It’s the measure of spaces between objects. It affects groundwater infiltration by having more water fill the spaces between it. For example, is you have bigger rocks the spaces between it are bigger therefore the groundwater infiltration rate is faster. If the rocks are smaller, they are tightly packed and it’s not easy for groundwater infiltration.

For a substance to have absolute "zero entropy," the following conditions must be true. Select all of the correct answers.-there

tresset_1 [31]

There must be just one microstate, the solid must be ionic, and it must be completely crystalline.

The concept of entropy with examples.

A measure of the system's energy distribution's entropy. We come across evidence that the cosmos aims for the highest level of entropy in many facets of human life. A campfire is an example of entropy. Hard wood melts and transforms into ash, air, and fumes, all of which disperse energy faster than liquid fuel.

In what units is entropy measured?

J/K is the unit of measurement for entropy. The absolute, or Kelvin, digital thermometer must be used to calculate the heat required by this equation. On this scale, zero is the lowest possible temperature that any substance might experience. At absolute zero, all atom motion ceases, and the disorder in a substance is zero (0 K).

1.) Why does the heart rate speed up during exercise?

Yakvenalex [24]

1.) When a man is engaged to continuous exercise or work, not only his muscles are working but also there is increase in the rate of respiration too. This accelerated rate of respiration and heartbeat provides more oxygen and food to the body. So all the organs and organ systems work in coordination. 2.) I'm sorry that I don't know the answer to your question. The one which I know, I have already written.

For each of the following compounds, state whether it is ionic or covalent, and if it is ionic, write the symbols for the ions i

kupik [55]

Answer :

Covalent compound : It is defined as the compound which is formed by the sharing of electrons between the atoms forming a compound.

The covalent compound are usually formed when two non-metals react.

Ionic compound : It is defined as the compound which is formed when electron gets transferred from one atom to another atom.

All the polyatomic ions always form an ionic compound.

Polyatomic ions : It is a charged species that composed of two or more atoms and these charged species are bonded by the covalent bond.

For the given options:

Option A: $KClO_4$

This compound is formed by the combination of potassium, $K^+$ which is a metal and $ClO_4^-$ ion which is a polyatomic ion. Thus, it will form an ionic compound.

Option B: $Mg(C_2H_3O_2)_2$

This compound is formed by the combination of magnesium, $Mg^{2+}$ which is a metal and $C_2H_3O_2^{-}$ ion which is a polyatomic ion. Thus, it will form an ionic compound.

Option C: $H_2S$

Hydrogen and sulfur, both are non-metals and they will form a covalent compound.

Option D: $Ag_2S$

This compound is formed by the combination of silver, $Ag^{+}$ which is a metal and sulfur, $S^{2-}$ which is a non-metal. Thus, it will form an ionic compound.

Option E: $N_2Cl_4$

Nitrogen and chlorine, both are non-metals and they will form a covalent compound.

Option F: $Co(NO_3)_2$

This compound is formed by the combination of cobalt, $Co^{2+}$ which is a metal and $NO_3^{-}$ ion which is a polyatomic ion. Thus, it will form an ionic compound.
