Answer:
CO2; succinyl-SCoA
Explanation:
Citric acid cycle, also called Krebs cycle is the second stage of aerobic cellular respiration, which occurs in the mitochondrion. The kreb's cycle is made up of 7 distinct steps, with each involving series of enzymatic reactions.
According to this question, step 3 and 4 of the citric acid cycle involves an oxidation and decarboxylation reaction to produce 2 molecules of carbon dioxide (CO2) and a 4-carbon compound called succinyl group. A coenzyme A binds to the succinyl group to form succinyl-SCoA.

What is the oxidation state of Carbon in CaC2O4?
Answer:
The oxidation state of carbon in CaC204 is 3
Answer:The oxidation number of the carbons + the oxidation numbers of the oxygens must equal -2. Carbons + (-8) = -2 so the oxidation number of the carbons must be +6. Since there are 2 carbon atoms each must contribute +3 each. What is the oxidation number of S in Na2S2O3?
Explanation:
The oxidation state of Oxygen is -2 and that of Calcium is +2. There are four oxygen atoms which amounts to -8 charge. This leaves a charge of +6 on Carbon
balance FeCl3 + MgO ---> Fe2O3 + MgCl2
Answer: The balanced equation is [tex]2FeCl_{3} + 3MgO \rightarrow Fe_{2}O_{3} + 3MgCl_{2}[/tex]
Explanation:
The given reaction equation is as follows.
[tex]FeCl_{3} + MgO \rightarrow Fe_{2}O_{3} + MgCl_{2}[/tex]
Here, number of atoms present on reactant side are as follows.
Fe = 1Cl = 3Mg = 1O = 1Number of atoms on product side are as follows.
Fe = 2Cl = 2Mg = 1O = 3To balance this equation, multiply [tex]FeCl_{3}[/tex] by 2 and MgO by 3 on reactant side. Also, multiply [tex]MgCl_{2}[/tex] by 3 on product side. Therefore, the equation can be rewritten as follows.
[tex]2FeCl_{3} + 3MgO \rightarrow Fe_{2}O_{3} + 3MgCl_{2}[/tex]
Hence, number of atoms on reactant side are as follows.
Fe = 2Cl = 6Mg = 3O = 3Number of atoms on product side are as follows.
Fe = 2Cl = 6Mg = 3O = 3Since, this equation contains same number of atoms on both reactant and product side. Therefore, this equation is now balanced equation.
Thus, we can conclude that the balanced equation is [tex]2FeCl_{3} + 3MgO \rightarrow Fe_{2}O_{3} + 3MgCl_{2}[/tex].
What is the relationship between a planet's period of rotation and diameter?
There is, however, a relationship between a planet's distance from the Sun and its period of revolution. Kepler's third law of planetary motion says that the square of the planet's orbital period is proportional to the cube of its semimajor axis.
According to Kepler's third law of planetary motion, a planet's semimajor axis and orbital period are inversely proportional.
What is Kepler's third law?Kepler's third law is defined as the cubes of the semi-major axes of the planets' orbits are directly proportional to the squares of the planets' orbital periods. According to Kepler's Third Law, as an orbiting planet's radius increases, so does the time of its orbit around the Sun. A planet's orbits around the sun are accurately described by Kepler's third law in terms of their period and distance.
The cube (third power) of an orbital radius is directly related to the square (second power) of a planet's period (P2 = R3). The period of revolution shortens as the planet's distance from the sun rises.
Thus, according to Kepler's third law of planetary motion, a planet's semimajor axis and orbital period are inversely proportional.

Un átomo es la parte más pequeña de materia que puede combinarse químicamente con otro y mantiene todas las propiedades de un elemento.
Los átomos se combinan para formar moléculas que luego interactúan para formar sólidos, líquidos y gases.
Su estructura está compuesta por diferentes combinaciones de tres sub-partículas: los neutrones, los protones y los electrones. A su vez posee dos regiones diferentes: el núcleo, donde están los protones y los neutrones, y la nube u orbitales electrónicos, donde se encuentran los electrones.
Entonces, los neutrones se encuentran dentro del núcleo.

Molar mass of hypomanganous acid. (H3MnO4) = 1(3) + 55 + 16(4)
= 3 + 55 + 64
= 122g/mol

Which statement is true about the rotational period of the moon?
greater than the revolution period around Earth

less than the revolution period around Earth

The statement is true about the rotational period of the moon " the rotational period of the moon is equal to the revolution period around Earth."
What is rotational period?A celestial object's rotation period may relate towards its sidereal rotation period, which is the time it takes for the object to complete one revolution around in its axis of rotation in sidereal seems like to the background stars.
What is revolution period?The orbital period is also known as the revolution period. it takes for one astronomical object to complete one cycle around another. It refers to planets and asteroids orbiting the Sun, moons orbiting planets, planetary systems orbiting other stars, or double stars in astronomy.
What is moon?In the night sky, the moon is just the brightest object. The moon doesn't at all produce its own light. It has no radiance. That is visible because the sun's light bounces off of it.
The rotational period of the moon is equal to the revolution period around Earth because the moon's rate of spin becomes tidally locked to its rate of revolution, it maintains the same face oriented towards the Earth In other words, every time the moon rounds the Earth, it rotates exactly once.
Therefore, the rotational period of the moon is equal to the revolution period around Earth will be correct answer.

Explanation:
A gas is confined in a cylinder fitted with a movable piston. At 27ºC, the gas occupies a volume of 2.0 L under a pressure of 3.0 atm. The gas is heated to 47ºC and compressed to 5.0 atm. What volume does the gas occupy in its final state?
A: 0.78 L
B:1.3 L
C:2.1 L
D:0.48 L
The volume of the gas is 1.27 L at a temperature is 47°C and the pressure is 5.0 atm. Therefore, option (B) is correct.
What is the ideal gas equation?The ideal gas equation is described as the equation of the state of a perfect gas. The ideal gas equation is the product of the pressure and volume of one-mole gas is equal to the multiplication of the absolute temperature and gas constant.
The mathematical equation for a perfect gas is as follows:
PV = nRT
where n is the moles of an ideal gas, P is the pressure of the gas, V is the volume, and R is the universal gas constant.
Given, the initial volume of the gas, V₁ = 2.0 L
The initial temperature of the gas, T₁ = 27° C = 300.15 K
The initial pressure of the gas, P₁ = 3.0 atm
The final temperature of the gas, T₂ = 47° C = 320.15 K
The initial pressure of the gas, P₂ = 5.0 atm
We know that for an ideal gas:
[tex]\frac{P_1V_1}{T_1} =\frac{P_2V_2}{T_2}[/tex]
[tex]V_2=\frac{P_1V_1T_2}{T_1P_2}[/tex]
[tex]V_2= \frac{3.0\times2.0\times320.15}{5.0\times 300.15}[/tex]
[tex]V_2= 1.27 L[/tex]
Therefore, the volume of the gas in its final state is equal to 1.27 L when the gas is heated to 47ºC and compressed to 5.0 atm.

A 25.0 L tank of nitrogen gas is at 25 oC and 2.05 atm . If the temperature stays at 25 oC and the volume is decreased to 14.5 L , what is the new pressure?
Answer:
[tex]\boxed {\boxed {\sf P_2 \approx 3.53 \ atm}}[/tex]
Explanation:
In this problem, the temperature stays constant. The volume and pressure change, so we use Boyle's Law. This states that the pressure of a gas is inversely proportional to the volume. The formula is:
[tex]P_1V_1=P_2V_2[/tex]
Now we can substitute any known values into the formula.
Originally, the gas has a volume of 25.0 liters and a pressure of 2.05 atmospheres.
[tex]25.0 \ L * 2.05 \ atm = P_2V_2[/tex]
The volume is decreased to 14.5 liters, but the pressure is unknown.
[tex]25.0 \ L * 2.05 \ atm = P_2 * 14.5 \ L[/tex]
Since we are solving for the new pressure, or P₂, we must isolate the variable. It is being multiplied by 14.5 liters and the inverse of multiplication is division. Divide both sides by 14.5 L .
[tex]\frac {25.0 \ L * 2.05 \ atm }{14.5 \ L}=\frac{P_2 *14.5 \ L}{14.5 \ L}[/tex]
[tex]\frac {25.0 \ L * 2.05 \ atm }{14.5 \ L}= P_2[/tex]
The units of liters cancel.
[tex]\frac {25.0 * 2.05 \ atm }{14.5 }=P_2[/tex]
[tex]\frac {50.25\ atm }{14.5 }=P_2[/tex]
[tex]3.53448276 \ atm = P_2[/tex]
The original values of volume and pressure have 3 significant figures, so our answer must have the same.
For the number we found, that is the hundredth place.
3.53448276The 4 in the thousandth place (in bold above) tells us to leave the 3 in the hundredth place.
[tex]3.53 \ atm \approx P_2[/tex]
The new pressure is approximately 3.53 atmospheres.
