The spin of the electron is represented by the spin quantum number, ms; ms = +1/2 or -1/2.

Electron in orbital type 2pz.

The primary quantum number, n=1, 2, 3, and n=2 (the second energy level), is one of the four quantum numbers that are assigned to each electron in an atom to define that electron's state.

An atomic orbital's azimuthal quantum number characterizes the form of the orbital and is used to calculate the orbital's angular momentum. When l = 1, the p subshell is defined as l = 0,1...n-1.

The orbital in which the electron is placed is indicated by the magnetic quantum number, ml. ml = -l...+l, and ml = 0 indicates the Pz orbital.

Nitrogen dioxide, NO2, an air pollutant, dissolves in rainwater to form a dilute solution of nitric acid. The equation for the reaction is 3NO2(g) + H2O(l) → 2HNO3(l) + NO(g). So, the standard entropy change for the reaction is -536.0 J/K.

To calculate ∆So for the reaction, we need to determine the standard entropy change (∆So) for each of the products and reactants, and then use them in the equation:

∆So = ΣS°(products) - ΣS°(reactants)

The standard entropy values can be found in a thermodynamics table, and for this reaction they are:

S°(NO₂(g)) = 239.9 J/K
S°(H₂O(l)) = 69.9 J/K
S°(HNO₃(l)) = 146.8 J/K
S°(NO(g)) = 240.0 J/K

Substituting these values into the equation, we get:

∆So = [2(146.8 J/K) + 240.0 J/K] - [3(239.9 J/K) + 69.9 J/K]
∆So = 293.6 J/K - 829.6 J/K
∆So = -536.0 J/K

Therefore, by calculating we can say that the standard entropy change for the reaction is -536.0 J/K.

The theoretical yield of NH3 is 10.03 g and percent yield is 10.56%

The theoretical yield is obtained from the eequation if reaction.

The equation of the reaction is given below:

moles of reactants and products:

moles of H2 = 1.77/2 = 0.885 moles

moles of N2 = 25.7/28 = 0.918 moles

moles of NH3 = 1.06/17 = 0.062

From the equation of the reaction, H2 is the limiting reactant

3 moles of H2 produces 2 moles of NH3

0.885 moles of H2 will produce 2/3 × 0.918 = 0.59 moles of NH3

Therefore:

theoretical yield = 0.59 × 17

theoreticalyield = 10.03 g of NH3

Percent yield = 1.06/10.03 × 100%

percent yield = 10.56%

Therefore, the theoretical yield is 10.03 g and percent yield is 10.56%.

The mass of AI needed to react with 72 g of HCI is 54 g.

To determine the mass of AI needed to react with 72 g of HCI, we can use the stoichiometry of the balanced chemical equation you provided:

2AI + 6HCI --> 2AICI3 + 3H

From the equation, we can see that 2 moles of AI react with 6 moles of HCI to produce 2 moles of AICI3.

This means that the mole ratio between AI and HCI is 2:6 or 1:3.

Given the molar mass of HCI is 36 g/mol, we can calculate the number of moles of HCI in 72 g of HCI by dividing 72 g by the molar mass of HCI:

Number of moles of HCI = mass of HCI / molar mass of HCI

Number of moles of HCI = 72 g / 36 g/mol

Number of moles of HCI = 2 moles

Since the mole ratio between AI and HCI is 1:3, the number of moles of AI needed to react with 2 moles of HCI is also 2 moles.

Now, we can use the molar mass of AI, which is 27 g/mol, to calculate the mass of AI needed to react with 2 moles of HCI:

Mass of AI = number of moles of AI × molar mass of AI

Mass of AI = 2 moles × 27 g/mol

Mass of AI = 54 g

The limiting component or reactant in a chemical process is the one that controls how much product is created. Because metals and compounds respond in a balanced chemical equation according to their mole ratios, a limiting reactant is necessary.

When a chemical reaction is complete, the limiting reagent—also known as the limiting reactant or limiting agent—is the component that has been completely consumed.  Since the process cannot proceed without this reagent, the quantity of product that can be produced is constrained.

Excess reagents or surplus reactants are any chemicals that are present in amounts greater than those necessary to cause a reaction with the limiting reagent (sometimes abbreviated as "xs").

Answer: Ovalbumin (Albumin)

Explanation:

The albumen (egg white) is composed of almost 60% of the protein ovalbumin. It's the main source of proteins for tissue synthesis in the embryo. It acts as a storage protein, storing ions and amino acids necessary for embryonic development.

There are four different proteins present in egg white. In which the most abundant protein is ovalbumin present in 54 %.  

Proteins are biomolecules very essential for life. Proteins are made of a number of amino acids.  Amino acids join together to form peptides and large number of peptides constitute a protein.

Essential amino acids have to be up taken from diet and non-essential will be produced inside the body.

Proteins are the major substances to build up our body. There are essential and non essential amino acids. Nails and hair are made of keratin protein. Milk contains the protein called lactine.

Similarly the protein in curd is casein. The proteins in egg white are ovalbumin, ovotransferrin, ovomucin and ovomucoid. In which ovalbumin is most abundant.

The lifting force on an airplane's wing  Increases with speed.

The lifting pressure, lifting force, or virtually lift is the sum of all of the forces on a body that forces it to transport perpendicular to the route of flow.

Drag and Thrust are all “mechanical forces.” A mechanical force is generated through the interplay between an item and a fluid (liquid or gas). Weight is a “field force.” A subject's pressure no longer has to be in physical contact with the item to have an impact on the object.

The lift equation states that carry L is identical to the carry coefficient Cl times the density r times half of the velocity V squared instances the wing region A. For given air conditions, form, and inclination of the item, we have to decide a value for Cl to determine the raise.

Taking into account the reaction stoichiometry, 15 moles of H₂SO₄ are needed to completely react with 10.0 mol of aluminum.

In first place, the balanced reaction is:

2 Al(s) + 3 H₂SO₄(aq) → Al₂(SO₄)₃(aq) + 3 H₂(g)

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:

The following rule of three can be applied: If by reaction stoichiometry 2 moles of Al react with 3 moles of H₂SO₄, 10 moles of Al react with how many moles of H₂SO₄?

moles of H₂SO₄= (10 moles of Al× 3 moles of H₂SO₄) ÷ 2 moles of Al

moles of H₂SO₄= 15 moles

113.4 gallons to deciliters is 4.293×10³dL(option D)

Both gallons and litres are used to measure volumes. Deciliter is a small scale of litres and 10 deciliters make 1 litre. To convert from gallon to deciliters, we have to convert from gallon to litres first and litres to deciliters.

3.7854 litres make 1 gallon, therefore 113.4 gallons will give 113.4× 3.7854 litres = 429.26

1 litres = 10dL

429.6 litres = 10× 429.26 dL= 4292.6 = 4.293×10³dL

Answer:

Not sure about this one, sorry

Explanation:

The value of a conservative force does not depend on the path it takes. The correct answer is no.

The value of a conservative force does not depend on the path it takes. This is because the work done by a conservative force is independent of the path taken by the object.

However, if the force is non-conservative, then the work done depends on the path taken. The value of a non-conservative force is path-dependent. This means that the amount of work done by a non-conservative force depends on the path taken by the object. Therefore, the answer to the question is No.

ii. use magnet

III. husking

iv. floatation

v. Fractional distillation

Answer:

True. The limiting reagent is the reactant that is completely consumed in a chemical reaction and limits the amount of product that can be formed. The theoretical yield is the maximum amount of product that can be obtained from the limiting reagent, assuming that the reaction goes to completion and no side reactions occur. However, in practice, it is common for side reactions to occur, which can reduce the actual yield of the product. Therefore, while the limiting reagent does control the theoretical yield of a reaction, the actual yield may vary due to the presence of side reactions or other factors that can affect the efficiency of the reaction.
