Explanation:
While CO2 can be distilled from the air, that method is expensive and inefficient. Therefore, it is usually captured from other sources where it is a waste material. This could be anything from brewing beer to burning fossil fuels. However, the most efficient way of producing carbon dioxide is from ammonia.
Part b (r)–3-chloro-2-methylhexane will undergo a nucleophilic substitution reaction in the presence of sodium ethoxide and ethanol. complete the mechanism for the sn2 reaction and draw the products of the reaction. draw all missing reactants and/or products in the appropriate boxes by placing atoms on the grid and connecting them with bonds and including charges where needed. indicate the mechanism by drawing the electron-flow arrows on the molecules. arrows should start on an atom or a bond and should end on an atom, bond, or where a new bond should be created.
Answer:
See answer below
Explanation:
To understand this, we need to make the reaction involved with the given configuration. Configuration R means that the substituents of the molecule, the priority order goes clockwise (From heaviest to lightest) so, if an Sn2 is ocurring in the reaction this means that the nucleophile, which in this case, is the sodium ethoxide will attack the molecule in the opposite side of the leaving group (which is the chlorine).
Also when this occurs, as Sn2 is a bimolecular reaction and is held in one step, it occurs an inversion in the configuration of the product. So, it's the innitial reactant was R, then the final product will be S.
The mechanism and product can be watched in the attached picture

In order to prove that the Law of Conservation Mass is obeyed, what are the coefficients
needed to balance the following reaction:
C3Hg +
02
1
CO2 +
H2O
Answer: [tex]C_3H_8+5O_2\rightarrow 3CO_2+4H_2O[/tex]
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
The balanced chemical equation for combustion of propane will be :
[tex]C_3H_8+5O_2\rightarrow 3CO_2+4H_2O[/tex]

How many grams are in 8.5 moles of lithium oxide?
From the following elements: lithium, beryllium, and fluorine, predict which
one will have the largest second ionisation energy. Explain your answer.
Answer:
The element that has the largest second ionization energy is;
Lithium, Li
Explanation:
The given elements and their positions on the periodic table are;
1) Lithium is located in group 1, period 2 position on the periodic table
2) Beryllium is located in group 2, period 2 position on the periodic table
3) Fluorine is located in group 17, and period 2 position on the periodic table
The first ionization energy of the atoms in the periodic table increases across the periods from left to right and also increases from bottom to the top within a group
However for the second ionization energy, which is the energy required to remove an electron from an atom that has one less electron, we have;
The electron configuration of the given of ions that take part in the reaction for the removal of the second ionization energy are;
Li⁺ = [He} 2s⁺
Therefore, the second ionization energy is the removal of an electron from the stable duplet of the helium atom (the core of the lithium atom) which require about 7297 kJ/mol
For beryllium, we have;
Be⁺ = [He]2S¹⁺
Therefore, the second ionization requires the removal of the remaining one electron in the valence shell, which will then lead to the remaining structure of the stable helium core and therefore, the second ionization energy of beryllium is about 1757 kJ/mol, which is low compared to helium
For fluorine, we have;
F⁺ = [He] 2s² 2p⁴⁺
Therefore, the second ionization of fluorine remains high due to the increased attraction of the positively charged fluorine ion for electrons than electrically neutral fluorine atom that has equal number of protons and electrons such that the second ionization energy of fluorine is higher than the first ionization energy and is about 3357 kJ/mol
Therefore, the element that has the largest second ionization energy is lithium, Li.

Explanation:
As the human population grows, the size of cities increases. As cities grow, more land must be cleared to make way for homes, businesses, and roads. Which two events would be likely effects of replacing a forested area with an urban area? A. More air pollution because there are fewer trees to take in carbon dioxide B. Less erosion of soil as plants covering the ground are added to gardens C. Fewer birds and other wildlife because they have fewer places to live D. More trees because of increased solar energy in the area
Answer:1. Introduction
The main air pollutants are represented by gases forms, particles in suspension, different ionizing radiation and noise.
The gases forms are: oxidized and reduced forms of carbon (CO2, CO, CH4), of nitrogen (NO2, NO, N2O4, NH3, NH4+), SO2, O3, C6H6 vapours, Hg, volatile phenols, Cl2, etc.
The particulate forms are: PM10 and PM2.5 particulate matter, heavy metals with toxic effect (Pb, Ni, Cd, As), polycyclic aromatic hydrocarbons PAHs, etc.
Atmospheric pollutants have a negative effect on the plants; they can have direct toxic effects, or indirectly by changing soil pH followed by solubilization of toxic salts of metals like aluminum. The particulate matters have a negative mechanical effect. They cover the leaf blade reducing light penetration and blocking the opening of stomata. These impediments influence strongly the process of photosynthesis which rate declines sharply.
Explanation:
Answer:
A More air pollution because there are fewer trees to take in carbon dioxide
C Fewer birds and other wildlife because they have fewer places to live

Explanation:
which diagram would it be?
Answer:
2CH4 ------> 3H2 + C2H2
Explanation:
The law of conservation of mass states that atoms can neither be created nor destroyed in a chemical reaction.
The implication of this law is that the number of atoms of each element on the reactant side must be equal to the number of atoms of each element on the product side.
This law is only obeyed by the reaction, 2CH4 ------> 3H2 + C2H2
There were eight atoms of H on the left hand side as well as the right and side of the reaction equation. There were two atoms of C on both the left and right hand sides of the reaction equation respectively. Hence, the law was obeyed here.

A certain chemical contains 46.30% chlorine, 47.05% carbon, 6.63% hydrogen. What is the molecular formula of the compound? The molar mass of the compound was determined to be 153.052g/mol.
C6H10CI2
C6H8CI2
C3H5CI
C4H4CI
C8H8CI2
Answer:
C6H10Cl2
Explanation:
Convert mass % to mass
100g of the compound contains from each elements: 46,3g Cl; 47,05g C and 6,63g H
Molar mass
Cl = 35.5 g/mol
C = 12 g/mol
H = 1 g/mol
Find the number of moles:
Chlorine: 46.4g /35.5g/mol = 1,3 moles
Carbon: 47,05g/12 g/mol = 3,92 moles
hydrogen: 6,63g/1g/mol = 6,63 moles
Molar fraction:
Cl = 1,30/ 1,30 = 1
C = 3,92/ 1,30 = 3,01
H = 6,63/ 1.30 = 5,01
C3H5Cl = 76,5 g/ mol x 2 = 153 g/ mol
So multiply the molecular formula by two = C6H10Cl2

a container with a volume of 2.5L contains air at a pressure of 0.5 atm. if the volume is reduced to 1.5L at constant temperature, what will be the resulting pressure of the air inside
Answer:
Final pressure of the air inside is 0.83atm
Explanation:
Boyle's law is the gas law that relates the change in volume when pressure change at constant temperature and vice versa. The equation is:
P₁V₁ = P₂V₂
Where P is pressure and V is volume of 1, initial state and 2, final state of the gas
Replacing:
P₁ = 0.5atm
V₁ = 2.5L
P₂ = ?
V₂ = 1.5L
P₁V₁ = P₂V₂
0.5atm*2.5L = P₂*1.5L
0.83atm = P₂
Final pressure of the air inside is 0.83atm
2. Based on what you know about waves and light, do you think that light can be
modeled as a wave? Explain why or why not.
Answer:
Light as a wave: Light can be described (modeled) as an electromagnetic wave. In this model, a changing electric field creates a changing magnetic field. This changing magnetic field then creates a changing electric field and BOOM - you have light. ... So, Maxwell's equations do say that light is a wave.

what displays the number of atoms, nature and bond types in organic compounds
Answer:
Structural formula
Explanation:
Various type of formulae describe an organic compound. The empirical formula only shows the ratio of atoms of each element present. The molecular formula shows the exact number of atoms of each element present.
Lastly, the structural formula shows us the arrangement of these atoms in space. It shows us the number of atoms, nature and bond types in organic compounds.
The structural formula enables us to picture what the real molecule must look like.
