If I have 0.070 moles of gas at a pressure of 0.20 atm and at a temperature of 8.00°C,

The P:OP:O ratio is the amount of inorganic phosphate incorporated into ATP per atom of oxygen consumed. It represents the coupl

Ray Of Light [21]

Answer:

For NADH; P:O = 2.5

For FADH ₂; P : O = 1.5

Explanation:

The P:O (phosphate:oxygen) ratio represents the amount of inorganic phosphate, Pi used per atom of oxygen consume to synthesize ATP.

The Chemiosmotic theory predicts H⁺:O and H⁺:ATP ratios. Experimentally these appear to be 10 and 4 respectively when NADH is the substrate, equivalent to a P:O ratio of 2.5, and 6 and 4 respectively for FAD-linked substrates (e.g. succinate), equivalent to a P:O ratio of 1.5.

1. Electron flow from NADH to O₂ pumps protons at three sites to yield 3 ATP (P:O = 2.5)

For NADH: 10 H ⁺ translocated/O (2e -)

ATP/2e - = (10 H⁺/ 4 H +) = 2.5

2. Succinate (via FADH2) bypasses site 1 giving 2 ATP (P : O = 1.5)

For FADH ₂= 6 H ⁺/O(2e - )

ATP/2e - = (6 H +/ 4 H +) = 1.5

Can someone explain how you get the answers to these questions??<br> i really need help !!!

The balanced chemical equations are as follows:

AlBr₃ + K → 3 KBr + Al
FeO + PdF₂ → FeF₂ + PdO
P₄ + 6 Br₂ → 4 PBr₃
2 LiCl + Br₂ → 2 LiBr + Cl₂

<h3>What are balanced chemical equations?</h3>

Balanced chemical equations in which the moles of atoms of elements taking part in a reaction are balanced on both sides of the equation.

The balancing of chemical equations follows the law of conservation of mass which states that matter can neither be created nor destroyed.

In balancing of chemical equations, the following steps are follows:

ensure that the all the substances involved are written in the equation
do not alter the formula of compounds or molecules
add numerical coefficients in front of the compounds and molecules to ensure that the moles of atoms of elements are balanced on both sides of the equation

In conclusion, a balanced chemical equation obeys the law of conservation of mass.

Enter your answer in the provided box. Before arc welding was developed, a displacement reaction involving aluminum and iron(III

Likurg_2 [28]

Answer:

grams of iron = 2262.4 g

Explanation:

The balanced chemical equation should be represented first.

2Al + Fe2O3 → Al2O3 + 2Fe

find the limiting reactants by converting to moles.

covert 1.64 kg to grams = 1640 g

moles = mass/molar mass = 1640/27 = 60.7407407407 moles

60.7407407407 × 1 mol-rxn /2 = 30.37 mol-rxn

The limiting reactant is Fe2O3 Therefore it will determine the yield of Iron

2Al + Fe2O3 → Al2O3 + 2Fe

molar mass of Fe2O3 = 56 × 2 + 16 × 3 = 112 + 48 = 160 g

atomic mass of iron = 56

mass of iron in the reaction = 56 × 2 = 112 g

moles = mass/molar mass

mass = moles × molar mass

mass = 20.2 × 160 = 3232 g

if 160 g of Fe2O3 give 112 g of iron

3232 g of Fe2O3 will give ? grams of iron

grams of iron = 3232 × 112/ 160

grams of iron = 361984 /160

grams of iron = 2262.4 g

Identify one advantage to each of the following models of electron configuration:

Crank

Answer:

Dot structures make it easy to count electrons and they show the number of electrons in each electron shell.

Arrow and line diagrams show the spin of electrons and show every orbital.

Written configurations require minimal space and show the distribution of electrons between subshells.
