D) sodium chloride (NaCl) and hexane (c6h14) are most likely to form a solution when mixed.

Sodium chloride (NaCl) and hexane (C6H14) are two common substances that can form a solution when mixed. When these two substances are combined, the sodium chloride molecules interact with the hexane molecules and form a homogenous mixture.

This mixture allows for the two components to be evenly distributed throughout, creating a solution. The combination of sodium chloride and hexane is able to form a solution due to the polar nature of sodium chloride and the non-polar nature of hexane.

The polar nature of sodium chloride allows it to form strong hydrogen bonds with the non-polar hexane molecules, resulting in a homogenous mixture.

In the case of magnesium, calcium, aluminum, and potassium, potassium is the most reactive metal.

In general, reactivity of a metal increases as you move down a group or a column in the periodic table. The reactivity of a metal is related to the ease with which it loses electrons to form a positive ion, or cation. In the case of magnesium, calcium, aluminum, and potassium, potassium is the most reactive metal. It is located in the first group or column of the periodic table, and has the smallest atomic radius and the most loosely held outermost electrons. This makes it easier for potassium to lose electrons and form a positive ion, making it the most reactive of the four metals mentioned. Aluminum is the next most reactive, followed by calcium and magnesium. Magnesium is the least reactive of the four metals mentioned.

Sodium (Na) and chlorine (Cl) are two highly reactive elements that, when chemically bonded, form the compound sodium chloride (NaCl), more commonly known as table salt.

What is surprising about the properties of these elements when they chemically bond to form this compound is that the resulting compound is a very stable and highly crystalline solid that is not reactive or explosive like the individual elements.

Sodium, when exposed to air or moisture, reacts vigorously and can ignite or explode. Chlorine, being a halogen, is a highly reactive gas and can be toxic to living organisms. However, when they bond together, they form a stable compound that is safe to handle and consume.

Therefore, Another surprising property of this compound is that it is an ionic compound, meaning it is composed of ions with a positive charge (Na+) and negative charge (Cl-). This type of chemical bond is formed by the transfer of electrons from one atom to another, which makes it an ionic bond, different from covalent bond that is formed by the sharing of electrons.

The percent by mass of the solution of H2O2 is 1.6547%, when hydrogen peroxide decomposes into water and oxygen.

How to calculate percent by mass of the solution?

To find the percent by mass of a solution of hydrogen peroxide (H2O2) prepared from 1.423 g of H2O2 that is titrated with 40.22 mL of 0.01143 M KMnO4(aq), you will need to determine the mass of H2O2 that is actually present in the solution.

The balanced equation for the reaction is:

2KMnO4(aq) + 3H2O2(aq) + 8H+(aq) --> 2MnO2(s) + 5O2(g) + 8H2O(l)

From the equation, we know that for every 2 moles of KMnO4(aq), 3 moles of H2O2(aq) are consumed. Therefore, the number of moles of H2O2 that are actually present in the solution can be determined by multiplying the moles of KMnO4 consumed by 3/2.

The moles of KMnO4 consumed can be determined by multiplying the volume of KMnO4 used by its concentration in mol/L.

So the moles of KMnO4 = 40.22 mL x 0.01143 mol/L = 0.459 mol

The moles of H2O2 present = (3/2) x 0.459 mol = 0.6885 mol

The mass of H2O2 present = 0.6885 mol x 34.02 g/mol = 23.55 g

Therefore, the percent by mass of the solution of H2O2 is (23.55 g / 1.423 g) x 100 = 1.6547 %

the reaction's 2N2O5→2N2O4+O2  frequency factor at 303 K is A = 9.15 x 10^-4 s^-1 *

The specific rate constant (k) of a first-order reaction is given by the equation:

k = A*e^(-Ea/RT)

Where A is the frequency factor, Ea is the activation energy, R is the gas constant and T is the temperature in Kelvin.

Substituting for A:

A = k*e^(Ea/RT)

We know that the specific rate constant at 303 K is 9.15 x 10^-4 s^-1, and we can assume that the activation energy (Ea) and gas constant (R) are constant.

T = 303 K

Plugging in the known values we get

A = 9.15 x 10^-4 s^-1 * e^(Ea/R*303)

The frequency factor, A, is a measure of the number of collisions of reactant molecules per unit of time that have sufficient energy to overcome the activation energy barrier and form products. The value of A can be used to compare the relative rates of different reactions. The fact that the specific rate constant at 293 K is 2.35 x 10^-4 s^-1 and at 303 K is 9.15 x 10^-4 s^-1, indicates that the reaction rate increases with increasing temperature. This is consistent with the expected behavior of a first-order reaction, as an increase in temperature will increase the kinetic energy of the reactant molecules, making them more likely to collide with each other and form products.

The pH of a solution made by dissolving 13.7 g of hydrochloric acid (HCl) in 643 ml of water can be calculated using the following steps:

1. Calculate the molarity of the solution. This is done by dividing the amount of HCl (13.7 g) by the molar mass of HCl (36.46 g/mol), which gives us 0.376 mol of HCl. Then, divide this number by the volume of the solution (643 ml), which gives us a molarity of 0.00587 mol/L.

2. Calculate the pH of the solution. This is done by using the expression pH = -log[H+], where [H+] is the concentration of hydrogen ions in the solution. Taking the negative logarithm of 0.00587 mol/L gives us a pH of 2.23.
