Why wasn't oxidation type chemical weathering common more than 2 billion years ago?

Chemistry
1 answer:
scZoUnD [109]3 years ago
6 0

Answer:

            Due to deficiency of Oxygen in atmosphere.

Explanation:

                   Oxidation is defined in two ways, 1) The addition of Oxygen and Removal of Hydrogen 2) The removal of electrons.

                   We will discuss the first definition for this question. The addition of oxygen to various compounds results in the oxidation of that compound.

Example: Oxidation of Methane;

                                   CH₄  +  2 O₂    →    CO₂  +  2 H₂O

In this example oxygen is added to methane and hydrogen is being removed from methane.

Oxidation type chemical weathering common more than 2 billion years ago because of less amount of Oxygen in atmosphere and the oxygen which was produced by plants reacted with different metals like Iron forming precipitates which precipitated to the bottom of oceans.

Suppose you are trying to separate three Proteins using Gel-Filtration chromatography. The sizes of each are given below:
Damm [24]

<u>Answer:</u> The correct answer is Protein B.

<u>Explanation:</u>

Gel-filtration chromatography is a separation technique that is based on the size of the molecules in a compound. It is also known as size-exclusion chromatography in which the eluent (carrier) used is an aqueous solution.

The matrix that is used is a porous material. When the sample is inserted in the column, the smaller particles interact strongly with the matrix than the large ones. Thus, as the eluent is passed through the matrix, larger molecules come out first, and the smallest molecule comes out last.

Given sizes of the proteins:

Protein A: 1200 kDa

Protein B: 2000 kDa

Protein C: 800 kDa

As protein B has the largest size of all the given proteins, it will emerge out first from the column.

Hence, the correct answer is Protein B.

How many moles are in 110 grams of nahco3
yuradex [85]
Molar mass NaHCO₃ = 23 + 1 + 12 + 16 x 3 = 84 g/mol

1 mole ---------- 84 g
? mole ---------- 110 g

moles NaHCO₃ = 110 . 1 / 84

moles NaHCO₃ = 110 / 84

= 1.309 moles

hope this helps!

Which phase transition, solid to liquid or liquid to gas, results in the largest increase in entropy
Licemer1 [7]

The liquid to gas phase transition results in the largest increase in entropy.

<h3>What is Entropy?</h3>
  • Entropy is a measureable physical characteristic and a scientific notion that is frequently connected to a condition of disorder, unpredictability, or uncertainty.
  • From classical thermodynamics, where it was originally recognized, through the microscopic description of nature in statistical physics, to the fundamentals of information theory, the phrase and concept are utilized in a variety of disciplines.
  • It has numerous applications in physics and chemistry, biological systems and how they relate to life, cosmology, economics, sociology, weather science, and information systems, especially the exchange of information.
  • Entropy has the effect of making some processes impossible or irreversible, in addition to the necessity that they not go against the first law of thermodynamics, which is the conservation of energy.

How is the structure of atoms altered during fission and fusion?
Dmitriy789 [7]
At first sight it doesn't bode well. The key is in how firmly the protons and neutrons are held together. In the event that an atomic response produces cores that are more firmly bound than the firsts then vitality will be created, if not you should place vitality into make the response happen.
