The electron geometry (eg) of CO2-3 is trigonal planar. This is because the carbon atom has three other atoms bonded to it (two oxygen atoms and one negative charge), and the bonds of these three atoms form a triangle.

Trigonal planar is a molecular geometry that is characterized by three atoms or groups of atoms that are all in the same plane and all bond angles are equal to 120 degrees.

The molecular geometry (mg) of CO2-3 is linear. This is because the three atoms are arranged in a straight line, with the negative charge located in the middle. The linear shape of the molecule is due to the repulsion of the negative charge between the two oxygen atoms, pushing them away from each other.

For filtering particles from a 180°F gas stream containing ammonia, a suitable fabric would be PTFE (Polytetrafluoroethylene). For the 250°F gas stream containing SO₂, a suitable fabric would be P84 (Polyimide).

When dealing with a 180°F gas stream containing ammonia, PTFE fabric is a good choice due to its excellent chemical resistance and high-temperature stability. PTFE is known for its nonstick properties and resistance to a wide range of chemicals, including ammonia. It can withstand high temperatures and is capable of filtering out particles effectively.

In the case of a 250°F gas stream containing SO₂, P84 fabric is a suitable option. P84, a polyimide-based fabric, exhibits excellent resistance to acids, alkalis, and organic solvents, making it suitable for environments containing SO₂. It has good thermal stability, allowing it to withstand the high temperatures of the gas stream. P84 fabric also has a high filtration efficiency and can effectively capture fine particles.

Both PTFE and P84 fabrics are commonly used in industrial filtration applications due to their chemical resistance, high-temperature stability, and efficient particle filtration capabilities. However, it's important to consider specific operating conditions, such as gas composition, temperature, and other factors, to ensure the chosen fabric is compatible and optimized for the intended application.

The reaction would tend to proceed in the reverse direction, resulting in an increase in the concentrations of \(SO_2\) and \(O_2\), and a decrease in the concentration of \(SO_3\), until equilibrium is reached.

The reaction between sulfur dioxide (\(SO_2\)) and oxygen (\(O_2\)) to form sulfur trioxide (\(SO_3\)) is an exothermic reaction. According to Le Chatelier's principle, at high temperatures the equilibrium position of an exothermic reaction shifts towards the reactants side. Therefore, the reaction would tend to proceed in the reverse direction.

The balanced chemical equation for the reaction is:

\(2SO_2(g) + O_2(g) = 2SO_3(g)\)

The initial moles of the reactants are:

n(\(SO_2\)) = 0.200 mol

n(\(O_2\)) = 0.300 mol

n(\(SO_3\)) = 0.500 mol

To determine the reaction quotient Q, we divide the product of the concentrations of the products (raised to their stoichiometric coefficients) by the product of the concentrations of the reactants (raised to their stoichiometric coefficients):

\(Q = [SO_3]^2 / ([SO_2]^2 * [O_2])\)

Substituting the initial concentrations into the expression for Q:

Q = (0.500 mol/dm^3)^2 / ((0.200 mol/dm^3)^2 x (0.300 mol/dm^3))

Q = 20.83

The reaction quotient Q is greater than the equilibrium constant Kc at 1000K for this reaction, which is around 1. Hence, the reaction is not at equilibrium and will shift in the reverse direction to reduce Q. This means that some of the sulfur trioxide will react to produce sulfur dioxide and oxygen.

The molecular formula of eugenol is C10H12O2.  

To determine the molecular formula, we need to know the molar mass of eugenol. The molar mass of eugenol can be calculated using the given mass of eugenol (157.0 mg) and the volume of the solution (9.562 mm).
First, convert the mass of eugenol to grams by dividing by 1000:
157.0 mg = 0.157 g
Next, calculate the molarity of the solution using the volume and mass:
Molarity (M) = moles of solute / volume of solution (L)
Convert the volume from milliliters to liters by dividing by 1000:
9.562 mm = 0.009562 L
Now we can calculate the molarity:
Molarity = 0.157 g / 0.009562 L = 16.387 M

Since the molarity is given in moles per liter, we can divide the molar mass by the molarity to find the number of moles of eugenol:
Number of moles = molar mass / molarity
Number of moles = 0.157 g / 16.387 M = 0.00957 moles
From the molecular formula of eugenol, we know that it has 10 carbon atoms, 12 hydrogen atoms, and 2 oxygen atoms. The molar mass of eugenol is 164.2 g/mol. By dividing the molar mass by the number of moles, we can find the molecular formula:
164.2 g/mol / 0.00957 moles = 17162

Sublimation is the process of transformation directly from the solid phase to the gaseous phase, without passing through an intermediate liquid phase. ... This is because the pressure of their triple point is very high and it is difficult to obtain them as liquids.

In this diagram, When the volume is constant and Pi is the initial pressure, the work done by the gas will be zero because the area under the curve made with the axis is zero, hence work=0. Work also equals Pdv when dv is zero.

Now since the volume is constant work done by the gas will be zero. As volume is not changing, the P-V diagram will run parallel to the Y axis (along which pressure lies). If the initial pressure is p, so final pressure is 7p/10. Four macroscopic features of ideal gases are related by the ideal gas law (pressure, volume, number of moles, and temperature).

Explanation:

To solve this question we need to find as first the mass that must be added of water to make 1000mL of syrup using specific gravity. Thus, we can know the volume of water that mus be added:

1.31 is 1.31g/mL. In 1000mL = 1310g/1000mL. As the mass added of sucrose is 850g, the mass of water = Volume of water is:

1310g - 850g = 460g of water = 460mL to make 1L, To make 2L the amount of water that must be added is:

460mL * 2  =

The number of milliliters of water are used to prepare two liters of syrup is 920 mL of water.

Given that,

Based on the above information, the calculation is as follows:

1.31 is = 1.31g/mL.

Now

In 1000mL = \(1310g \div 1000mL\).

Now if the mass is added so the mass of water should be equivalent to the volume of the water.

= 1310g - 850g

= 460g of water

Now

= 460mL for 1L,

The type of metabolism yeast use to generate carbon dioxide that makes bread rise is anaerobic fermentation.

Yeast is a microorganism that undergoes fermentation in the absence of oxygen. During the fermentation process, yeast breaks down sugars, such as glucose, through a series of metabolic reactions. One of the byproducts of this process is carbon dioxide (CO2). The carbon dioxide gas gets trapped within the dough, causing it to rise and give the bread a light and fluffy texture.

Anaerobic fermentation is the specific type of fermentation that occurs in the absence of oxygen. Yeast carries out anaerobic fermentation to produce energy when oxygen is not available. This process does not require oxygen and is therefore suitable for the conditions found in bread dough.

The price of mercury used to make one manometer is $2.600X, and the price of mercury used to make 15 manometers is $39.00X, where X represents the cost of mercury per cubic inch.

To find the price of the mercury used to make one manometer, we need to know the cost of mercury per cubic inch. Once we have that information, we can calculate the cost for one manometer by multiplying the volume of mercury used (2.600 in^3) by the cost per cubic inch.

Let's assume the cost of mercury is $X per cubic inch.

Price of mercury used to make one manometer = Volume of mercury used * Cost per cubic inch

= 2.600 in^3 * $X/in^3

= $2.600X

Now, to find the price of mercury used to make 15 manometers, we can multiply the cost of one manometer by the number of manometers.

Price of mercury used to make 15 manometers = Price of one manometer * Number of manometers

= $2.600X * 15
