Which are factors scientists use to classify orders of soil?

Chemistry
1 answer:
Sergio039 [100]2 years ago
8 0

Answer:

Soils are a function of the five soil-forming factors: climate, organisms, relief, parent material, and time. Each of these factors range on a continuum, so the different soils of the world number in the thousands. Soil scientists recognize 12 major orders of soils.

The Mr is the mass numbers of each element added up so…. Fe = 56, O=16, H=1 … now add these up with the number of each element -> there’s 1 Fe, and 3 Os and 3 Hs as they are in brackets with a 3 outside-> (56+16+16+16+1+1+1=107) … your answer is 107

A body found with rigor throughout the body
-BARSIC- [3]

Answer:

Can you move a body in rigor mortis?

Rigor mortis -- the lay version of it is stiffening of the joints. It really had nothing to do with the joints. It's the lack of chemical in the body, ATP, which is Adenosine Triphosphate. It goes away and you can now move the extremities easily after rigor mortis is gone away.

3. 25. The temperatures favorable for the growth of most bacteria are
kvasek [131]

B.

about the same as for humans

Explanation:

This is why most bacteria, during research in labs, are incubated at 37 degrees centigrade, about the same as human body temperature. In addition, harmful and beneficial bacteria thrive in the human body due to the favorable temperatures for growth and reproduction. To try and fight an infection, the body also tries to raise the body temperatures above the optimal for the bacteria  growth (the reason one has a fever in case of infection).

A flashlight battery is hooked to a toy motor, and then the battery and the connections are sprayed with a water-proof coating.
denis-greek [22]

Explanation:

Formula to calculate work done by motor is as follows.

         Work done by motor = mass \times g \times height

where,   g = gravitational constant = 10 m/s^{2}

Therefore, work done by motor is as follows.

 Work done by motor = 1.00 kg \times 10 m/s^{2} \times 10.0 m  

                                  = 100.0 J

Now, heat lost by water will be calculated as follows.

            q = mC \times \Delta T

                = g \times 4.184 J/g^{o}C \times 0.024^{o}C

                = 10.0 J

Hence, heat gained by motor = heat lost by water

As, heat gained by motor = 10.0 J

So, change in energy = heat gained - work done

Therefore, change in energy will be calculated as follows.  

   Change in energy = heat gained - work done

                                  = (10.0 J) - (100.0 J)

                                   = -90.0 J

Thus, we can conclude that change in the energy of the battery contents is -90.0 J.

What is the percent by volume of ethanol (C2H60, or ethyl alcohol) in the final solution when 90 mL of ethanol is diluted to a v
r-ruslan [8.4K]

Answer:

16.0%.

Explanation:

Volume percent of a substance is the ratio of the substance volume to the solution volume multiplied by 100.

V % of ethanol = (volume of ethanol / volume of the solution) x 100.

volume of ethanol = 90.0 mL, volume of the solution = 550.0 mL.

∴ V % of ethanol = (90.0 mL / 550.0 mL) x 100 = 16.36% ≅ 16.0%.
