The reactivity of fluorine can be explained from molecular orbital theory with the calculation of the bond order.
What is molecular orbital theory?The molecular orbital theory is assigned to explain the movement of the electrons in the bonding and anti-bonding orbitals.
The number of atom in the bonding and anti-bonding atomic orbits results in the elucidation of the bond order for the element.
The bond order and reactivity are inversely proportional to each other. The higher bond order depicts the presence of stronger bonds between the molecules and lower reactivity.
The bond order of fluorine atom is elucidated from the molecular orbital theory. The bond order of fluorine atom is 1, that explains the high reactivity of fluorine.

The density of gold is 19.3 g/cm³. What is the mass of 11.3 cm³ of gold?
Answer:
218.09g
Explanation:
the formula for density is mass/volume
you have volume so rlly what you have is 19.3g/cm3=m/11.3cm3
so mass equals density x volume
and 19.3 x 11.3 = 218.09

In terms of their chemical properties (such as how they react with things), how do the elements in a group compare to the other elements in that group? For example, Sodium (Na) and Potassium (K) are both in the same group, what does this mean about their chemical properties?
Answer:
Groups like the Halogens, which include Chlorine and Flourine, share similar properties both behaviorally and structurally. The Periodic Table is essentially a bunch of patterns and trends and the groups (like the one with Sodium and Potassium) were grouped together because of these similarities.

Summarize how C-14 and U-238 dating together can be used to determine fossil ages.
Answer:
Uranium 238 is only found in igneous or volcanic rocks. So no fossils can be dated directly using U 238.
Because of the huge differences in the half lives of Carbon 14 and Uranium238 they cannot be used together. Carbon 14 can only be used to date fossils of a very recent age. Uranium 238 can only be used to date volcanic rocks of a very old age.

the bonding between sodium and chlorine, why is it that type of bounding? what it creates? what happens in water when you put sodium chloride in water?
I need it quickly and not copy-write.
Answer:
NaCl sodium chloride is an ionic salt. Also commonly known as table salt. When you put sodium chloride in water, the molecule dissolves in water because the covalent bonds of water (H2O) is stronger than the ionic bond of NaCl.
Explanation:
To be more specific, the two hydrogen (+) molecules are attracted to the chlorine due to its negative charge. The oxygen (2-) of the water is also attracted to the Na (+). Water eventually pulls Sodium Chloride apart (breaks ionic bond) and dissolves it.

Answer:
Diatomic carbon (systematically named dicarbon and 1λ2,2λ2-ethene), is a green, gaseous inorganic chemical with the chemical formula C=C (also written [C2] or C2). It is kinetically unstable at ambient temperature and pressure, being removed through autopolymerisation. It occurs in carbon vapor, for example in electric arcs; in comets, stellar atmospheres, and the interstellar medium; and in blue hydrocarbon flames.[1] Diatomic carbon is the second simplest form of carbon after atomic carbon, and is an intermediate participator in the genesis of fullerenes.

What law does a balanced chemical equation demonstrate?
Answer:
The law of conservation of mass
Explanation:
A chemical equation is an expression of the net composition change associated with a chemical reaction. It shows how a certain amount of reactants yields a certain amount of products. Both of these amounts are measured in moles. Chemical equations often contain information about the state of the reactants: solid, liquid, gas, or aqueous. In addition, they always adhere to the law of conservation of mass, which holds that matter can change form, but cannot be created or destroyed.
The Lithium atom has only two energy levels. The third is empty. Therefore, we can refer to the second energy level of the lithium atom as the outermost level. The electrons in this outermost energy level are called valence electrons. Refer to the table you just constructed, and determine the number of valence electrons for the first 18 elements. Fill in the table with the identified number of valence electrons

which molecule is a common output of glycolysis, pyruvate oxidation, and the citric acid cycle?
Explanation:
Acetyl CoA links glycolysis and pyruvate oxidation with the citric acid cycle. In the presence of oxygen, acetyl CoA delivers its acetyl group to a four-carbon molecule, oxaloacetate, to form citrate, a six-carbon molecule with three carboxyl groups.
Acetyl Co-A is a common output of glycolysis, pyruvate oxidation and citric acid cycle.
How does acetyl co-A links glycolysis and citric acid cycle?Acetyl Co-A links glycolysis and pyruvate oxidation with the citric acid cycle as in presence of oxygen it delivers its acetyl group to four carbon molecule to form citrate a six carbon molecule with three carboxyl groups .
In the citric acid cycle, 2 carbons of acetyl group which were of acetyl Co-A are released in form of carbon dioxide a major product of cellular respiration. For each acetyl Co-A which enters citric acid cycle 2 carbon dioxide molecules are released.
The transition reaction is the conversion of 3-carbon pyruvate to 2- carbon acetyl co-A and 2 molecules of carbon dioxide.

Use the molecular formulas for Ethanol (C2H5OH), Oxygen (O2), Carbon Dioxide (CO2), Water (H2O), and the yield sign () to write a balanced chemical equation for the reaction:
To balance the equation we have to find a combination of coefficients for the species that make the number of each element on both sides of the equation equal.

Have your mother and father (or any adult man and woman) sing together on the same note, at the same pitch (not an octave apart). Write down any differences you can hear. Is one voice lower or higher sounding (even though they are singing the same pitch)? Are there other differences you can hear? Explain your results using the terms “overtones,” “frequency,” “pitch,” and “sound quality.”
Answer:
No one sounds the same in singing everyone has a different pitch, overtones, and sound quality. Now in some songs people harmonize together and that can sound the same in pitch but there are still different pitches and tones.
