Answer:

Oxidation states are used in chemistry solutions. It is a bond in which electron transfers easily from one nucleus to another nucleus.

Explanation:

Oxidation-reduction reactions have some rules.
The oxidation state is 0 at an uncombined bond.
The bond of oxidation reduction is +1 in alkeli metal.
The bond in two metal is +2
The oxidation reduction state at helogens is -1. It does not happened always.
The oxygen bond in oxidation and reduction is -2.
The sum of the oxidation state is equal to the compound charges.
In this process the changes occur for any elements. Redox could be occur. Its oxidized and reduction reaction can be seen in this process.

You've just solved a problem and the answer is the mass of an electron, me=9.11×10−31kilograms. How would you enter this number

mihalych1998 [28]

The mass of an electron can be expressed in the box as $\boxed{{m_e} = 9.1 \times {{10}^{ - 31}}{\text{ kg}}}$ .

Further explanation:

Atom is the smallest particle that can be present in any element. It is also known as the building unit of matter. Each atom has a central part that is known as the atomic nucleus. There are three subatomic particles that constitute the atom. These particles are protons, neutrons, and electrons. The atomic nucleus consists of protons and neutrons, both are collectively called nucleons. Electrons revolve around the nucleus of an atom in definite orbits.

Protons are positively charged subatomic particles, electrons are negatively charged and neutrons have no charge. Since electrons carry a unit negative charge, these create an electric field around them. These also participate in nuclear reactions. The mass of an electron $\left( {{m_e}} \right)$ is $9.1 \times {10^{ - 31}}{\text{ kg}}$ , that of protons is $1.6726219 \times {10^{ - 27}}{\text{ kg}}$ and that of neutrons is $1.674927471 \times {10^{ - 27}}{\text{ kg}}$ . The electrons are responsible for chemical properties of elements. The distribution and arrangement of electrons is used to predict whether the element will be inert or reactive.

Therefore the required answer is $\boxed{{m_e} = 9.1 \times {{10}^{ - 31}}{\text{ kg}}}$ .

How are beef and gas productions related to methane levels?<br><br> Plzzz answer quick

Reptile [31]

Answer:

Cows and other ruminant animals (like goats and sheep) emit methane, a potent greenhouse gas, as they digest grasses and plants. This process is called “enteric fermentation,” and it's the origin of cows' burps.
