Given that a single-displacement reaction occurred between two (2) reactants which were placed into a flask, the potential identities of A, B, and X are: D. A = Mg, B = O, X = Cl.
A single-displacement reaction is also referred to as a single-replacement reaction and it can be defined as a type of chemical reaction wherein a single (one) chemical element of the reacting chemical compound is displaced (replaced) by a similar chemical element.
This ultimately implies that, a single-displacement reaction typically involves a single element displacing another chemical element within a chemical compound.
Note: A potential identity reveals the chemical symbol or name of a chemical element in a particular chemical reaction.
Given the following general reaction of scheme of:
[tex]2AB+2X_2\rightarrow 2AX_2+B_2[/tex]
We would proceed to replace the variables with chemical elements as follows:
[tex]2MgO+2Cl_2\rightarrow 2MgCl_2+O_2[/tex]
Therefore, the potential identities of A, B, and X are:
[tex]A = Mg\\\\B = O\\\\X = Cl[/tex]

How do weak intermolecular bond strengths affect the melting and boiling point of a substance? (Picture is of answers I can choose from)
Answers
This is because weak intermolecular forces need less energy for the forces to break compared to strong intermolecular forces. Less energy required means lower temperatures - low melting and boiling points
For a weak intermolecular bond, both the melting point and boiling point are lower.
A lesser energy is required to break bond of weak intermolecular forces while a greater energy is required to break bond of strong intermolecular forces.
E ∝ T
where;
E is the energy required to break the bondT is the temperatureA lesser energy means a lower temperature and a lower temperature will result in lower boiling point and melting point.
Thus, we can conclude that for a weak intermolecular bond, both the melting point and boiling point are lower.

Relate microscopic bonding properties to solid state properties
Answers
There are many factors that we can take into account when attempting to relate microscopic bonding properties to solid-state properties, for example, the rigid and immobile nature of solid states and their molecular bonds.
Solid-state properties are simply put, the properties we can observe and measure when studying an element in solid form. These solids have specific characteristics such as:
Structural rigidityThey do not change shapeDo not change the volume they occupyand so on, which although not initially obvious, are caused by the microscopic molecular bonds of their atoms.
The microscopic properties of solids are very similar to that of the solid-state properties. The atoms of a solid are very close together and strongly bonded to one another, because of this the atoms form a very rigid structure that resists changes to their shape or volume, much like the macroscopic properties of the solid. This serves to show how these properties may cause the solid-state effects we can observe normally.

If acid comes in contact with your skin, because having an excessive amount of base can also be harmful. Acid is weakened and rendered ineffective by water.
What is acid?A chemical species known as an acid absorbs electrons and/or provides protons or hydrogen ions. When a hydrogen atom is bound to an acid, it can release (dissociate) and produce a cation as well as an anion in water. A substance's acidity and solution pH increase according to the amount of hydrogen ions it produces.
There are various definitions for acids. When someone uses the term "an acid," they typically mean an Arrhenius or Brnsted-Lowry acid. Often, a Lewis acid being referred to as a "Lewis acid." If acid comes in contact with your skin, because having an excessive amount of base can also be harmful. Acid is weakened and rendered ineffective by water.

An ideal solution consisting of 79 wt% benzene (C6H6) and 21 wt% toluene (C7H8) was heated in a closed vessel to 50 ºC. What is the mole fraction of benzene in the vapour phase when equilibrium was reached at 50 ºC? Round your answer to two significant figures.
Data: Vapour pressure of benzene at 50 ºC = 271 mmHg
Vapour pressure of toluene at 50 ºC = 91.5 mmHg
Answers
In this case, according to the Raoult's law, we can find the mole fraction of 79 wt% benzene and 21 wt% toluene at 50 °C in the vapor phase as follows:
[tex]y_iP=x_iP_i[/tex]
However, we first have to calculate the mole fractions in the solution as follows (b stands for benzene and t for toluene):
[tex]\\x_b=0.79\frac{g\ benzene}{g\ solution} *\frac{(78.11*x_b+92.14*x_t)}{1mol\ solution} *\frac{1mol\ toluene}{78.11g\ toluene} \\\\x_b=0.79\frac{g\ benzene}{g\ solution} *\frac{78.11*x_b+92.14*(1-x_b)}{1mol\ solution} *\frac{1mol\ toluene}{78.11g\ toluene}\\\\x_b=0.79*(x_b+1.18*(1-x_b))\\\\x_b=0.79x_b+0.932-0.932x_b\\\\x_b=\frac{0.932}{1+0.932-0.79} =0.816\\\\x_t=1-x_b=1-0.816=0.184[/tex]
Next, we calculate the total pressure as follows, according to the Dalton's law:
[tex]P=x_bP_b+x_tP_t=0.816*271mmHg+0.184*91.5mmHg=237.972mmHg[/tex]
Finally, the mole fractions of the vapor phase turn out:
[tex]y_b=\frac{0.816*271mmHg}{237.972mmHg}=0.929\\\\y_t=1- 0.929=0.071[/tex]

A containing vessel holds a gaseous mixture of nitrogen and butane. Thepressure in the vessel at 126.9 Cis 3.0 atm. At 0 C, the butane completelycondenses and the pressure drops to 1.0 atm. Calculate the mole fraction of nitrogenin the original gaseous mixture.
Answers
A vessel that contains a mixture of nitrogen and butane has a pressure of 3.0 atm at 126.9 °C and a pressure of 1.0 atm at 0 °C. The mole fraction of nitrogen in the mixture is 0.33.
A vessel contains a gaseous mixture of nitrogen and butane. At 126.9 °C (400.1 K) the pressure is due to the mixture is 3.0 atm.
We can calculate the total number of moles using the ideal gas equation.
[tex]P \times V = n \times R \times T\\\\n = \frac{P \times V}{R \times T} = \frac{3.0 atm \times V}{0.082 atm.L/mol.K \times 400.1 K} = 0.091 mol/L \times V[/tex]
At 0 °C (273.15 K), the pressure due to the gaseous nitrogen is 1.0 atm.
We can calculate the moles of nitrogen using the ideal gas equation.
[tex]P \times V = n \times R \times T\\\\n = \frac{P \times V}{R \times T} = \frac{1.0 atm \times V}{0.082 atm.L/mol.K \times 400.1 K} = 0.030 mol/L \times V[/tex]
The mole fraction of nitrogen in the mixture is:
[tex]X(N_2) = \frac{0.030 mol/L \times V}{0.091 mol/L \times V} = 0.33[/tex]
