Answer:
447.64 grams
Explanation:
To find the mass when given moles, it is a pretty simple process.
I start by finding the molar mass of chloric acid, which comes out to 84.46 grams/mol. To find the MM (molar mass), you just take the mass of each element in the molecule from the periodic table and add them all together.
After this, you set up the equation by taking the moles given and multiplying it by the molar mass. This gives you the new value in grams (since we cancelled out the moles). I have attached my work below.
I hope this helps! :^)
The mass of 5.3 moles chloric acid has been 447.85 g.
The mass of 1 mole of a compound has been equivalent to the molar mass of the compound. The molar mass of a compound has been the sum of the constituent atoms in a formula unit.
The molar mass (mwt) of chloric acid has been given as:
[tex]mwt=m_H\;+\;m_C_l\;+\;(m_O\;\times\;3)[/tex]
By substituting the values for the mass of constituent atoms, the molar mass has been given as:
[tex]mwt=1\;+\;35.5\;+\;16\;\times\;3\\mwt=36.5\;+\;48\\mwt=84.5[/tex]
The molar mass of chloric acid has been 84.5 g/mol.
The mass of 1 mole of chloric acid has been 84.5 g/mol. The mass of 5.3 moles chloric acid has been:
[tex]\rm 1\;mol=84.5\;g\\5.3\;mol=5.3\;\times\;84.5\;g\\5.3\;mol=447.85\;g[/tex]
The mass of 5.3 moles chloric acid has been 447.85 g.

Answer:
Glycerin
Explanation:
The stronger the intermolecular forces of attraction the more energy is required to break those forces, if you need more energy to break these forces it means that these certain elements would have a higher boiling point. Which is why the answer is Glycerin, the highest boiling point of an element means that it has the strongest forces, which in this case is electrostatic forces.

Answers
Answer: -13% to 3 sig figs
Explanation:
A piece of potato had an original mass of 3.2g and after being left in a sugar solution for 24 hours it then had a mass of 2.8g. Calculate the percentage mass decrease of the potato.
the change in mass is 2.8 -3.2 = -0.4 gm
the % change fro the origial piece is ( -0.4/3.2) X 100 = -12.5%

The table compares vapor pressure values for water ethanol and diethyl ether Add six temperatures determine the approximate normal boiling point for each substance what do the data suggest about the relative strength of attraction between particles in each substance
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.

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.

a peanut butter and jelly sandwich contains 9.00 g of fat, 6.00 g of protein, and 25.0 g of carbohydrate. How many calories does this sandwich provide?
Answers
Answer:
205 calories.
Explanation:
According to the USDA, "Carbohydrates provide 4 calories per gram, protein provides 4 calories per gram, and fat provides 9 calories per gram." 9 grams of fat at 9 calories per equals 81 calories + 6 grams of protein at 4 calories per gram which equals 24 calories + 25 grams of carbohydrate at 4 calories per gram which is equal to 100 calories.
Total that all up and you get 81 cal + 24 cal + 100 cal=205 calories.
I don't know what kind of course this is for, but if they are incredibly picky, what we refer to as "calories" are actually kilocalories, which are equal to one thousand "real" calories each. However, I'm very confident that the correct answer is 205 calories.
The sandwich will provide 205 calories.
What is calories?A calorie is an energy unit. It's the quantity of heat needed to increase the temperature of one gramme of water by [tex]1^{0} C[/tex] at one atmosphere of pressure.
Its is given that, Fat = 9 g, protein = 6 g, carbohydrate = 25 g.
It is known that, fat contains 9 calories / gram , carbohydrate contains 4 calories / gram and protein contains 4 calories / gram.
Now, adding all terms.
Total calories = (9×9) +(6×4) +(25×4)
= 205 calories.
Therefore, the sandwich will provide a total of 205 calories.

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:

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.

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.
