Answer:
essentially through the use of keplers 3rd law comparing the proportionality of a planets squared versus cubed orbital patterns you can determine how fast a planet will orbit something and complete a full orbit
Explanation:
Kepler's Third Law: the squares of the orbital periods of the planets are directly proportional to the cubes of the semi-major axes of their orbits. Kepler's Third Law implies that the period for a planet to orbit the Sun increases rapidly with the radius of its orbit. (from NASA)

Anions are the name for ions that have a negative charge. The body contains several common chemicals as ions. Sodium, potassium, calcium, chloride, and bicarbonate are typical examples.
What are anions ?Negatively charged electrons are called anion. When non-metals gain electrons, they are produced. They absorb one or more electrons. They have a negative charge overall as a result. The ion concentration iodide ( I- ), chloride ( Cl- ), and hydroxide are among examples ( OH– ).
The electrode where reduction takes place in any electrochemical cell is characterized as the cathode. On the other extreme, the positive electrode will draw anions, or negative ions, to itself.
Thus, when an atom obtains electrons, it transforms into the negatively-charged ion known as an anion.

In the malate-aspartate shuttle, _____ is reduced to _____ in the cytosol. oxaloacetate; malate aspartate; malate malate; aspartate malate; oxaloacetate aspartate; oxaloacetate
The malate-aspartate shuttle enables oxidative phosphorylation by allowing electrons to be moved across the inner membrane in the mitochondrion during glycolysis in eukaryotes.
In this malate-aspartate shuttle, oxaloacetate is reduced to malate in the cytosol.
During this biochemical system process, the cytosolic malate dehydrogenase which is the primary enzyme present in this shuttle system catalyzes the reaction of oxaloacetate and NADH to produce malate and NAD in the cytosol. This system enables oxidative phosphorylation in eukaryotes.Learn more: https://brainly.com/question/17216910

2. Which of the following statements is true about covalent bonding?
A It is the attraction of atoms for an electron
B it involves the losing and gaining of electrons
Cit involves the sharing of electrons
Dit involves the moving of electrons between energy levels
Answer:
C. it involves the sharing of electrons
Explanation:
A covalent bond consists of the mutual sharing of one or more pairs of electrons between two atoms. These electrons are attracted by the two atomic nuclei. A covalent bond forms when the difference between the electronegativities of two atoms is too small for an electron transfer to occur to form ions.

What type of bond would be formed between hypothetical elements X and Y in the the compound XY based on their electronegativity difference?
A. Nonpolar covalent because the difference in electronegativity is greater than 0.4, but less than 1.7
B. Nonpolar covalent because the difference in electronegativity is greater than 1.7
C. Polar covalent because the difference in electronegativity is greater than 0.4, but
less than 1.7
D. lonic because the difference in electronegativity is greater than 0.4, but less than
1.7
The bond is polar covalent because the difference in electronegativity is greater than 0.4, but less than 1.7.
Electronegativity refers to the ability of an atom in a compound to attract the electrons of the bond towards itself. It is a periodic trend that increases across the period but decreases down the group.
The electronegativity difference between the two atoms as shown in the question is 1.55. This means that the bond is polar covalent because the difference in electronegativity is greater than 0.4, but less than 1.7.

(6) Predict the number of valence electrons for each of the following elements (4 pts)
(a) P
(b) Ar
(c) c
(d) Ni
Answer:
P = 5, Ar = 8, C = 4, Ni = 2
Explanation:
All these answers can be based off which column of the periodic table each element is in. This does exclude the transition medals in between the 2nd and 13th columns. Column 1 = 1, Column 2 = 2, Column 3 = 3 and so on. Transition metals can be determined based on their electron configuration, which in this case, Ni has 2 electrons in its outer most shell.

How does collision theory relate temperature to the rate of a reaction?
Answer:
Explanation:
The collision theory explains why reactions occur between atoms, ions, and molecules. With the increase in temperature, there is an increase in the number of collisions. Increasing the concentration of a reactant increases the frequency of collisions between reactants and will, therefore, increase the reaction rate.

"Solution is a homogeneous mixture" explain
Answer:
solution is equal distribution of a solute and liquid
Explanation:
for example water and sugar make a solution
Solutions with a uniform composition are homogeneous solutions. A homogeneous solution, then, has an equal concentration of the constituent substances throughout the entire solution.
Similar to how water molecules are evenly distributed among the Na+ and Cl- ions when sodium chloride dissolves in it. The mixture's composition is constant throughout, and it is difficult to separate the components from one another. Solutions are homogeneous mixtures, which can contain substances in either state (solid, liquid, or gas).
Even if the components were evenly dispersed, they could still be separated at some point in a homogeneous mixture. The components may need to be separated using a procedure like evaporation, distillation, or chromatography, but this is still possible.

What is the empirical formula of a compound that is 27.3% carbon, 9.10% hydrogen and 63.6% nitrogen by mass?
Explanation:
Mass ratio C : H : N = 27.3 : 9.10 : 63.6
Mole ratio C : H : N = 27.3/12: 9.10/1 : 63.6/14
( Divide the mass ratio by their molar masses to find the ratio between moles)
Mole ratio = 2.275 : 9.10 : 4.54
= 2.275/2.275 : 9.10/2.275 : 4.54/2.275
= 1 : 4 : 2
Answer is CH4N2
The empirical formula of a compound is [tex]CH_4N_2[/tex]
What is an Empirical Formula?The empirical formula of a chemical compound is defined as the simplest whole number ratio of the atoms present in a compound.
The empirical formula of a compound defines the simplest ratio of the number of different atoms present. The molecular formula gives the actual number of each different atom present in a molecule. The molecular formula is mainly used which is a multiple of the empirical formula.
Molecular Formula = n × Empirical Formula
For above given example,
Mass ratio C : H : N = 27.3 : 9.10 : 63.6
Mole ratio C : H : N = 27.3/12: 9.10/1 : 63.6/14
( We divide the mass ratio by their molar masses to find the ratio between moles)
Mole ratio = 2.275 : 9.10 : 4.54 = 2.275/2.275 : 9.10/2.275 : 4.54/2.275
= 1 : 4 : 2
