Food web shows the cycle of energy that is transferred from one organism to another in that web.

<u>Explanation:</u>

A food web (or nourishment cycle) is the natural interconnection of natural pecking orders and a graphical portrayal (generally a picture) of what-eats-what in an environmental network. Another name for nourishment web is customer asset framework.

Arrows on a food web, or food web, speak to the progression of vitality. The situation of the bolts in an evolved way of life or nourishment web is significant. The bolts consistently show the heading of the vitality as it is moved starting with one life form then onto the next. The progression of vitality can likewise be spoken to inside a vitality pyramid.

Given the following partial (valence-level) electron configurations,<br> (a) identify each element,

Kamila [148]

The arrangement of electrons within an atom is called the electronic configuration and the electrons are filled up according to the energy of the levels as: 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f.

<h3>What is the difference between electron configuration and valence electron configuration?</h3>

Electron configuration is the number of electrons that are present in the atom and is repressed through the different sub-shells. So for example, the electron configuration for oxygen is 1s^2 2s^2 2p^4. While the valence electrons only refer to the electrons in the outermost shell of the atom.

<h3>What is a partial orbital diagram?</h3>

A partial orbital diagram shows only the highest energy sublevels being filled. Al (Z = 13) 1s22s22p63s23p1. A condensed electron configuration has the element symbol of the previous noble gas in square brackets. Al has the condensed configuration [Ne]3s23p1.

If you performed this experiment using mgcl2 as the solute would the molar concentration of mgcl2 that is isotonic to the potato

Mama L [17]

The answer to this question would be: lower molar concentration

Osmotic pressure is influenced by the number of ions and the concentration of the molecule in the solution. In NaCl, the molecule will split into 1 Na+ ion and 1 Cl- ion which results in 2 ions per compound. In MgCl2, the compound will split into 1 Mg2+ ion and 2 Cl- ion which results in 3 ions. Therefore, the osmotic pressure of MgCl2 will be 3/2 times of NaCl.
MgCl2 will need less concentration to achieve same osmotic pressure as NaCl. If the MgCl2 solution is isotonic with NaCl, the concentration of MgCl2 would be lower than NaCl

Constructive and destructive process.

Aleks [24]

Answer:

again here

Explanation:

Collection and analysis of data indicate that constructive forces include crustal deformation, faulting, volcanic eruption and deposition of sediment, while destructive forces include weathering and erosion. I can explain how constructive and destructive forces affect the nature of landforms on Earth.

How are covalent compounds similar to acids?

Ivan

Answer:

Acids are substances that produce an create high amounts of H+ ions when dissolved in water. And because the hydrogen bond's with non-metals,it forms covalent bonds. So,all acids are covalent bonds.

When a pure sample of KNO3(s) spontaneously dissolves in water at room temperature, the solution becomes quite cold to the touch

jekas [21]

The enthalpy of the solution is <u>positive </u>and the entropy is <u>positive</u>.

Potassium trioxonitrate (V) KNO₃(s) is a strong oxidizing solid substance that when dissolved in water changes to aqueous solution.

In its aqueous solution state, the randomness of molecules increases as a result of that the entropy will also increase leading to the positive state of the entropy.

Similarly, provided that the solution becomes quite cold to the touch, the enthalpy is also in it positive state.

Therefore, we can conclude that the enthalpy of the solution is <u>positive </u>and the entropy is <u>positive</u>.
