Explanation:

The atomic number is equal to the number of protons of an element;

The number of protons is equal to the number of electrons if the atom is neutral (so the number of electrons is equal to the atomic number if the atom is neutral);

The number of neutrons we can calculate using the following equation:

A = p + n

Where: A is the mass number; p is the number of protons and n is the number of neutrons.

Answer: So we have y = (1/4)x - 1

Hello,

We'll assume a straight line, which takes the form y = mx + b, where x is the slope and b is the y intercept (the value of y when x = 0).  We can calculate m, the slope, by recognizing that slope is the rate of change of y as x is increased.  The increase in y (the "rise") divided by the increase in x (the "run") between those two points will give us the "rise/run", which is the slope, m.

Change in x:  (8 - (-4)) = 12 (the run)    Change in y:  (1 - (-2)) = 3 (the rise).  The rise/run is 3/12, or 1/4.  The slope is 1/4.

y = (1/4)x + b

We can calculate b by using one of the points provided (I'll choose (8,1)) and solve the equation for b:

1 = (1/4)*8 + b

b = -1

So we have y = (1/4)x - 1

Explanation:

The molar concentration of a 12% sodium chloride solution is approximately 2.05 M.

To determine the molar concentration of a 12% sodium chloride solution, we need to convert the given percentage concentration into molarity.

First, we need to understand that the percentage concentration refers to the mass of the solute (sodium chloride) relative to the total mass of the solution.

In this case, a 12% sodium chloride solution means that there are 12 grams of sodium chloride in 100 grams of the solution.

To convert this into molar concentration, we need to consider the molar mass of sodium chloride, which is 58.5 g/mol.

We can start by calculating the number of moles of sodium chloride in 12 grams:

Moles of sodium chloride = mass of sodium chloride / molar mass of sodium chloride

Moles of sodium chloride = 12 g / 58.5 g/mol = 0.205 moles

Next, we calculate the volume of the solution in liters using the density of the solution. Since the density is not provided, we assume a density of 1 g/mL for simplicity:

Volume of solution = mass of solution / density

Volume of solution = 100 g / 1 g/mL = 100 mL = 0.1 L

Finally, we calculate the molar concentration (Molarity) by dividing the number of moles by the volume in liters:

Molar concentration = moles of solute / volume of solution

Molar concentration = 0.205 moles / 0.1 L = 2.05 M

Therefore, the molar concentration of a 12% sodium chloride solution is approximately 2.05 M.

Sublimation is a physical process in which a substance transitions directly from its solid phase to its gaseous phase without passing through the intermediate liquid phase. In sublimation, the solid substance is heated, and the resulting gas molecules escape from the solid lattice structure without the need for melting.

One common example of sublimation is the process of dry ice. Dry ice is solid carbon dioxide (CO2) that sublimes at a temperature of -78.5 degrees Celsius (-109.3 degrees Fahrenheit). When dry ice is exposed to room temperature, it transitions directly from a solid to a gas, producing a fog-like effect.

Since 267.86 g is less than the 300 g of water we have, we can dissolve 150 g of potassium chloride in 300 g of water at a temperature of 70°C.

The solubility of potassium chloride in water varies with temperature. To determine the temperature required to dissolve 150 g of potassium chloride in 300 g of water, we need to consult a solubility chart or table.

At 20°C, the solubility of potassium chloride in water is approximately 34 g/100 g of water. This means that 100 g of water at 20°C can dissolve 34 g of potassium chloride. To dissolve 150 g of potassium chloride, we would need:

150 g / 34 g/100 g = 441.18 g of water

Since we only have 300 g of water, we need to increase the temperature to dissolve all of the potassium chloride. At 70°C, the solubility of potassium chloride in water is approximately 56 g/100 g of water. This means that 100 g of water at 70°C can dissolve 56 g of potassium chloride. To dissolve 150 g of potassium chloride, we would need:

150 g / 56 g/100 g = 267.86 g of water

Answer:

Explanation:

Most molecular compounds that have a mass similar to water are gases at room temperature. Because of the strong hydrogen bonds, water molecules are able to stay condensed in the liquid state, but, because of the hydrogen bonds, as water molecules come together they stick to one another for a small, but significant amount of time. Molecular water, therefore, is a liquid at room temperature

Answer:

D.

Explanation:

    This is not exactly a answer you can use but this is some information that you can use to find out the answer.

    You can usually confirm the charge associate degree particle unremarkably has by the element's position on the periodic table: The alkali metals (the IA elements) lose one negatron to create a ion with a 1+ charge. The alkaline-earth metal metals (IIA elements) lose 2 electrons to create a 2+ ion.

    Nonmetals type negative ions (anions). A range 7|chemical element|element|gas} atom should gain 3 electrons to possess an equivalent number of electrons as AN atom of the subsequent gas, neon. Thus, a gas atom can type AN ion with 3 additional electrons than protons and a charge of 3−.

The azide ion, Nsubscript3 superscript1-, is a symmetrical ion

Five valence electrons make up nitrogen.

The ion has a total of 16 valence electrons (5 * 3 + 1), making it symmetrical.

We will use all 16 of the valence electrons if we give three pairs of electrons to the two terminal N atoms to complete their octets. However, there are only 4 shared valence electrons on the core nitrogen atom.

1. N atoms can have two double bonds placed between them.

To determine the change in volume (V) given the changes in pressure (P) and temperature (T), we need to consider the relationship described by the ideal gas law:

\(\displaystyle PV = nRT\)

Where:

To analyze the effect of changing P and T on V, we'll assume that the number of moles (n) and the ideal gas constant (R) remain constant.

If P increases by a factor of 5, we can express the new pressure as:

\(\displaystyle P_{\text{new}} = 5P\)

If T decreases by a factor of 3, we can express the new temperature as:

\(\displaystyle T_{\text{new}} = \frac{1}{3}T\)

Now, let's consider the relationship between the initial and final volumes (V and V_new):

\(\displaystyle PV = nRT\)

\(\displaystyle V = \frac{nRT}{P}\)

\(\displaystyle P_{\text{new}}V_{\text{new}} = nRT_{\text{new}}\)

\(\displaystyle V_{\text{new}} = \frac{nRT_{\text{new}}}{P_{\text{new}}}\)

Substituting the expressions for P_new and T_new, we have:

\(\displaystyle V_{\text{new}} = \frac{nR\left(\frac{1}{3}T\right)}{5P}\)

Simplifying the expression:

\(\displaystyle V_{\text{new}} = \frac{1}{15}\left(\frac{nRT}{P}\right)\)

Comparing this with the initial volume (V), we can see that:

\(\displaystyle V_{\text{new}} = \frac{1}{15}V\)

Therefore, the change in volume (V) is such that it decreases by a factor of 15.

The correct option is E. V decreases by a factor of 15.
