Answer:

Total ATP molecules produced = 66 molecules of ATP

Explanation:

A 10-carbon fatty acid when it has undergone complete oxidation will yield 5 acetyl-CoA molecules and 4 FADH₂ and 4 NADH molecules each. Each of the 5 acetyl-CoA molecules enters into the citric acid cycle and is completely oxidized to yield further ATP and  FADH₂ and NADH molecules.

The total yield of ATP in the various enzymatic step is calculated below:

Acyl-CoA dehydrodenase = 4 FADH₂

β-Hydroxyacyl-CoA dehydrogenase = 4 NADH

Isocitrate dehydrogenase = 5 NADH

α-Ketoglutarate dehydrogenase = 5 NADH

Succinyl-CoA synthase = 5 ATP (from substrate-level phosphorylation of GDP)

Succinate dehydrogenase = 5 FADH₂

Malate dehydrogenase = 5 NADH

Total ATP  from FADH₂ molecoles = 9 * 1.5 = 13.5

Total NADH molecules = 19 * 2.5 = 47.5

Total ATP molecules produced = 13.5 + 47.5 + 5

Total ATP molecules produced = 66 molecules of ATP

How much lead(II) chromate (PbCrO4) is precipitated by mixing 100 mL of aqueous 3 M
ICE Princess25 [194]

Answer:

38.8 g of PbCrO₄ are precipitated from the reaction

Explanation:

We have the following chemical reaction:

K₂CrO₄ (aq) + Pb(NO₃)₂ (aq) → 2 KNO₃ (aq) + PbCrO₄ (s)

where:

(aq) - aqueous

(s) - solid

Now we use the following formula to calculate the number of moles:

molar concentration = number of moles / volume (L)

number of moles = molar concentration × volume (L)

number of moles of K₂CrO₄ = 3 × 0.1 = 0.3 moles

number of moles of Pb(NO₃)₂ = 2 × 0.1 = 0.2 moles

We see from the chemical reaction that 1 mole of K₂CrO₄ will react with 1 mole of Pb(NO₃)₂ so 0.3 moles of K₂CrO₄ will react with 0.3 moles of Pb(NO₃)₂ but we have only 0.2 moles of Pb(NO₃)₂ available, so the limiting reactant is Pb(NO₃)₂. Taking this in account we devise the following reasoning:

if           1 moles of Pb(NO₃)₂ produces 1 mole of PbCrO₄

then     0.2 moles of Pb(NO₃)₂ produces X moles of PbCrO₄

X = 0.2 moles of PbCrO₄

number of moles = mass / molar weight

mass = number of moles × molar weight

mass of PbCrO₄ = 0.2 × 194 = 38.8 g

Help me!!!<br> Pleaseeee!!!!
Sidana [21]

Answer:

0.862 J/gºC

Explanation:

The following data were obtained from the question:

Mass of metal (Mₘ) = 50 g

Initial temperature of metal (Tₘ) = 100 °C

Mass of water (Mᵥᵥ) = 400 g

Initial temperature of water (Tᵥᵥ) = 20 °C

Equilibrium temperature (Tₑ) = 22 °C

Specific heat capacity of water (Cᵥᵥ) = 4.2 J/gºC

Specific heat capacity of metal (Cₘ) =?

The specific heat capacity of the metal can be obtained as follow:

Heat lost by metal = MₘCₘ(Tₘ – Tₑ)

= 50 × Cₘ × (100 – 22)

= 50 × Cₘ × 78

= 3900 × Cₘ

Heat gained by water = MᵥᵥCᵥᵥ(Tₑ – Tᵥᵥ)

= 400 × 4.2 × (22 – 20)

= 400 × 4.2 × 2

= 3360 J

Heat lost by metal = Heat gained by water

3900 × Cₘ = 3360

Divide both side by 3900

Cₘ = 3360 / 3900

Cₘ = 0.862 J/gºC

Therefore, the specific heat capacity of the metal is 0.862 J/gºC

MULTIPLE CHOICE QUESTION
7nadin3 [17]

Answer:

Shorter

Explanation:

As a wavelength increases in size, its frequency, and energy (E) decrease. From these equations, you may realize that as the frequency increases, the wavelength gets shorter. As the frequency decreases, the wavelength gets longer. There are two basic types of waves: mechanical and electromagnetic.

How would you obtain pure sugar from a mixture of sugar, charcoal, and copper?
beks73 [17]
Pure sugar can be obtained from sugar solution by the process of crystallization. It involves heating which leads to evaporation of water to make the solution saturated. The saturated solution when left undisturbed convert to pure crystals of the sugar.
