Why is there an octet rule in writing Lewis structures?
Answers
Answer:
Before we can sketch the Lewis structures of molecules, we must first understand the octet rule. The octet rule asserts that when atoms combine to create compounds, electrons are gained, lost, or shared among them, resulting in a stable electron configuration defined by eight valence electrons as a result. These rules are used in conjunction with the main-group components of the second period.

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.

Answers
Explanation:
no sé de qué me estás hablando
This is a precipitation reaction and 1.38 g of the precipitate will be formed is the statement is correct. Hence, option C is correct.
What is a precipitation reaction?A precipitation reaction is when two or more dissolved chemicals combine to form one solid products. The exchange of ions between ionic compounds in aqueous solutions is a common component of these reactions, which are also occasionally referred to as double displacement, double replacement, or metathesis reactions.
in response to precipitation a process that converts soluble salts into solids that are insoluble in water. a neutralizing response an interaction between an acid and a base that results in the production of salt, water, and an ionic molecule.
Precipitate refers to a solid that forms from a solution. The blending of two transparent solutions is a common example: NaCl in combination with silver nitrate The answer is. The soli cannot be dissolved in water.
Thus, option C is correct.

Hg? (R=0.082 L atm/ mol K, 1.00 atm = 760 mm Hg
(4 points)
Answers
Answer:
-106°C
Explanation:
1558 mmHg / 1 × 1 atm / 760. mmHg = 2.05 atm
PV = nRT
2.05 atm (10.0 L) = 1.50 mol (0.082 atmL/molK) T
20.5 atmL = (0.123 atmL/K) T
K/0.123 atm L × 20.5 atmL = (0.123 atmL/K) T × K/0.123 atmL
166.666 K = T
167 K = T (sig figs)
K = °C + 273
167 - 273 = °C - 273
-106 = °C

Answers
Water has the strongest intermolecular forces followed by ethanol and diethyl ether has the least intermolecular forces.
From the table, we can see the vapor pressures of water, ethanol and diethyl ether. The boiling point of water is 100°C, the boiling point of ethanol is 80°C while the boiling point of diethyl ether is 40°C.
We can see that the vapor pressures and approximate normal boiling points of the substances varies with the nature of intermolecular bond forces in the molecule.
Water has highest boiling point and the lowest vapor pressure followed by ethanol. Diethyl ether has the highest vapor pressure and lowest boiling point from the data in the table.

Airflow through a long 0.2m square air conditioning duct maintained the outer duct surface temperature at 10degree.if the horizontal duct is uninsulated and exposed to air at 35degree in the crawl space beneath at home.
What is the heat gain per unit length of the duct.
Answers
Answer:
125°C/m
Explanation:
The difference in temperature will be:
35 - 10 = 25
The outer duct surface is heated 25°C by the air from 10°C to 35°C;
This heat gain is simply divided by 0.2m to get heat gain per unit length:
25/0.2 = 125
125°C/m
If you're American, this will be °F I believe, so the answer will be:

Describe how you could adjust the settings of the simulation to increase the number of red (H3O+) and blue (A-) particles in the solution of equilibrium. In three to four sentences, justify your answer and explain how and why this would change the pH of the solution.
Answers
The addition of more acid or base will increase the number of H3O+ and A- particles thereby decreasing and increasing the pH of the solution respectively.
What is an acid-base titration?An acid-base titration is one in which an acid is added to a given volume of base in order to neutralize it.
When more of acid is added to a solution of a base than is required to neutralize it, the solution becomes acidic.
Similarly, when more base is use to neutralize an acid than is required, the solution becomes alkaline.
In the given simulation, (H3O+) is the acid while (A-) is the base.
By adding increasing the quantity of acid added, the number of H3O+ particles will increase. This will reduce the pH of the solution.
Also, the adding more base to the solution, the number of A- particles in the solution will increase. This will increase the pH of the solution.
Therefore, addition of more acid or base will increase the number of H3O+ and A- particles thereby decreasing and increasing the pH of the solution respectively.
