Generally, a solution of an organic compound in water will be electrically?
a. nonconductive, b. highly conductive, c. charged, d. highly ionized, e. insulated

Answers

Answer 1

A solution of an organic compound in water will generally be nonconductive. Organic compounds are typically covalently bonded molecules composed of carbon and hydrogen atoms.

Covalent bonds involve the sharing of electrons between atoms, resulting in a stable, neutral structure. When an organic compound is dissolved in water, the water molecules surround the organic molecules, forming solvation shells due to the polarity of water. However, organic compounds do not readily dissociate into ions in water. Unlike ionic compounds that readily dissociate into cations and anions, organic compounds lack the presence of charged particles. Consequently, they do not contribute to the electrical conductivity of the solution. Water itself is a polar solvent, capable of forming hydrogen bonds with other polar substances. It can dissolve certain organic compounds by interacting with their polar functional groups or regions. Yet, water does not undergo significant ionization or dissociation, remaining largely electrically neutral. Therefore, unless additional ionic species are present in the solution, such as salts or other electrolytes, the solution of an organic compound in water will generally be nonconductive. The absence of charged particles or significant ionization limits the ability of the solution to conduct electricity.

Justify any assumptions you make. c. % ionization is defined as the ratio of the ionized acid concentration to the initial acid concentration x 100%. Determine the % ionization for the solution of acetylsalicylic acid in b. above

Answers

a. Acetylsalicylic acid is a weak acid because it dissociates only partially in water.

b. The expression for Ka for acetylsalicylic acid is

Ka = [H+][C9H7O4O-]/[C9H8O4].

The ionization of acetylsalicylic acid is,

                    C9H8O4    +     H2O  ⇌     H3O+   +  C9H7O4O-

Initial               0.20 M                                0                  0

Change              - x                                     + x              + x

Equilibrium     0.20 - x                                x                   x

The value of Ka for acetylsalicylic acid is 3.0 × 10-4.

Ka = [H+][C9H7O4O-]/[C9H8O4]= 3.0 × 10-4

[H+]^2/[C9H8O4] = 3.0 × 10^-4 × [0.20 - x]

The ionization constant expression is solved for the value of x using the quadratic equation,

0.60 x 10-4 = x^2

               x = 0.0077 M

[H+] = 7.8 × 10-4

The percentage of ionization is,

% ionization = (x/[C9H8O4]) × 100

                    = (0.0077/[0.20]) × 100

                    = 3.85%

Therefore, the % ionization for the solution of acetylsalicylic acid is 3.85%.

A system gains 652 kJ of heat, resulting in a change in internal energy of the system equal to +241 kJ. How much work is done?

Answers

Answer:

-411 kj

Explanation:

We solve by using this formula

∆U = ∆Q + ∆W

This formula is the first law of thermodynamics

Change in internal energy U = +241

Heat gained by system Q = 652

Putting the value into the equation

+241 = 652 + W

Workdone = 241 - 652

Workdone = -411 kj

Since work done is negative it means that work was done by the system

given the following experimental data, find the rate law and the rate constant for the reaction nh4 no2 -> n2 2 h2o rate = k {nh4 ] ^ [no2]

Answers

The rate law for the reaction is `rate = k[NH4][NO2]` and the rate constant is `k = 0.004 M^-2 s^-1`.

The rate law for the reaction:

`NH4NO2 -> N2 + 2H2O` is `rate = k[NH4NO2]`.

Given that the reaction is first order with respect to both NH4 and NO2, it can be written as `rate = k[NH4][NO2]`. The rate constant k is calculated by plugging in the rate data from the experiment and solving for k.

Example of how to solve for the rate constant k:

Suppose the following rate data was obtained in an experiment where the concentration of NH4 and NO2 were varied:| Experiment | [NH4] (M) | [NO2] (M) | Rate (M/s) || 1 | 0.1 | 0.2 | 4.0x10^-4 || 2 | 0.2 | 0.2 | 8.0x10^-4 || 3 | 0.2 | 0.1 | 4.0x10^-4 |Substituting the given data into the rate law:

Experiment 1: 4.0x10^-4 = k(0.1 M)(0.2 M) = 0.002 k

Experiment 2: 8.0x10^-4 = k(0.2 M)(0.2 M) = 0.008 k

Experiment 3: 4.0x10^-4 = k(0.2 M)(0.1 M) = 0.002 k

Taking the average of the three k values:

k = (0.002 + 0.008 + 0.002)/3 = 0.004 M^-2 s^-1

Therefore, the rate law for the reaction is `rate = k[NH4][NO2]` and the rate constant is `k = 0.004 M^-2 s^-1`.

is mixing colored light (like using this equipment in this lab) the same as mixing colored paint (as if you were mixing actual paint together)?

Answers

The mixing of colored light and colored paint follows different color models and produces different outcomes due to the properties of light and pigments.

Mixing colored light and mixing colored paint are not the same. When mixing colored light, such as using equipment in a lab, the primary colors are red, green, and blue (RGB). By combining different intensities of these colors, you can create various shades and hues. Mixing all three primary colors at full intensity produces white light.

On the other hand, mixing colored paint involves using the subtractive color model. The primary colors are cyan, magenta, and yellow (CMY). When you mix paints, the pigments absorb certain wavelengths of light, and the reflected light determines the perceived color. Mixing all three primary colors in paint results in a dark, muddy color, not white.

1. How many moles are in 24.6 grams of NaCl?

If someone could give an explanation along with an answer that would be appreciated :)

Answers

The gram to mole conversion is pretty simple. First you need to find the molar mass of the compound. The way you do that is take the combined atomic mass and convert it to grams (that’s mass of a single mole of that compound). For this example sodium’s atomic mass is 22.9 amu and chlorine’s is 35.45 amu. The molar mass of sodium chloride is those two number combines IN GRAMS.

22.99g + 35.45g = 58.44g

Now to find out 24.6g of Sodium Chloride you will divide the number of grams in a problem by the molar mass.

how many electrons are in the cyclobutadiene molecule shown below?

Answers

There are 20 electrons in the cyclobutadiene molecule shown in the image.

Cyclobutadiene is a molecule that contains 4 carbon atoms and 4 hydrogen atoms. The chemical formula for cyclobutadiene is C4H4. It is a highly reactive molecule and is unstable in its pure form. It has a square planar shape, and each carbon atom is bonded to two neighboring carbon atoms and one hydrogen atom.

Each carbon atom in cyclobutadiene has four valence electrons, and each hydrogen atom has one valence electron. Valence electrons are the outermost electrons in an atom and are involved in chemical bonding. The number of valence electrons in an atom is determined by the group number in the periodic table.

Carbon is in group 14, so it has 4 valence electrons. Hydrogen is in group 1, so it has 1 valence electron. The total number of valence electrons in cyclobutadiene is calculated by adding the valence electrons of all the atoms.

4 carbon atoms x 4 valence electrons per carbon atom = 16 valence electrons4 hydrogen atoms x 1 valence electron per hydrogen atom = 4 valence electrons Total number of valence electrons = 16 + 4 = 20Therefore, there are 20 electrons in the cyclobutadiene molecule shown in the image.

2. sublimation, followed by deposition

Following the dashed line at 1 atm of pressure on the phase diagram from 100 to 500 °C, the phase changes that will occur are sublimation, followed by deposition.

At lower temperatures, the substance will undergo sublimation, transitioning directly from the solid phase to the gas phase. As the temperature increases, the substance will exist as a gas.

However, at higher temperatures, as the temperature decreases again, the gas will undergo deposition, transitioning directly from the gas phase back to the solid phase.

Therefore, the substance will experience sublimation and deposition as the temperature changes within the specified range, without undergoing melting or vaporization.

a. average molecular speed
b. density
c. average molecular kinetic energy
d. number of molecules present

Answers

The number of molecules present is the only quantity that will be the same for both flasks. The quantity that will be the same for both flasks is:

d. number of molecules present

The number of molecules present in each flask is determined by the ideal gas equation, which states that the number of molecules (n) is proportional to the product of the pressure (P), volume (V), and the inverse of the temperature (T):

PV = nRT

Since the two flasks have the same volume, the number of molecules present will be the same if the temperature and pressure are also the same.

However, for the other quantities listed:

a. average molecular speed: The average molecular speed of a gas is directly proportional to the square root of the temperature. Since the temperatures in the two flasks are different (0°C and the other temperature is not specified), the average molecular speeds will be different.

b. density: The density of a gas is determined by its molar mass and pressure. Since [tex]H_2[/tex] and [tex]CO_2[/tex] have different molar masses, their densities will be different even if the pressures are the same.

c. average molecular kinetic energy: The average molecular kinetic energy of a gas is directly proportional to the temperature. Since the temperatures in the two flasks are different, the average molecular kinetic energies will be different.

Therefore, the number of molecules present is the only quantity that will be the same for both flasks.
