The statement that is not true of the reaction producing malonyl-coa during fatty acid synthesis is "one mole of ATP is converted to ADP Pi for each malonyl-coa synthesized." The reaction actually requires two moles of ATP for each malonyl-coa synthesized.
The statement that is not true of the reaction producing malonyl-CoA during fatty acid synthesis is: "It requires acyl carrier protein (ACP)." The other statements are accurate regarding the production of malonyl-CoA. In this reaction, acetyl-CoA carboxylase enzyme is involved, which requires biotin and CO2 (or bicarbonate), and converts one mole of ATP to ADP and Pi for each malonyl-CoA synthesized. This reaction is also stimulated by citrate. However, ACP is not required in this specific reaction; it plays a role in later steps of fatty acid synthesis.

The number of moles water produced by the complete reaction of

109 g of hydrogen. 99 is given  below:

Moles in chemistry are a unit of measurement used to quantify the amount of substance in a given sample. It is defined as the amount of a substance that contains the same number of particles as there are atoms in 12 grams of Carbon-12. This is known as Avogadro's number and is equal to 6.02 x 10^23. The mole allows scientists to calculate the mass, volume, and number of atoms or molecules in a given sample. It is a very useful tool for measuring the amount of a substance, as it takes into account the fact that different elements and compounds have different molecular weights. The mole is also used in equations to determine the mass, volume, and concentration of a substance, as well as the number of molecules in a given sample.

The equation for the complete reaction of hydrogen is:

2H2 + O2 → 2H2O

Since one mole of hydrogen reacts with one mole of oxygen to produce two moles of water, we can calculate the number of moles of water produced by the complete reaction of 109 g of hydrogen.

Using the molar mass of hydrogen (2.016 g/mol), we can calculate the number of moles of hydrogen present:

Moles of hydrogen = (109 g H2) / (2.016 g/mol H2)

Moles of hydrogen = 53.9 mol H2

Since one mole of hydrogen reacts with one mole of oxygen to produce two moles of water, the number of moles of water produced by the complete reaction of 109 g of hydrogen is:

Moles of water = (53.9 mol H2) x (2 mol H2O/1 mol H2)

Moles of water = 107.8 mol H2O

Answer:

c. protons

Explanation:

A "proton" is a subatomic particle that is stable and is positively-charged. You will identify the number of protons that is present in the nucleus of a chemical element by its "atomic number." It gives us an identity of the element, therefore, every atom of the same element have the "same" number of protons. For example, the number of protons for "Hydrogen" is 1. This means that even if you have two atoms of Hydrogen, each of them has "1" as the number of proton.

It always takes specific quantity of energy to remove only 1 electron from an atom.

Electron is a stable sub atomic particle with a charge of negetive electricity found in all atoms and acting as the primary Carrier of electricity in solid.

The molarity of the acetic acid, when it is titrated with 0.50M NaOH, and 15.6 ml of it is required to reach the equivalence point, is 0.78 M.

The molarity of the acetic acid can be calculated using the following formula:
Molarity (M) = (Moles of Acid) / (Volume of Acid)

First, the moles of acetic acid must be determined. To do this, the moles of sodium hydroxide (NaOH) used to titrate the acetic acid must be determined.

Moles of NaOH = (Molarity of NaOH) x (Volume of NaOH)
Moles of NaOH = (0.50 mol/L) x (0.0156 L)
Moles of NaOH = 0.0078 mol

Since one mole of NaOH is needed to neutralize one mole of acetic acid, the moles of acetic acid are equal to the moles of NaOH, or 0.0078 mol.

Next, the volume of the acetic acid must be determined. Since 10.0 mL of vinegar was used, the volume of acetic acid is also 10.0 mL.

Now that the moles of acetic acid and the volume of acetic acid have been determined, the molarity of the acetic acid can be calculated.

Molarity (M) = (Moles of Acid) / (Volume of Acid)
Molarity (M) = (0.0078 mol) / (0.010 L)
Molarity (M) = 0.78 mol/L

Therefore, the molarity of the acetic acid is 0.78 mol/L.

The molarity of the acid solution is 0.0425 M.

Titration is a common laboratory technique used to determine the concentration of a substance in a solution. In a titration, a known solution (titrant) is added gradually to an unknown solution until the reaction between the two is complete.

The point at which the reaction is complete is called the endpoint, and it is typically identified by an indicator that changes color.

To calculate the molarity of the unknown acid solution, we can use the following formula:

Molarity of acid solution = (Molarity of base solution) x (Volume of base solution) / (Volume of acid solution)

In this case, we know that 25.5 mL of a 0.1 M base solution was required to titrate 60 mL of the unknown acid solution. Using the formula above, we can plug in the values:

Molarity of acid solution = (0.1 M) x (25.5 mL) / (60 mL)
Molarity of acid solution = 0.0425 M

Therefore, the molarity of the acid solution is 0.0425 M.

To determine the mass of 1.1*10^25 atoms of AgNO3, we need to first calculate the molar mass of AgNO3 and then use Avogadro's number to convert the number of atoms to mass.

The molar mass of AgNO3 can be calculated as follows:

Ag = 1 * 107.87 g/mol = 107.87 g/mol

N = 1 * 14.01 g/mol = 14.01 g/mol

O3 = 3 * 16.00 g/mol = 48.00 g/mol

Molar mass of AgNO3 = 107.87 g/mol + 14.01 g/mol + 48.00 g/mol = 169.88 g/mol

Now, we can use Avogadro's number (6.022 x 10^23) to convert the number of atoms to mass:

1.1*10^25 atoms of AgNO3 * (1 mol/6.022 x 10^23 atoms) * (169.88 g/mol) = 3.6 x 10^3 grams

Therefore, there are 3.6 x 10^3 grams in 1.1*10^25 atoms of AgNO3.

The amount of energy needed to ionize 7.5 mole of sodium is 3720 KJ.

Energy is defined as a quantitative property that is transferred to a body or a physical system and is visible in the performance of work as well as in the appearance of heat and light.

The joule is the SI unit of measurement for energy (J).

There are basically basically two types of energy.

1 mole of Na will consume 496 KJ of energy

So, 7.5 mole of Na = 7.5 x 496

                               = 3720 KJ

Answer:

Explanation:

Answer:

bonding molecular orbital is lower in energy

antibonding molecular orbital is higher in energy

Explanation:

Electrons in bonding molecular orbitals help to hold the positively charged nuclei together, and they are always lower in energy than the original atomic orbitals.

Electrons in antibonding molecular orbitals are primarily located outside the internuclear region, leading to increased repulsions between the positively charged nuclei. They are always higher in energy than the parent atomic orbitals.

The resulting gas pressure will be 512.08 torr.

By ideal gas law, PV = nRT

P = pressure

V = volume

n = number of mole of gas

R = gas constant

T = temperature

Using ideal gas law, P₁V₁/ T₁ = P₂V₂/ T₂

P₁= 402 torr

V₁ = 7.22 L

T₁ = 60.0°C

P₂ = ?

T₂ = 56° C

V₂ = 5.29 L

Put these values in formula, P₁V₁/ T₁ = P₂V₂/ T₂

P₂ =  P₁V₁T₂/ T₁ V₂

P₂ = 402 torr ×7.22 L ×56° C / 60.0°C ×5.29 L

P₂ = 512.08 torr

Hence, the resulting gas pressure will be 512.08 torr.

The ideal gas equation is formulated as: PV = nRT.

In this equation, P refers to the pressure of the ideal gas, V is the volume of the ideal gas, n is the overall quantity of ideal gas this is measured in terms of moles, R is the universal gas constant, and T is the temperature.
