Which represents the copernican model that is most similar to that of aristarchus?

jeyben [28]

The Copernican model that is most similar to that of Aristarchus is where the solar system shows the planets in their orbits around the sun in the order: Mercury, Venus, Earth with Moon, Mars, Jupiter, Saturn.

Aristarchus of Samos was a Greek astronomer who argued that the earth rotates on its axis and revolves around the sun. He had suggested a new theory that, if true, would make the universe much larger than was believed at the time. In the 16th century, Aristarchus inspired the Polish astronomer Nicholas in his Copernicus’s studies.

However, Copernicus later erased this reference, and Aristarchus' theory was not mentioned in the book published by him. Copernicus His model is the system of planetary motion maintained by Copernicus, in which the earth revolves once in a day and around the sun once in his year, while the other planets also has an orbit centered near the sun.

To what extent do covalent compounds conduct electricity?.

RUDIKE [14]

Answer:

A covalent bond is formed between non metal atoms, which combine together by sharing electrons. Covalent compounds have no free electrons and no ions so they don't conduct electricity

circle the correct terms for the reaction going from left to right. reactant a gains/loses and electron to become product B

Effectus [21]

The question requires one to indicate the correct terms for the reactant from left to right.

<h3>What is a reactant?</h3>

A reactant is a material that enters and changes during a chemical reaction.

1. Reactant A (Gains/Loses) and electron to become product B

To produce B, reactant A loses one electron. The loss of one electron from an atom causes the atom to be oxidized.

Reactant A gives an electron to NAD+ and is transformed to B+ in the given reaction there is an increase in the positive charge. As a result, reactant A is oxidized to produce B+.

2. NAD+ becomes reduced in the process of the reaction.

NAD+ receives the electron given to it by reactant A and is reduced to NADH. As a result, the positive charge of NAD+ decreases.

3. NADH is more reduced than NAD+

NAD+ receives an electron and becomes NADH. As a result, NADH is decreased more than NAD+

4. NAD+ is in the more oxidized state compared to NADH

NAD+ has a surplus of positive charge as opposed to NADH. NAD+ must receive one electron in order to produce NADH. As a result, as opposed to NADH, NAD+ is more oxidized.

5. Reactant A is the electron donor in this reaction.

Reactant A loses one electron, resulting in positively charged B+. This electron is taken up by NAD+, which reduces to NADH. As a result, the electron donor is reactant A.

6. Reactant A is the reducing agent in this reaction.

A reducing agent is a molecule that can transfer electrons.

Such a molecule has the potential to decrease another molecule while also becoming oxidized. Reactant A is the reducing agent in the given reaction, donating an electron to NAD+.

Following the electron transfer, reactant A is oxidized to product B+, and NAD+ is reduced to NADH.
