Mole fraction of nh3 in the solution is 11.33%.
What is mole?
The International System of Units uses the mole (symbol: mol) as the unit of substance amount (SI). How so many elementary entities of a particular substance are present in an object or sample is determined by the quantity of that substance. There are precisely 6.02214076×10^23 elementary entities in a mole.
NH3(g) + H2O(l) = NH4OH (aq)
The molar mass of NH3 is 17.031 g/mol.
The NH3:NH4OH mole ratio is 1: 1.
Mol of NH3 = 15 g/(17.031 g/mol) = 0.88 mol, which produces (1/1) x 0.88 mol of NH4OH = 0.88 mol of NH4OH/250 g of water.
The mass of the solution is calculated as 15g + 250 g = 265 g.
Given that the density of NH4OH is 0.974 g/mL, the resulting solution contains 0.88 mol of NH4OH/265 g: 0.974 g/mL or 0.88 mol/272.0739mL.
Then, mol of NH4OH in 100mL solution = (100mL/272.0739mL) x 0.88 mol = 0.3234 mol of NH4OH/100mL solution...
……. [A]
The molar mass of NH4OH is 35.04 g/mol.
As a result, the mass of NH4OH = 0.3234 mol x 35.04 g/mol = 11.33 g of NH4OH/100mL or 11.33% (m/v).
As stated in [A], one mol of NH4OH equals 0.3234mol/100mL solution or (1000mL/100mL) x 0.3234 mol equals 3.234 mol NH4OH/L or 3.234 M.
Because NH4OH is a monoprotic base, molarity equals normality, so the resulting solution's normality = 3.234 N rounded up to 3.23 N.

what is the total pressure of a gaseous mixture that contains three gases with partial pressures of 0.845 atm, 120 torr and 210 mm hg?
The total pressure of a gaseous mixture that contains three gases with partial pressures is 972 torr.
When more than one gas is present in a container, each gas exerts pressure, which is known as partial pressure. Its partial pressure refers to the pressure of any gas inside the container.
According to Dalton's Law, also known as the Law of Partial Pressures, the combined pressure of a mixture of gases is equal to the sum of their individual partial pressures.
1 - 0.845 atm - 0.854 atm x 760 Torr/atm = 642 torr
2 - 120 torr

A cycle consists of a carefully balanced set of molecules. In order for the cycle to continue, this balance must be maintained. How many turns of the calvin cycle must occur before one molecule of g3p can leave?.
The Calvin cycle must occur before the molecule exits g3p is 3.
Three Calvin cycles are required to make the G3P molecule. This allows the G3P molecule to break out of the cycle and continue making glucose. All three requirements are required:
Chlorophyll pigments, chloroplast "theater" and enzyme catalysis. In the first stage, it converts light energy into chemical energy, which until then is stored in ATP and NADPH molecules.
In the second step of the Calvin Cycle, the carbon-fixed 3-PGA molecule is converted to the monosaccharide molecule glyceraldehyde-3-phosphate. This stage uses energy from ATP and NADPH produced in the light-dependent reactions of photosynthesis. The Calvin cycle harnesses the chemical energy of ATP and reduces the power of NADPH from a light-dependent reaction to produce tricarbonate.

Explanation:
1.2 g/mL at 25 °C
The primary component of gastric acid, which is created naturally in the human stomach to aid in food digestion, is hydrochloric acid, which is the aqueous solution of hydrogen chloride gas. For a number of industrial and commercial uses, hydrochloric acid is manufactured synthetically.
In the food, textile, metal, and rubber sectors, hydrogen chloride (HCl) is frequently employed as a bleaching agent to neutralize alkaline substances. When discharged into the soil, it is neutralized, and when it comes into contact with water, it hydrolyzes quickly.
The gases released by volcanoes contain hydrochloric acid. Additionally, the majority of mammals' digestive tracts include hydrochloric acid.
When hydrogen chloride is present in the air in high concentrations, breathing can be dangerously difficult and even deadly. Chemical burns from hydrochloric acid can be extremely painful if they come into contact with skin or other tissues. Ingestion of hydrochloric acid can result in blindness.

Under what conditions of temperature and pressure would you expect gases to obey the ideal-gas equation?.
At high temperature and low pressure conditions of temperature and pressure expect gases to obey the ideal-gas equation.
What is ideal gas equation?
Ideal gas equation is given as
[tex]PV=nRT[/tex]
In this equation, P stands for the ideal gas's pressure, V for the ideal gas' volume, n for the total amount of the ideal gas expressed in moles, R for the universal gas constant, and T for temperature.
Explanation:
As opposed to real gases, which do not adhere to the Gas Laws at all temperatures and pressures, ideal gases do.
Real gases only abide with the Gas Laws at very low pressures and high temperatures. Because of the large amount of free space between the gas molecules in these circumstances, the actual volume may be very small.

5. NAD⁺ is the compound that functions as the electron acceptor in glycolysis.
6. the reduced form of the electron acceptor in glycolysis is NADH
A substance is said to be oxidized when it loses electrons, loses hydrogen, or receives oxygen.
However, the opposite happens with reduction. In other words, when a substance gains electrons, gains hydrogen, or loses oxygen, it is said to be reduced.
A substance that itself is reduced to oxidize another substance is called an oxidizing agent. Redox reactions occur simultaneously. That is, when one substance is oxidized, only another substance is reduced.
During glycolysis, the six-carbon compound glucose (C6H12O6) loses electrons and is finally converted to a three-carbon compound known as pyruvate (CH3COCOOH). In this process, an oxidant called NAD+ receives electrons and is itself reduced to NADH.
The chemical formula for glucose is C6H12O6, while the chemical formula for pyruvate is CH3COCOOH. Looking at their chemical formulas, it is easy to see that glucose has lost hydrogen compared to pyruvate. That means that glucose has been oxidized. Glucose has 12 hydrogens for 6 carbons, but pyruvate has only 4 hydrogens for 3 carbons. This means that glucose was oxidized in the process because the molecule produced, pyruvate, has relatively few hydrogens.

This will probably be the case for every issue you run into in this course involving freezing point depression as well as boiling point elevation, but it's a good idea to watch out for ions. It is important to note that both nonvolatile and volatile solutions can be modelled by these equations. This implies that the vapour pressure has no bearing on the change in temperature for the purpose of determining the freezing point depression as well as boiling point elevation. Additionally, keep in mind that a pure solvent is indeed a solution that hasn't had anything else dissolved or added to it. We'll contrast the solvent's original properties with those it acquires after being mixed with a solution.
ΔTf= Kf · b · i
ΔTf =freezing-point depression
Kf =cryoscopic constant
b =molality
i =van 't Hoff factor

True or false? several food webs can be combined to make a food chain.
Answer:
the answer is true
Explanation:
the reason why is because if you look at it a chemical in a repeating form os a compound so that means it is the same properties for food.
Answer:
True
Explanation:
Many different species eat grass, and rabbits can eat other plants besides grass. Foxes, in turn, can eat many types of animals and plants. Each of these living things can be a part of multiple food chains.
