Answers

Carbon is found in various forms on the Earth.It occurs in the elemental form as diamond and graphite, in the combined state as carbon dioxide, carbonate and bicarbonate salts in various minerals, while all biotic factors are based on carbon-containing molecules like carbohydrates, proteins, fats, nucleic acids and vitamins. The endoskeletons and exoskeletons of various animals are also formed from carbonate salts. Carbon is incorporated into life-forms through the process of photosynthesis which is performed in the presence of Sunlight by all life-forms that contain chlorophyll.Photosynthesis converts CO2 from the atmosphere or dissolved in water into glucose molecules.These glucose molecules are either converted into other substances or used to provide energy for the synthesis of other biologically important molecules.The utilisation of glucose to provide energy to living things involves respiration in which oxygen may or may not be used to convert glucose back to carbon dioxide.This CO2 goes back into the atmosphere.This is the broad outline of carbon cycle.

relative to electrons and electron states, what does each of the four quantum numbers specify

Answers

Answer:

(n, l, m sub l, m sub s)

N: principle quantum number (1,2,3,4,etc)

l: angular momentum quantum number, the shape (l has to be at least 1 less than n, but can be 0 depending on n)

M sub l: magnetic quantum number (l determines this number)

M sub s: spin quantum number (can only ever be 1/2 or -1/2)

Explanation:

The principle, azimuthal, magnetic, and spin quantum numbers specify the principle shell, the shape of the orbital, the number of orbitals, and electron spin respectively.

What are the quantum numbers?

The set of numbers that describes the position and energy of the electron are called quantum numbers. Four quantum numbers are principal, azimuthal, magnetic, and spin quantum numbers.

Principal quantum numbers (n) designate the principal electron shell of the atom and the most probable distance between the nucleus and the electrons. A larger value of the principal quantum number indicates a large distance between the electron and the nucleus.

The azimuthal quantum number (l) describes the shape of an orbital in which an electron is present. Its value is equal to the total number of angular nodes in that orbital.

The magnetic quantum number describes the total number of orbitals in a subshell and the orientation of these orbitals. The value of the spin quantum number (s) offers the direction in which the electron is spinning and it has only two possible values +½ and -½.

in an oxidation-reduction reaction, how is the reducing agent changed?

Answers

Explanation: The additional terminology comes from the definition that, within redox processes, a reductant transfers electrons to an oxidant; hence, the reductant (reducing agent) loses electrons, so is oxidized, while the oxidant (oxidizing agent) gains electrons, so is reduced.

In an oxidation-reduction reaction, the reducing agent loses electrons and loses potential energy, Therefore, option (C) is correct.

What is a reducing agent?

A substance that loses its electrons in a redox reaction to other substances and gets oxidized is called a reducing agent. A reducing agent is one of the reactants which reduces the other reactant by donating the electrons to the reactant of an oxidation-reduction reaction.

If the reducing agent can't pass electrons to another reactant in a reaction, then the reduction process does not occur and the reaction cannot proceed.

In redox reactions, when an electron loses potential energy as a result of the transfer and energy is released. Electrons with more potential energy are associated with less electronegative atoms and less potential energy is associated with a more electronegative atom (such as O).

Therefore, the reducing agent loses electrons and loses potential energy in a redox reaction.

assume that the volume is constant. At higher temp the gas molecules move faster and the pressure goes up.

P=kT

CONVERT C TEMP TO K TEMP FOR GAS PROBLEMS!!!!!!

108C = 108 +273 = 381 K

441C = 441 + 273 = 714K

P=kT

108 =k x 381

K=108/381 = 0.279

Which of the following particles are found in the nucleus of an atom? (Select all that apply).electronsprotonsneutronscompounds

Answers

Answer:

protons and neutrons

Explanation:

Neutrons and protons are the particles that are found in the nucleus of an atom.

What are protons and neutrons?

Protons and neutrons are subatomic particles. They are present in the nucleus of an atom and constitute most of the mass of the atom. There are three kinds of subatomic particles that are present in an atom.

These are -

Electrons: Electrons are negatively charged particles. These are present in the atomic shells of the atom. The number of electrons in the last shell of the atom constitutes the valency of the atom. Protons: Protons are positively charged particles. These are present in the nucleus of the atom.Neutrons: Neutrons are neutral molecules with no charge. These are also present in the nucleus of the atom.

Since most of the mass of the atom, in the form of protons and neutrons, is present in the nucleus, the mass number is denoted as the sum of the number of protons and neutrons. Protons and neutrons together are sometimes also called nucleons.

Therefore, neutrons and protons are present in the nucleus of an atom.
