divide the compounds below into electron-poor and electron-rich groups.

Answers

Answer 1

The electron-poor groups are the ones that make up the majority of the electrons in the material.

This is why it is critical that you divide compounds by the number of electrons they contain. In other words, if you have a compound with two electrons, you want to look at the two-electron group, not the three-electron group. So, if you have a compound with two electrons, you should look at where the two electrons are rather than where they were. Start with the group containing the two electrons and work your way down. Essentially, we want to divide compounds into three groups, three electron groups. The first group has a low electron density, the second has a high electron density, and the third has no electrons. The first group is the easiest to distinguish, but you can see that the first group contains the most electron-rich compounds. The second group is more difficult to distinguish. Because the compounds in the group will have two electrons, it is electron rich. The third group is the most difficult to enter, and it's clear that the second group contains the most electron-free compounds.

oxygen is estimated to make up 28.7% of the mass of ordinary matter on earth, while magnesium makes up 15.4%. estimate the ratio of the number of oxygen atoms to the number of magnesium atoms on earth. 2.82 2.88 3.22 2.73

Answers

In the given question, option a. 2.82 is the predicted ratio of the amount of oxygen atoms to the number of magnesium atoms on Earth.

Matter is anything that has mass and takes up space. It can exist in different forms, such as solid, liquid, or gas, and it is made up of tiny particles called atoms.

To estimate the ratio of the number of oxygen atoms to the number of magnesium atoms on earth, we need to compare the mass percentage of each element with their atomic masses.

The atomic mass of oxygen is 16, while the atomic mass of magnesium is 24.31.

The mass percentage of oxygen is 28.7%, so the mass of oxygen in 100 grams of ordinary matter is 28.7 grams.

The mass percentage of magnesium is 15.4%, so the mass of magnesium in 100 grams of ordinary matter is 15.4 grams.

The number of oxygen atoms in 28.7 grams of oxygen is (28.7 g / 16 g/mol) = 1.79 moles of oxygen.

The number of magnesium atoms in 15.4 grams of magnesium is (15.4 g / 24.31 g/mol) = 0.634 moles of magnesium.

The ratio of the number of oxygen atoms to the number of magnesium atoms: [tex]\rm \dfrac {(1.79 \ moles\ of \ oxygen)} { (0.634\ moles \ of \ magnesium) }[/tex]

= 2.82

Therefore, the estimated ratio of the number of oxygen atoms to the number of magnesium atoms on earth is option a. 2.82.

by what factor is the rate of a reaction changed if an enzyme lowers the ea by 7.0 kj/mol at 37°c?

Answers

32.9 times is the rate of a reaction changed if an enzyme lowers the Ea by 7.0 kj/mol at 37°C.

Using the Arrhenius equation

log (k2/k1) = [Ea (uncatalysed) - Ea (catalysed)] / 2.303x RT

where k2 = rate constatnt of catlaysed reaction

         k1 = rate constant of uncatalysed reaction

         R = gas constant = 8.314 J/mol.K

         T = absolute temperature of the reaction

            = 37 + 273 = 310 K

thus

log (k2/k1) = 9x1000J / (2.303 x 8.314x310)

               = 1.51

thus k2/k1 = 32.81

The rate at which a chemical reaction occurs is defined as proportional to the rise in product concentration per unit time and the decrease in reactant concentration per unit time. The reaction times may vary substantially.

For example, although oxidative corrosion of iron in the Earth's atmosphere might take years, cellulose burning in a fire happens in fractions of a second. Most responses slow down as the reaction develops.

this question is related to set of equations,

The vertex of f(x) = (x-6)(x+2) is as follows:-

For any equation of the type y = ax^2 + bx + c, the vertex is given by (h, k).

Where, h = -b/2a and k = (4ac - b^2)/4a.

Given, the equation is f(x) = (x - 6)(x + 2)

f(x) = x^2 - 6x + 2x - 12

f(x) = x^2 - 4x - 12

Here, a = 1, b = -4 and c = -12

so, h = -(-4)/2(1)

h = 4/2

h = 2

4ac = 4(1)(-12)

4ac = -48

So, k = [-48 - (-4)^2]/4(1)

k = (-48 - 16)/4

k = -64/4

k = -16

Therefore, the vertex is (h, k) = (2, -16).

which of the following best represents the structure of an amino acid in basic solution (ph = 11)?

Answers

Organic compounds that contain alike amino as well as carboxylic acid functional groups are known as amino acids.

Although thousands of amino acid residues exist in nature, the alpha-amino acids that comprise proteins are unquestionably the most important. The genetic code contains only 22 alpha amino acids.

An amino acid's structure allows it to function as both a base and an acid. Because nearly all amino acid molecules exist as zwitterions at a specific pH value (different for each amino acid), an amino acid has this ability. When acid is added to a zwitterion-containing solution, the carboxylate group manages to capture a hydrogen (H+) ion, causing the amino acid to become positively charged.

When a base is added, the ion removal of the H+ ion from the zwitterion's amino group results in a negatively charged amino acid. In both cases, the amino acid serves to maintain the pH of the system by removing the added acid (H+) or base (OH) from solution.

All of these orbitals therefore combine in one gigantic band of delocalized orbitals that spans the entire crystal with its myriad atoms. This band is only partly filled and the difference in energy between one state and the next is puny, which explains copper’s outstanding conductive properties.

Beryllium and iodine do not react to form a compound. The chemical formula for beryllium is Be and the chemical formula for iodine is I. Calcium and iodine can react to form calcium iodide, which has the chemical formula CaI2.

In a chemical reaction, atoms can rearrange themselves to form new compounds by bonding together. The number and type of atoms in the reactants (the starting substances) must be balanced with the number and type of atoms in the products (the substances formed in the reaction). This balance is expressed through the use of chemical formulas.

In the case of beryllium and iodine, there is no chemical reaction that occurs between these two elements. Therefore, the chemical formula for this combination would simply be the symbols for beryllium (Be) and iodine (I) side by side, with no subscripts or other notation indicating a chemical bond between them.

On the other hand, calcium and iodine can react to form calcium iodide, which is a compound made up of calcium and iodine atoms bonded together. The chemical formula for calcium iodide is CaI2, which indicates that there is one calcium atom (represented by the symbol Ca) and two iodine atoms (represented by the symbol I) in each molecule of calcium iodide.

According to the Brnsted-Lowry acid-base theory, a conjugate acid is a chemical that is produced when an acid donates a proton (H +) to a base; in other words, it is a base that has had a hydrogen ion added to it, as in the opposite reaction, the base loses a hydrogen ion. A base is made when a proton from an acid is taken on, while an acid is produced when a base accepts one. An acid and a base that only differ by the presence or absence of a proton are said to be conjugate acid-base pairs.

Intermolecular forces are all some kind of: lecture 9

Answers

All intermolecular forces include electrostatic attraction in some way.

Electrostatic interactions are the source of intermolecular forces; this means that they are created when positively and negatively charged species come into contact with one another. Intermolecular interactions, much like covalent and ionic bonds, are the result of the addition of components that are both attractive and repulsive. The electromagnetic forces of attraction or repulsion that act between atoms and other types of neighboring particles, such as atoms or ions, are examples of intermolecular forces, also known as secondary forces. An intermolecular force, also known as an IMF (or secondary force), is the force that mediates the interaction between molecules.

which one or more of the three decay processes (α, β-, or γ) results in a new element?

Answers

α and β decay processes new elements.

The process by which unstable nuclei of radioactive atoms are becoming stable by emitting positive ions and energy is known as radioactive decay. Radioactive decay is classified into three types: alpha decay, beta decay, and gamma decay. Alpha and beta decay are processes that convert one element into another.

There seem to be three types of decays: α - decay, β – decay and γ – decay.

The nucleus loses two protons and two neutrons during alpha decay, resulting in the formation of a new element with just an atomic number that is two less than the original atomic number.

The new atomic number = the initial atomic number - 2

The neutron inside the core decays into one proton and one electron during beta decay, and the electron is emitted as a beta ray while the proton remains inside the nucleus.

As a result, it generates a new element with an atomic number that is one higher than the original atomic number.

The new atomic number = the initial atomic number + 1.

There is no change throughout charge or mass in the nucleus during gamma decay. As a result, the atomic number remains constant.

As a result, only α decay and β decay produce new elements.
