1. An ionic bond is a bond in which (d) two ions are attracted to each other, because one atom has gained an electron and one has lost an electron, creating oppositely-charged ions.
2. A nonpolar covalent bond is a bond in which (c) two atoms share electrons equally, such that the atoms involved have no charge.
3. A polar covalent bond is a bond in which (a) two atoms share electrons unequally because one atom is holding the shared electrons closer to its own nucleus, creating a slight electronegative and electropositive charge on the atoms involved.
4. A hydrogen bond is a bond in which (b) two polar molecules are attracted to each other because one is slightly electropositive and one is slightly electronegative.
What is the correct definition of an ionic bond?
An ionic bond is formed by the complete transfer of some electrons from one atom to another. The atom losing one or more electrons becomes a cation—a positively charged ion. The atom gaining one or more electrons becomes an anion—a negatively charged ion.
What is Non-polar Covalent Bond?
A non-polar covalent bond is a type of chemical bond that is formed when electrons are shared equally between two atoms. Thus, in an atom, the number of electrons shared by the adjacent atoms will be the same.
What is a polar covalent bond?
A bond formed between two atoms with a difference in electronegativities by sharing electrons is called a polar covalent bond.

Red light has a wavelength of 6.80x10 2 nm. The energy of a photon of Red light is (in J) ? I keep getting 2.92e-19 but that's not the correct answer, it's 3.20e-19
A photon of red light with a wavelength of 6.80 x 10-7 m has an energy of 3.20 x 10-19 J.
A photon's energy is inversely correlated with its wavelength, and its frequency is inversely correlated with its energy. E = hf, where E is the photon's energy, h is Planck's constant (6.62607015 10-34 Js), and f is the photon's frequency, can be used to express this relationship.
E = hc/, where E is the energy, h is Planck's constant (6.62607015 10-34 Js), c is the speed of light in a vacuum (2.998 x 108 m/s), and is the wavelength of the photon, can be used to compute the energy of a photon.
We obtain the following equation by plugging in the above values:
E = (6.62607015 10-34 Js) * (2.998 x 108 m/s) / (6.80 x 10-7 m)

a solution is prepared by dissolving 170.1 g of glucose (c6h12o6) is dissolved in enough water to make 1.000 l of solution. the density of the solution is 1.062 g/ml. calculate the concentration in molality (m) and percent by mass.
Molality of the given solution is 0.000947 mol/kg and its mass percentage is 14.29%.
To calculate molality, we need to know the number of moles of solute (glucose) present in the solution.
Number of moles = mass of solute / molar mass of solute
Number of moles of glucose = 170.1 g / (6 x 12.01 + 12 x 1.01 + 6 x 16.00) = 170.1 g / (6 x 12.01 + 12 x 1.01 + 6 x 16.00) = 170.1 g / 180.18 g/mol = 0.947 moles
Molality (m) = number of moles of solute / mass of solvent (in kilograms) Molality = 0.947 mol / (1000 g / 1000 g/kg) = 0.000947 mol/kg
Percent by mass (mass %) = mass of solute / total mass of solution x 100 Percent by mass = (170.1 g / (1000 g + 170.1 g)) x 100 = 14.29%.

why doesn't the solution change color with addition of diethyl carbonate in a crystal violet reaction
The solution does not change color with the addition of diethyl carbonate in a crystal violet reaction because it does not interfere with the dye-base interaction.
In a crystal violet reaction, the dye crystal violet is dissolved in an acidic solution, where it exists as an ionized species. The addition of a basic compound, such as diethyl carbonate, can alter the pH of the solution and affect the ionization of the dye, potentially changing its color.
However, diethyl carbonate is a weak base that does not interfere with the dye-base interaction and therefore does not alter the color of the solution. This makes it useful as a solvent for crystal violet and other dyes, as it allows the color to be measured without interference from the solvent.

when the ph of a solution decreases from 11 to 8 the h3o concentration
The pH falls as the hydrogen ion concentration rises.
How does pH effect on ion concentration?Seven is the neutral pH. An increase in pH above 7 indicates an increase in alkalinity, whereas a fall in pH below 7 indicates an increase in acidity (hydrogen ions) (hydroxyl ions). Each pH unit corresponds to a concentration change of 10 times. The amount of hydronium in the solution rises as H+ ions separate from the acid and unite with water to create hydronium ions. A solution becomes less acidic and more basic as the hydronium concentration declines and the pH rises. We refer to a neutral solution with [H+]=10-7 as having a pH of 7. For instance, this indicates that a solution with a pH of 4 has a hydrogen-ion concentration of 10-4mol/l, or 0.0001 mol of hydrogen ions per liter of the solution.
The hydrogen ion concentration's negative log is known as pH. pH1 is the acidic range. Highest on the scale and very basic is pH 14. However, by comparing two H+ concentrations, we may observe what is taking place:
Since the log of [H+] = 1x10-10 is -10 and there is a negative sign to make it positive, the pH at this concentration is 10.
The pH is -log(10-2), or 2, at larger concentrations, such as 1x10-2 or more. [H3O+] = 10-pH So for pH = 11 , [H3O+] = 10-11 M ,and for pH = 8 , [H3O+] = 10-8.

a. 1:10
b.10:1

The pH of a solution can be calculated from the concentration of hydrogen ions [H+]. So the correct answer is d) 2:1.
How to calculate ratio of concentration of acetic acid and acetate ions?
The pH of a solution can be calculated from the concentration of hydrogen ions [H+]. The concentration of H+ ions in a solution of acetic acid (CH3COOH) and acetate (CH3COO-) ions can be calculated using the expression for the acid dissociation constant (pKa) of acetic acid:
pH = pKa + log([A-]/[HA])
Where [A-] and [HA] are the concentrations of acetate and acetic acid ions, respectively.
Since the pKa of acetic acid is 4.74, a solution with a pH of 5.74 would have [H+] = 10^(-5.74), and we can solve for [A-] and [HA].
For a 1:1 ratio of acetic acid and acetate ions, [A-] = [HA], and the equation becomes:
pH = pKa + log([A-]/[A-]) = 4.74
So a 1:1 ratio is not the correct answer.
For a 2:1 ratio, [A-] = 2[HA], and the equation becomes:
pH = pKa + log(2[HA]/[HA]) = 5.74
So the correct answer is d) 2:1.

Select the structure(s) for a compound with six carbon atoms that exhibit(s) the following feature: Only one carbon atom is sp hybridized, and the remaining five carbon atoms are all sp hybridized (remember that your compound can have elements other than carbon and hydrogen).
Answer:
The structure(s) for a compound with six carbon atoms that exhibit(s) the feature of only one carbon atom being sp hybridized and the remaining five carbon atoms being sp hybridized is cyclohexane. This can be determined by using the information from chegg.com, which states that cyclohexane is a compound with six carbon atoms that exhibit the feature of only one carbon atom being sp hybridized and the remaining five carbon atoms being sp hybridized.
Explanation:
A possible compound with the specified features is cyclohexene.
Cyclohexene is a six-carbon molecule with a single double bond, meaning that one carbon atom is sp2 hybridized while the rest are sp3 hybridized. This results in a planar structure with 120 degree angles between the bonds, which is consistent with sp2 hybridization. All five of the remaining carbon atoms in cyclohexene are sp3 hybridized, meaning they form tetrahedral structures. This results in a hexagonal ring structure in which the double bond is part of one of the sides of the hexagon.
When two atomic orbitals join to generate a hybrid orbital in a molecule, the energy of the individual atoms' orbitals is redistributed to give orbitals of equivalent energy. We refer to this process as hybridization.
