The net change in NADH, FADH2, and GTP from the passage of two acetyl-scoa molecules through the citric acid cycle will be  2 GTP, 6 NADH, and 2 FADH2.

The tricarboxylic acid (TCA) cycle, frequently known to as the Krebs cycle or the citric acid cycle, is the primary route that cells use in order to generate energy and is an essential component of aerobic respiration. The cycle converts the oxidative potential of acetyl CoA into the reductive potential of NADH.

One molecule of acetyl CoA results in the creation of three molecules of NADH, one molecule of FADH2, and one molecule of GTP. Thus, for every 2 molecules of acetyl CoA, 6 NADH, 2 FADH2, and 2 GTP molecules are produced.

The stroke volume of the subject is approximately 8000 mL or 8 liters per beat, the subject has a cardiac output of 4.5 L/min. and an R-R interval.

To calculate the stroke volume (SV) of the subject, we need to use the formula:

SV = cardiac output/heart rate

However, the heart rate is not directly provided in the given information. The R-R interval represents the time between consecutive R waves in an electrocardiogram (ECG) and can be used to calculate the heart rate (HR).

The heart rate (HR) is the reciprocal of the R-R interval:

HR = 1 / R-R interval

Given that the R-R interval is 1.3333 seconds, we can calculate the heart rate:

HR = 1 / 1.3333 sec ≈ 0.75 Hz

Now, we can use the calculated heart rate and the given cardiac output to find the stroke volume:

SV = cardiac output/heart rate

SV = 4.5 L/min / 0.75 Hz

To convert the cardiac output from liters per minute to milliliters per minute, we multiply by 1000:

SV = (4.5 L/min * 1000 mL/L) / 0.75 Hz

SV ≈ 6000 mL / 0.75 Hz

SV ≈ 8000 mL/beat

Therefore, the stroke volume of the subject is approximately 8000 mL or 8 liters per beat.

We know that the stoichiometry of a reaction can help us to be able to find the amount of the substances that have been used in a process. In this case, we have been shown the balanced reaction equation of the reaction in the image that have been attached to the question.

We can see that;

Mass of the iron III oxide = 80 tonnes or 8 * 10^7 g

Mass of iron produced =  40 tonnes of 4 * 10^7 g

Number of moles of iron III oxide reacted = 8 * 10^7 g/160 g/mol

= 5 * 10^5 moles

If 1 mole of iron III oxide produces 2 moles of iron

5 * 10^5 moles of iron III oxide produces;

5 * 10^5 moles * 2 moles/ 1 mole

Explanation:

Absorption of Infrared radiation affects a molecule in which "IR energy can cause the bonds to break between certain atoms."

Infrared (IR) radiation is a form of electromagnetic radiation that interacts with molecules by inducing vibrations in the bonds between atoms. When IR energy is absorbed by a molecule, it can cause the bonds between certain atoms to stretch, vibrate, and even break.

IR energy is typically associated with the stretching and bending vibrations of covalent bonds in a molecule. Different types of bonds, such as C-H, O-H, N-H, C=O, and C-C bonds, have characteristic vibrational frequencies in the IR region. When a molecule absorbs IR radiation, it can absorb energy that matches the vibrational frequency of these bonds, leading to changes in the bond lengths and angles.

In some cases, the absorption of IR energy can result in the breaking of bonds between certain atoms. This occurs when the absorbed energy is sufficient to overcome the bond strength and disrupt the covalent bond. Bond breaking can lead to the formation of new chemical species or the rearrangement of atoms in a molecule.

It's important to note that IR energy does not typically cause electrons to move to higher orbitals in the molecule. Electronic transitions involving higher energy orbitals usually occur in the ultraviolet (UV) or visible region of the electromagnetic spectrum, rather than in the IR region.

Hence, The correct statement is: "IR energy can cause the bonds to break between certain atoms."

This is happened because, in water there is strong intermolecular force of attraction because of H- bonding. But, in case of HCl, the force of attraction is not so strong

The state of water at room temperature is liquid while Hydrogen chloride is a gas at room temperature. In consideration of three Van der Waals forces ( Keesom,  Debye, and London) which both Water and hydrogen chloride exhibit, Water exhibits hydrogen bonding, which Hydrogen chloride doesn't.

Since water has strong hydrogen bonds, more energy is required to boil water. Water has an electronegative O, water can form hydrogen bonds with other H20 molecules. We know that the hydrogen bond is stronger than the permanent dipole interaction in hydrogen chloride.

Since more energy is required to overcome the hydrogen bond in water.

Hence, the boiling point of water is 100°C while hydrogen chloride is -115°C.

When the carbonic acid sodium bicarbonate buffer pair buffers lactic acid, the following reaction occurs:$$\text{HCO}_3^- + \text{H}^+ \leftrightarrow \text{H}_2\text{CO}_3$$The carbonic acid/bicarbonate buffer system is one of the most important in human blood. When the pH of the blood decreases (becomes more acidic), the amount of bicarbonate ions in the blood decreases, and the concentration of hydrogen ions increases.

A buffer is a solution of a weak acid and its conjugate base that prevents changes in pH when small amounts of strong acid or base are added. Buffer systems protect organisms from pH changes by regulating and neutralizing acids and bases that enter or are produced by cells.

When the carbonic acid sodium bicarbonate buffer pair buffers lactic acid, the following reaction occurs:$$\text{HCO}_3^- + \text{H}^+ \leftrightarrow \text{H}_2\text{CO}_3$$The carbonic acid/bicarbonate buffer system is one of the most important in human blood. When the pH of the blood decreases (becomes more acidic), the amount of bicarbonate ions in the blood decreases, and the concentration of hydrogen ions increases. To balance the excess hydrogen ions, carbonic acid (H2CO3) is formed from carbon dioxide (CO2) and water (H2O). Carbonic acid then decomposes to form bicarbonate ions and hydrogen ions, and the pH of the blood is returned to normal. The bicarbonate ions act as a base, neutralizing the excess hydrogen ions that cause the blood to become more acidic. This is called the bicarbonate buffer system. Lactic acid is produced during intense exercise when the body doesn't get enough oxygen to meet its energy needs. The buildup of lactic acid in muscles can cause fatigue and muscle soreness. The carbonic acid/bicarbonate buffer system can also help to buffer the excess lactic acid produced during exercise, preventing the blood from becoming too acidic.
