How does an animal use sugar as a source of energy?

Answers

Plants and animals use glucose as a soluble, easily distributed form of chemical energy which can be 'burnt' in the cytoplasm and mitochondria to release carbon dioxide, water and energy. Pure monosaccharides, such as glucose, attract water.

An animal's body breaks down carbohydrates and converts them into simple sugar such as glucose. Glucose in the form of energy is carried through the blood and delivered to every cell of the body.

What is the function of sugar in animals?

Carbohydrates are an important compound of all life on this planet. Both plants and animals utilize carbohydrates as a source of energy to keep their body functioning at the most basic level.

Carbohydrates fulfill needs by helping in the synthesizing of other chemicals and giving structure to cells within the body. Carbohydrates are carrying out normal functions such as growth, movement, and metabolism.

Carbohydrates store energy in the form of starch and provide either simple or complex sugars. Polysaccharides, give a steady supply of energy while sugars, monosaccharides, and disaccharides, supply quick energy on dissolving.

Carbohydrates have the side effect of helping with the processing of other body's chemicals. As carbohydrates break down, they release energy.

A solution is prepared by dissolving 15.0 g of table salt in 70.0g of water. Find(a) the mass percent of solute and (b) the mass percent of solvent. ​

Answers

Answer:

[(15g NaCl/(70+15)]*100 = % NaCl

{(70g H2O/(70+15)]*100 = % H2O

Explanation:

A solution is prepared by dissolving 15.0 g of table salt in 70.0g of water. (a) The mass percent of solute is 17.64 % and (b) The mass percent of solvent is 82.35 %.

How to calculate the Mass percent of solute ?

Mass percentage = [tex]\frac{\text{Mass of solute}}{\text{Mass of solute + Mass of solvent}}[/tex]  × 100

How to calculate the Mass percent of solvent ?

Mass percentage = [tex]\frac{\text{Mass of solvent}}{\text{Mass of solute + Mass of solvent}}[/tex] × 100

Here,

Mass of solute (table salt) = 15.0 g

Mass of solvent (water) = 70.0 g

(a) The mass percent of solute

Put the value in above formula we get

Mass percentage = [tex]\frac{\text{Mass of solute}}{\text{Mass of solute + Mass of solvent}}[/tex] × 100

                             = [tex]\frac{15}{15 + 70}[/tex] × 100

                             = [tex]\frac{15}{85}[/tex]  × 100

                             = 17.64 %

(b) The mass percent of solvent

Mass percentage = [tex]\frac{\text{Mass of solvent}}{\text{Mass of solute + Mass of solvent}}[/tex] × 100

                             = [tex]\frac{70}{15 + 70} \times 100[/tex]

                             = [tex]\frac{70}{85} \times 100[/tex]

                             = 82.35 %

Thus, we can say that (a) The mass percent of solute is 17.64 % and (b)  The mass percent of solvent is 82.35 %.

elements of the fourth period fill the 4s sublevel with electrons before filling the 3d sublevel. Also, some elements move an electron from a filled 4s sublevel to an unoccupied 3d sublevel. Explain these behaviors

Answers

Answer:

Elements fill the lowest energy subshells first(Aufbau's rule), and the 4s subshell is lower energy than the 3d, making the labeling deceiving. In some rare situations, the electrons would rather have Hund's rule be respected more, having all electrons facing one way with no doubled up because it is more stable(these are pretty rare and usually deal with transition metals like copper).

Hope this helps!

Explanation:

As it has less energy than the 3d orbital, the 4s orbital fills next. Following the filling of the electrons, 4s has more energy than 3d. Therefore, the two electrons in the 4s are at a higher energy than they could be in the 3d since it has a vacancy. As a result, electrons transition from a higher to a lower energy orbital.

What are electrons ?

The elementary electric charge of the electron is a negative one, making it a subatomic particle. Due to their lack of components or substructure, electrons, which are part of the lepton particle family's first generation, are typically regarded to be elementary particles.

Since 4s electrons are bound by the nucleus farther away and more loosely than 3d electrons, 4s electrons are eliminated first rather than 3d electrons.

The 4s orbital should always be filled before the 3d orbitals, according to the Aufbau principle, although this isn't the case for the majority of elements. After Sc, electrons actually enter the 3d orbitals first because they have a lower energy than the 4s orbital.

Thus, electrons transition from a higher to a lower energy orbital.

Answers

Answer:

it is because of Dark Matter

Dark Matter, component of the universe whose presence is discerned from its gravitational attraction rather than its luminosity. Dark matter makes up 30.1 percent of the matter-energy composition of the universe; the rest is dark energy (69.4 percent) and “ordinary” visible matter (0.5 percent).

Dark matter is composed of particles that do not absorb, reflect, or emit light, so they cannot be detected by observing electromagnetic radiation. Dark matter is material that cannot be seen directly.

A group of scientists is studying observable matter in a cluster of galaxies. The duster remains intact due to the gravitational pull.

What is a galaxy?

A galaxy is a collection of stars, stellar remains, interstellar gas, dust, and dark matter that are gravitationally bonded together.

Dark matter is a component of the universe whose gravitational pull can be detected rather than its luminosity. The universe's matter-energy ratio is made up of 30.1 percent dark matter, 69.4 percent dark energy, and “regular” visible matter (0.5 percent).

Since dark matter is made up of particles that do not absorb, reflect, or emit light, it is impossible to identify it through electromagnetic radiation observation. Dark matter is a substance that cannot be directly observed.

Therefore, a team of researchers is examining the material that can be seen in a clump of galaxies. Due to the gravitational force, the duster is unharmed.

Every element has a set of particular characteristics. Each has a unique atomic and mass number because they contain a different ratio of protons and neutrons. The number of protons in an element mirrors the element's atomic number. The mass number equals the sum of the element's protons and neutrons.

According to increasing atomic numbers, chemical elements get organized. Periods and groups are the names of the horizontal rows and vertical columns, respectively. The chemical characteristics of elements within the same group are comparable due to their similar valency and number of outer electrons.

metallic bonding in a group three metal

Answers

Answer: In a pure metal, there are atoms that are surrounded by free moving valence electrons in which they move from one part of metal to another part . There for we can conclude that pure metals are held together by things called metallic bonds and due to attraction between the mobile valence electrons and the positively charged metal ions.

Explanation:

The ability to be drawn into thin sheet is called malleability. The ability to be drawn into thin wires is called ductility. Therefore, the metallic bonds is between metals and metals.

What is metallic bonding?

Metallic bonding is a type of chemical bonding that rises from the electrostatic attractive force between conduction electrons and positively charged metal ions.

Covalent bonds are not strong bond. They can not have malleability and ductility. Ionic bonds are very strong bond. These are too not malleable or ductile. Lewis structure is used to show valence electron of every element in a molecule so, it has nothing to do with malleability and ductility. Due to metallic bonding, there is high melting and boiling point.

Therefore, the metallic bonds is between metals and metals.
