What type of central-atom orbital hybridization corresponds to each electron-group arrangement:
galina1969 [7]

Tetrahedral arrangement is resulted upon mixing one s and three p atomic orbitals, resulting in 4 hybridized sp^3 orbitals → sp^3 hybridization.

<h3>What is orbital hybridization?</h3>

In the context of valence bond theory, orbital hybridization (or hybridisation) refers to the idea of combining atomic orbitals to create new hybrid orbitals (with energies, forms, etc., distinct from the component atomic orbitals) suited for the pairing of electrons to form chemical bonds.

For instance, the valence-shell s orbital joins with three valence-shell p orbitals to generate four equivalent sp3 mixes that are arranged in a tetrahedral configuration around the carbon atom to connect to four distinct atoms.

Hybrid orbitals are symmetrically arranged in space and are helpful in the explanation of molecular geometry and atomic bonding characteristics. Usually, atomic orbitals with similar energies are combined to form hybrid orbitals.

Hurry!!!!!!!!!!!!!!! Match the terms to the correct descriptions.
viva [34]

The type of energies or the words in this item are matched with the given descriptions. The lists below are as follow.<span>

<span>a. The word that best match this description is MECHANICAL energy. In most sources, mechanical energy is described to be that energy that is possessed by an object with respect to its motion and position. </span>

<span>b. The answer to this item is LIGHT energy. This type of energy can be created through different means (i.e. radiation, chemical, and mechanical). This is the energy emitted by hot objects such as the sun, lasers, and bulbs.</span>

<span>c. The type of energy that is transferred by the movement of the electrons through a conductor is ELECTRICAL energy. The movement of the electrons along the line is commonly called as the current. Moreover, this is also a type of kinetic energy because of the movement of the electrons. Thus, the faster the movement of the electron the higher is the energy. </span>

<span>d. The type of energy that is stored in batteries or food is CHEMICAL energy. This type of energy is that which is stored in the bonds of the different chemical compounds. This is also most commonly released when reaction between elements/compounds happen.</span>

<span>e. The energy that travels through vibrations and waves is SOUND energy. As given above, this is associated with the movement or vibrations of the matter. This is also a type of mechanical energy because of the waves produced through to the vibrations.</span>

<span>f. The type of energy that is found in the nucleus and atoms is the NUCLEAR energy.  Nuclear reactions most often released this type of energy simultaneous with the generation of heat. </span>

<span>g. The stored energy is called the POTENTIAL energy. The equation for this energy is mgh where h is the height, pertaining to the position of the object. Once the object is released, it will be converted to other forms of energy. </span>

<span>h. The answer to this item is THERMAL energy. This type of energy can be transferred in three different ways: (1) conduction, (2) convection, and (3) radiation.</span></span>

How are muscles able to keep making energy even when no food is eaten and glucose levels are low?
erastova [34]

Although lipids hold the majority of the body's energy reserves, glycogen is the body's primary energy source.

Glucose is a polymer that makes up glycogen. Our body's primary source of energy is carbs. The remaining glucose in the body is turned into glycogen and stored in various places, but the majority of our body's energy reserves are found in fats, which are kept in the form of lipids.

Where does the energy come from in the muscles?

The chemical energy that is stored in our meals is used by muscles to produce heat and motion energy (kinetic energy). Energy is necessary for maintaining body temperature, promoting physical activity, and enabling tissue growth and repair. Foods high in protein, fat, and carbohydrates provide energy.

What Takes Place to Muscles in the Absence of Glucose?

Your body converts carbs, such as those found in bread or fruit, into glucose after consumption. Glycogen is the form of glucose that is stored in your muscles and liver and is used for energy when you are not eating or while you are exercising.
