Answer:
Dimer of two peptide chains with 1 mole of molybdenum metal each.
Explanation:
Percentage of molybdenum in protein = 0.08%
Molecular mass of nitrate reductase = 240,000 g
Mass of molybdenum = x
Moles of molybdenum =
Each peptide chain of nitrate reductase contain 1 mole of molybdenum.
This means that nitrate reductase is composed of to two peptide chains. And in each peptide there is a single mole of molybdenum metal.
Answer: -
Mass of Hydrated KAl(SO₄)₂ = 2.0 g
Molar mass of anhydrous KAl(SO₄)₂ = 258.20 g/ mol
Mass of of anhydrous KAl(SO₄)₂ = mass of the 2nd heating = A
The mass of water released = mass of the Aluminum Cup + 2.0 grams of KAl(SO₄)₂ - mass of the 2nd heating
= H g
Moles of water released =
Moles of anhydrous KAl(SO₄)₂ =
Required ratio =
The energy of a photon that has a frequency of 2.3 x 10¹⁴ Hz is 1.524 × 10-¹⁹J
HOW TO CALCULATE ENERGY OF A PHOTON:
- The energy of a photon can be calculated by using the formula as follows:
E = hf
Where;
E = energy of photon (J)
h = Planck's constant (6.626 × 10-³⁴J)
f = frequency of photon (Hz)
- According to this question, a photon has a frequency of frequency of 2.3 x 10¹⁴ Hz. The energy of the photon can be calculated as follows:
E = 6.626 × 10-³⁴ × 2.3 × 10¹⁴
E = 15.24 × 10-³⁴+¹⁴
E = 15.24 × 10-²⁰J
E = 1.524 × 10-¹⁹J
- Therefore, energy of a photon that has a frequency of 2.3 x 10¹⁴ Hz is 1.524 × 10-¹⁹J

A metamorphic rock can turn into an igneous rock if it becomes hot enough to melt. Then, when it cools enough to become solid the result will be an igneous rock. An igneous rock can become metamorphic, if it is under pressure when it is heated. The pressure will keep the rock from melting but will allow the atoms to unite with our atoms forming new minerals when the rock cools. The resulting metamorphic rock will have some new minerals that the igneous didn't have. The new minerals will have a ordered physical arrangement unlike the random mixture of an igneous rock.
