gas in an electric discharge; distinctly different from solids and liquids and normal gases.
Therefore, the correct answer is C. solid.

How is the chemical bonding between atoms of magnesium different from the chemical bonding within a crystal of aluminum iodide?
Answer:
See explanation
Explanation:
The bond between magnesium atoms is a metallic bond while the bond within a crystal of aluminum iodide is an ionic bond.
A metallic crystal consists of a sea of electrons that are electrostatically attracted to positive metal ions. This is the nature of the bonding between magnesium atoms in a crystal of magnesium.
In aluminum iodide, there is a transfer of electrons from aluminium to iodine which is typical of an ionic bond. Electrostatic interaction holds oppositely charged ions together in the crystal of aluminum iodide.

6) A student measures out 96.21 g of sulfur for an experiment. How many moles of Sulfur are in this
sample? (show your work!)
Atomic mass of Sulfur = 32g
32g of Sulfur is one mole.
1g of Sulfur is [tex] \frac{1}{32} moles [/tex]
96.21g of Sulfur is [tex] \frac{96.21}{32} moles=> 3moles(appx) [/tex]
Answer:
[tex]\boxed {\boxed {\sf 3 \ moles \ sulfur}}[/tex]
Explanation:
To convert from grams to moles, the molar mass is used. This value is the number of grams in 1 mole of a substance and it can be found on the Periodic Table. Look for Sulfur or S.
Sulfur: 32.07 g/molWe use this as a ratio.
[tex]\frac {32.07 \ g \ S}{1 \ mo;\l\ S }[/tex]
Multiply by the given number of grams.
[tex]96.21 \ g \ S*\frac {32.07 \ g \ S}{1 \ mo\l\ S }[/tex]
Flip the fraction so the grams of sulfur cancel out.
[tex]96.21 \ g \ S*\frac {1 \ mol \ S}{32.07 \ g \ S }[/tex]
[tex]96.21*\frac {1 \ mol \ S}{32.07 }[/tex]
[tex]\frac {96.21 \ mol \ S}{32.07 }= 3 \ mol \ S[/tex]
96.21 grams of sulfur is equal to 3 moles of sulfur.

What answer is it?
An atom of a certain element has 19 protons, 19 electrons, and a mass number of 39. This element is very reactive. How many neutrons are in this atom?
Answer:
There would be [tex]20[/tex] neutrons in that atom.
Explanation:
The mass number of an atom is the sum of:
the number of neutrons in this atom, andthe number of protons in this atom.Electrons do not contribute to the mass number of an atom.
From the question:
Mass number of this atom: [tex]39[/tex].Number of protons in this atom: [tex]19[/tex].[tex](\text{Mass Number}) = (\text{Number of protons}) + (\text{Number of neutrons})[/tex].
In this atom:
[tex]39 = 19 + (\text{Number of neutrons})[/tex].
Hence, the number of neutrons would be [tex]39 - 19 = 20[/tex].
