What produces a total of 2 ATP molecules from each glucose molecule?.

Answers

Anaerobic respiration results in the production of 2 ATP molecules from each glucose molecule

Both aerobic and anaerobic conditions are conducive to glycolysis. Pyruvate enters the citric acid cycle and goes through oxidative phosphorylation, which results in the net synthesis of 32 ATP molecules under aerobic conditions.

Pyruvate undergoes anaerobic glycolysis under anaerobic circumstances, converting to lactate. Two ATP molecules are produced during anaerobic respiration. A monosaccharide containing six carbon atoms and six oxygen atoms, glucose is a hexose sugar.

Aldehyde group is connected to the first carbon, and hydroxyl group is attached to each of the next five carbons. In the course of glycolysis, glucose eventually decomposes into pyruvate and energy, yielding a total of 2 ATP (Glucose + 2 NAD+ + 2 ADP + 2 Pi --> 2 Pyruvate + 2 NADH + 2 H⁺ + 2 ATP + 2 H₂O).

Phophorylation is made possible by the hydroxyl groups. Glucose 6-phosphate is the specific kind of glucose that is employed in glycolysis.

What is the kinetic energy of a 750 kg car moving at 50. 0 km h?.

Answers

The kinetic energy of a 750 kg car moving at 50.0 km h is  72300 joules.

The capacity of an object to perform work is called energy, and like work, energy has a unit called the joule (J). Although energy can take many various forms, kinetic energy is the one that comes to mind when we talk about it. Since it is used to describe moving objects, kinetic energy is frequently conceived of as the energy of motion.

mass of car (m)= 750 kg

speed of car (v)= 50 km/h

= 50 x 5/18

= 13.9 m/s

we know that kinetic energy= 1/2 x m x v²

= 1/2 x 750 x 13.9²

= 72300 joules

so the kinetic energy is 72300 joules.

if you use too much hot solvent when dissolving your crude compound, how will that impact the recovery of your compound and why?

Answers

If you use too much solvent, the solution may become too dilute to produce crystals. It is critical to gradually chill the flask in room temperature and finally in ice water.

Impurities will be trapped within the crystal  in a hurried crystal formation. In addition, the resultant crystals will be smaller.A solvent is a substance that dissolves a solute, resulting in a solution. A solvent is often a liquid, although it can also be solid, gas, or supercritical fluid. Water is a polar molecular solvent and the most commonly employed solvent by living ; all ions and proteins in a cell are dissolved in water within the cell.Solvents are  used in paints, paint removers, inks, and dry cleaning. Organic solvents are used in dry cleaning (for example, tetrachloroethylene); paint thinners (toluene, turpentine); nail polish removers and glue solvents (acetone, methyl acetate, ethyl acetate); spot removers (, petrol ether); detergents (citrus ); and scents.

the point at which the perpendicular bisectors intersect in a triangle

Answers

The point at which the perpendicular bisectors of the sides of a triangle intersect is called the circumcenter of the triangle.

What is a circumcenter?

The circumcenter of a triangle is the point where the perpendicular bisectors of the sides of the triangle intersect. It is the center of the circumcircle, which is the circle that passes through all three vertices of the triangle.

The circumcenter is equidistant from all three vertices of the triangle and is always inside the triangle. Additionally, it is the intersection of the medians, altitudes, angle bisectors and perpendicular bisectors of the triangle.

The circumcenter can also be found by other methods. It is the intersection of the medians, which are the line segments that connect each vertex of the triangle to the midpoint of the opposite side.

It is also the intersection of the altitudes, which are the line segments that are perpendicular to the sides of the triangle and pass through the opposite vertex. The circumcenter is also the intersection of the angle bisectors, which are the line segments that bisect the angles of the triangle and pass through the vertex of the triangle.

How many molecules are present in 10 grams?.

Answers

The number of molecules present in 10 grams of a substance depends on the molar mass of the substance.

The molar mass is the mass of one mole of a substance (6.022 x 10²³) of its molecules. To determine the number of molecules present in 10 grams, we can use the formula:

Number of moles = mass/molar mass Number of molecules

= Number of moles x Avogadro's number (6.022 x 10²³)

For example, if the substance is water, its molar mass is 18.015 grams per mole, and 10 grams of water would contain:

Number of moles = 10/18.015 = 0.5556 moles

Number of molecules = 0.5556 x 6.022 x 10²³ = 3.33 x 10²²

It's important to note that Avogadro's number, which is the number of atoms, ions, or molecules in one mole of a substance, is a physical constant and is the same for all substances. So, the number of molecules present in 10 grams of a substance can be calculated by dividing the mass of the substance by its molar mass and then multiplying it by Avogadro's number.

Answers

The heat energy needed to change the 5.25  gram sample from a temperature of 49.5 to 40.5 °C is given 10.4  J. Then, the specific heat of the metal is 0.22 J/°C g.

What is calorimetry ?

Calorimetry is an analytical  technique used to determine the heat energy absorbed or released by  a system. The calorimetric equation relating the heat energy q with the mass of the substance, m, specific heat, c and temperature difference, ΔT is given as:

q = m c ΔT.

Given that the mass of the sample of iron = 5.25 g

temperature difference   ΔT = 49.5 - 40.5 = 9 °C

specific heat c = 0.450 J/ g °C.

The heat energy absorbed by the sample is calculated as follows:

10.4 J = 5.25 g ×  c J/ g °C × 9 °C.

Then,

c = 10.4 J / (5.25 g ×9 °C )

  = 0.22 J/ g °C

Which qualities of the ocean help it to absorb heat?

Answers

The qualities of the ocean help it to absorb heat is its surface area.

The ocean temperature in each area is different, this is because each region has a different amount of light intensity. Apart from light, geographical location, wind gusts, and cloud conditions can affect the ocean surface temperature which can change. while the deep ocean tends to have a stable temperature.

Water has the property of absorbing heat more easily than air because of the hydrogen bonds between water molecules. When heat is absorbed it will cause the hydrogen bonds to break and water molecules can move freely so that the surface temperature of the water rises. The more surface area of ​​ocean, the more heat absorbed by ocean.  This causes the surface area of ​​ocean to become one of the ocean qualities that helps absorb heat.

how are q and w related during this isothermal expansion?

Answers

According to the First Law of Thermodynamics ΔU = Q + W in IUPAC convention, it follows that Q = −W for the isothermal expansion or compression of an ideal gas.

In thermodynamics, an isothermal process is one of the types of thermodynamic processes, in which the temperature (T) of a system remains constant, i.e. ΔT = 0. This, in a typical manner, occurs when a system is in direct contact with an outside thermal reservoir, and a change in this system occurs slowly enough to allow the system to be continuously and gradually adjusted to the temperature of the reservoir through heat exchange.

When the vacuum gets expanded in an isothermal expansion, it leads to the free expansion of a gas. In the case of an ideal gas, the rate of free expansion is NIL (0), that implies that the work done is 0. The value of 0 is the result regardless of whether the isothermal expansion process is irreversible or reversible. 

Some of the examples of reversible cases of isothermal process include converting ice from its solid-state to the liquid-state of water, hydrogenation and dehydrogenation in milling a chemical, etc.

Examples for an irreversible condition of an isothermal process include work that is done against the friction, , magnetic hysteresis, Joule’s heating effect, etc.

I do not care to know people who are not.When I arrived, they gave me a princely reception, which at once awakened suspicion in my mind. They fired off rifles, embraced me, made much of me, as if they expected to have great fun at my expense.I said to myself: "Look out, old ferret! They have something in store for you."[5] During the dinner the mirth was excessive, exaggerated, in fact. I thought: "Here are people who have more than their share of amusement, and apparently without reason. They must have planned some good joke. Assuredly I am to be the victim of the joke. Attention!"During the entire evening every one laughed in an exaggerated fashion. I scented a practical joke in the air, as a dog scents game. But what was it? I was watchful, restless. I did not let a word, or a meaning, or a gesture escape me. Every one seemed to me an object of suspicion, and I even looked distrustfully at the faces of the servants.The hour struck for retiring; and the whole household came to escort me to my room. Why? They called to me: "Good-night." I entered the apartment, shut the door, and remained standing, without moving a single step, holding the wax candle in my hand.I heard laughter and whispering in the corridor. Without doubt they were spying on me. I cast a glance round the walls, the furniture, the ceiling, the hangings, the floor. I saw nothing to justify suspicion. I heard persons moving about outside my door. I had no doubt they were looking through the keyhole.An idea came into my head: "My candle may suddenly go out and leave me in darkness."[10] Then I went across to the mantelpiece and lighted all the wax candles that were on it. After that I cast another glance around me without discovering anything. I advanced with short steps, carefully examining the apartment. Nothing. I inspected every article, one after the other. Still nothing. I went over to the window. The shutters, large wooden shutters, were open. I shut them with great care, and then drew the curtains, enormous velvet curtains, and placed a chair in front of them, so as to have nothing to fear from outside.Then I cautiously sat down. The armchair was solid. I did not venture to get into the bed. However, the night was advancing; and I ended by coming to the conclusion that I was foolish. If they were spying on me, as I supposed, they must, while waiting for the success of the joke they had been preparing for me, have been laughing immoderately at my terror. So I made up my mind to go to bed. But the bed was particularly suspicious-looking. I pulled at the curtains. They seemed to be secure.All the same, there was danger. I was going perhaps to receive a cold shower both from overhead, or perhaps, the moment I stretched myself out, to find myself sinking to the floor with my mattress. I searched in my memory for all the practical jokes of which I ever had experience. And I did not want to be caught. Ah! certainly not! certainly not! Then I suddenly bethought myself of a precaution which I considered insured safety. I caught hold of the side of the mattress gingerly, and very slowly drew it toward me. It came away, followed by the sheet and the rest of the bedclothes. I dragged all these objects into the very middle of the room, facing the entrance door. I made my bed over again as best I could at some distance from the suspected bedstead and the corner which had filled me with such anxiety. Then I extinguished all the candles, and, groping my way, I slipped under the bed clothes.For at least another hour I remained awake, starting at the slightest sound. Everything seemed quiet in the chateau. I fell asleep.I must have been in a deep sleep for a long time, but all of a sudden I was awakened with a start by the fall of a heavy body tumbling right on top of my own, and, at the same time, I received on my face, on my neck, and on my chest a burning liquid which made me utter a howl of pain. And a dreadful noise, as if a sideboard laden with plates and dishes had fallen down, almost deafened me.[15] I was smothering beneath the weight that was crushing me and preventing me from moving.
