Answer:

The statement that describes an electron is "It has a negative charge and is located in orbitals around the nucleus." Electrons are the smallest of the three particles that make up atoms

Explanation:

Electrons are found in shells or orbitals that surround the nucleus of an atom

Electrons are the sub-atomic particles that carry a negative charge over them. In the atom, the electrons are found in the orbitals or the shells around the nucleus. Thus, option D is correct.

Electrons are the smallest sub-atomic particle that has been known to carry a negative charge and are found in the orbitals of the atom. The charge carried by an electron is 1.602 x 10⁻¹⁹ coulomb and is small than the proton and neutron.

They revolve around the nucleus in their orbits and exhibit the properties of waves and matter. The number of electrons and protons are the same in a neutral atom which makes the atomic number.

Therefore, the electrons have been known to carry a negative charge that revolves in orbit around the nucleus.

If a solution is prepared by dissolving 16.30 g of ordinary sugar in 43.90 g of water. The boiling point of the solution is approximately 100.555 °C.

To calculate the boiling point of the solution, we can use the equation:
ΔTb = Kb * m
where ΔTb is the change in boiling point, Kb is the molal boiling point elevation constant, and m is the molality of the solution.

First, we need to calculate the molality of the solution. Molality (m) is defined as the number of moles of solute per kilogram of solvent. We have 16.30 g of sugar (sucrose) and 43.90 g of water, we need to convert these masses to moles. The molar mass of sucrose is 342.3 g/mol, so we can calculate the number of moles of sucrose:
moles of sucrose = mass of sucrose / molar mass of sucrose
= 16.30 g / 342.3 g/mol
= 0.0476 mol

Similarly, we can calculate the number of moles of water:
moles of water = mass of water / molar mass of water
= 43.90 g / 18.02 g/mol
= 2.437 mol

Now, we can calculate the molality of the solution:
molality (m) = moles of sucrose / mass of water (in kg)
            = 0.0476 mol / 0.0439 kg
            = 1.084 mol/kg

Next, we need to identify the molal boiling point elevation constant (Kb). The Kb value for water is 0.512 °C/m.
Now, we can calculate the change in boiling point (ΔTb):
ΔTb = Kb * m
= 0.512 °C/m * 1.084 mol/kg
= 0.555 °C

Finally, to identify the boiling point of the solution, we add the change in boiling point (ΔTb) to the normal boiling point of water (100 °C):
Boiling point of the solution = Normal boiling point of water + ΔTb
= 100 °C + 0.555 °C
= 100.555 °C

Answer for PLATO

Answer:

COOH is the carboxylic acid.

Answer:

Explanation:

The equation for frequency is:

\( \sf f = \dfrac{ \nu}{ \lambda} \)

Where:

f = frequency (Hertz), \( \nu\) = speed (343 m/s) and \( \lambda\) = wavelength (m)

Plugging the values,

\( \sf f = \dfrac{343}{0.78}\)

\( \sf f \approx 439.75 \: Hz\)

So The frequency of the given wave is 439.76 Hertz (approximately)

1. Fluid compressibility (C): Fluid compressibility refers to the measure of how much a fluid's volume changes in response to a change in pressure.

2. Solution-gas/liquid ratio (SGLR): The solution-gas/liquid ratio represents the volume of gas dissolved in a given volume of liquid at a specific pressure and temperature.

3. Fluid formation volume factor (FVF): The fluid formation volume factor represents the ratio of the volume of a fluid at reservoir conditions (pressure and temperature) to its volume at surface conditions.

4. Fluid densities (ρ): Fluid densities refer to the mass per unit volume of a fluid.

The respective concentrations of copper in the three solutions are 0.018 g/L, 0.012 g/L, and 0.0081 g/L.

The concentration of copper in the solutions can be determined using the Beer's law equation, A = εbc, where A is the absorbance, ε is the molar absorptivity, b is the path length, and c is the concentration.
First, we need to determine the molar absorptivity, ε, using the data from the standard solutions. We can rearrange the Beer's law equation to solve for

ε: ε = A/bc.
Since the path length, b, is the same for all the solutions, we can use any of the standard solutions to calculate ε. Let's use the first standard solution:

ε = 0.500 / (10.0 mL / 1000 mL/L) / (0.200 g/L / 63.55 g/mol) = 1580.95 L/mol·cm

Now that we know the molar absorptivity, we can use the Beer's law equation to determine the concentration of copper in the three unknown solutions:
(a) c = A / εb = 0.450 / (1580.95 L/mol·cm)(1 cm) = 2.85 x 10^-4 mol/L = 0.018 g/L
(b) c = A / εb = 0.300 / (1580.95 L/mol·cm)(1 cm) = 1.90 x 10^-4 mol/L = 0.012 g/L
(c) c = A / εb = 0.200 / (1580.95 L/mol·cm)(1 cm) = 1.27 x 10^-4 mol/L = 0.0081 g/L

Therefore, the respective concentrations of copper in the three solutions are 0.018 g/L, 0.012 g/L, and 0.0081 g/L.

The axes in the coordinate grid on the right represent the walls of a room. the distance from that corner of the room to the corner of the furthest bed is 11 axes. A coordinate grid has two perpendicular lines, or axes (pronounced AX-eez), labeled just like number lines. The horizontal axis is usually called the x-axis. The vertical axis is usually called the y-axis. The point where the x- and y-axis intersect is called the origin.

The coordinate plane has two axes: the horizontal and vertical axes. These two axes intersect one another at a point called the origin.

The x axis is in the plane of the screen and is positive toward the right and negative toward the left. The y axis is in the plane of the screen and is positive toward the top and negative toward the bottom. The z axis is perpendicular to the screen or keyboard, and is positive extending outward from the screen.

With this information, we can conclude that the distance from that corner of the room to the corner of the furthest bed is 11 axes.
