In what way do the oceans and the forests perform a similar function in the carbon cycle, under normal conditions?.
ikadub [295]

Both take carbon dioxide out of the atmosphere.

The ocean absorbs much of the carbon dioxide released when fossil fuels are burned. This extra carbon dioxide lowers the ocean's pH through a process called ocean acidification. Both are important elements for all life on earth. Relationship between the water cycle and the carbon cycle. The sun's energy drives both the carbon cycle and the water cycle.

Recall that sunlight water and carbon dioxide combine in green plants via photosynthesis to produce carbohydrates. The ocean also regulates the Earth's climate. They determine the weather by telling temperatures and determining rainfall, droughts, and floods. It is also the world's largest carbon sink, with an estimated 83% of the global carbon cycle circulating in seawater.

What is reduced and what is oxidized in the reaction between a monosaccharide and a ferric ion?
Furkat [3]

In the reaction between a monosaccharide and a ferric ion, The carbonyl carbon is oxidized to a carboxyl group, the cupric ion is reduced.

Chemical reactions often involve color changes, temperature changes, gas evolution, or precipitate formation. Simple examples of everyday reactions are digestion, combustion, and cooking. A physical reaction is a reaction in which a change in matter or physical properties of matter occurs. Physical properties include density, mass, and volume. The definition of a physical reaction is a reaction in which molecules undergo molecular rearrangements but do not change chemically.

As the name suggests, simple reactants form or synthesize more complex products. The basic form of a synthetic reaction is A + B → AB. A simple example of a synthetic reaction is the formation of water from its elements hydrogen and oxygen: 2 H2(g) + O2(g) → 2 H2O(g)9 May 2019

identify the precipitate(s) of the reaction that occurs when a silver nitrate solution is mixed with a sodium chloride solution.
zlopas [31]

The precipitate of reaction that occurs when silver nitrate solution is mixed with sodium chloride solution is of silver chloride (AgCI).

The chemical equation for this precipitation reaction is as following:

AgNO3(aq) + NaCl(aq) --> AgCl(s) [precipitate]+NaNO3(aq)

  • Silver Chloride is a chemical compound which is poorly soluble in water because the chemical bond between Ag+ and Cl is very strong as the two ions are nearly the same size and have similar electronic densities.
  • If the chemical bond is strong, it is difficult for water molecules to break this bond to surround the individual ions, thus solubility will decrease.

Give the electron confiuration of Chromium (Cr), atomic number 24.
nadezda [96]
<span>Chromium is a transition metal and it has 24 electrons and here is the orbital diagram. If we're going to make this short hand and make the electron configurationfor this we would make this 1s2, 2s2, 2p6, 3s2, 3p6, 4s2, 3d4 okay from now on every time you see 3d4 you're going to change it, we do not like 3d4.</span>
