Breaking a solid reactant into pieces results in

Hitman42 [59]

Answer:

If one of the reactants is a solid, only the particles at the surface can partake in the reaction. Breaking the reactant into smaller pieces increases the surface and more particles are exposed to the reaction mixture. This results in an increased frequency of collisions and therefore a faster rate of reaction

Calculate the number of ATP generated from one saturated 10 ‑carbon fatty acid. Assume that each NADH molecule generates 2.5 ATP

larisa86 [58]

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

if 0.40 mol of h2 and .15 mol of o2 were to reat as completely as possible to produce h20, what mass of the reactant would remai

Sveta_85 [38]

Answer:

0.2g

Explanation:

Given parameters:

Number of moles of H₂ = 0.4mol

Number of moles of O₂ = 0.15mol

Unknown:

Mass of reactant that would remain = ?

Solution:

To solve this problem, we need to know the limiting reactant which is the one in short supply in the given reaction.

The expression of the reaction is :

2H₂ + O₂ → 2H₂O

2 mole of H₂ will combine with 1 mole of O₂

But given; 0.4 mole of H₂ we will require $\frac{0.4}{2}$ = 0.2mole of O₂

The given number of oxygen gas is 0.15mole and it is the limiting reactant.

Hydrogen gas is in excess;

1 mole of oxygen gas will combine with 2 mole of hydrogen gas

0.15 mole of oxygen gas will require 0.15 x 2 = 0.3mole of hydrogen gas

Now, the excess mole of hydrogen gas = 0.4 mole - 0.3 mole = 0.1mole

Mass of hydrogen gas = number of mole x molar mass

Molar mass of hydrogen gas = 2(1) = 2g/mol

Mass of hydrogen gas = 0.1 x 2 = 0.2g
