Is usually categorized to a specific area in the state known as a soil series
Vikentia [17]

Answer:

Soil series as established by the National Cooperative Soil Survey of the United States Department of Agriculture (USDA) Natural Resources Conservation Service are a level of classification in the USDA Soil Taxonomy classification system hierarchy. The actual object of classification is the so-called soil individual, or pedon.[1] Soil series consist of pedons that are grouped together because of their similar pedogenesis, soil chemistry, and physical properties. More specifically, each series consists of pedons having soil horizons that are similar in soil color, soil texture, soil structure, soil pH, consistence, mineral and chemical composition, and arrangement in the soil profile.[2] These result in soils which perform similarly for land use purposes.

Anon25 [30]

Answer:

<u>thermal conductivity:</u> the rate at which heat is transferred by conduction through a unit cross-section area of a material, when a temperature gradient exits perpendicular to the area

<u>electrical conductivity:</u> the measure of the amount of electrical current a material can carry or it's ability to carry a current

<u>solubility:</u> the ability to be dissolved, especially in water

<u>magnetism:</u> a physical phenomenon produced by the motion of electric charge, resulting in attractive and repulsive forces between objects

<u>melting point:</u> the temperature at which a given solid will melt.

<u>boiling point:</u> the temperature at which a liquid boils and turns to vapor

How many molecules of ammonia (NH3) are contained in 10 moles of NH3? Please provide the work if you could :)
nlexa [21]
<span>Avogadro's number represents the number of units in one mole of any substance. This has the value of 6.022 x 10^23 units / mole. This number can be used to convert the number of atoms or molecules into number of moles. We do as follows:

 </span>10 mol NH3 ( 6.022 x 10^23 molecules / 1 mol ) = 6.022x10^24 molecules NH3
