Which factors affect a river's load?

Chemistry
2 answers:
nikklg [1K]3 years ago

D. because the size and shape of the slope determines weather the load can be sustained and c is correct too because the shape affects how much you can load and b. is correct as also because if the volume is very large it can affect the rivers load and flow.

Answer: d.

all of the above

Explanation:

A river load can be define as the debris or sediments carried away by the stream of river water. The materials which are translocated includes the rocks, stones and other large particles. Generally, the finer particles floats over the water surface. River slope, shape of the stream bed and volume of flow of water all are the factors which can affect the river load.

River slope will cause the erosion of surface materials by using water. Shape of the stream bed is also a factor this is because of the fact that the wider the surface covered by water more erosion can be caused. If the volume of water flowing in the stream is high the water will take away the particles by causing friction over the surface.

Answer: Product

Explanation:

A Chemical reaction shows how substances, written in symbols  known as  reactants, are converted to different substances called products. An arrow from the left hand side (reactants) points to right hand side ( products )shows the direction of  flow of reaction.

In the equation. C + O2 --------> CO2

                             reactant------> product

CO2  is the product

How do scientists distinguish between an element and a compound? List two elements and two compounds.
Vsevolod [243]
The difference between an element and a compound is that an element is composed of only one kind of atom while a compound is composed of at least 2 kinds of atoms. The properties of an element and the compound the atoms has to form are different physically and chemically.Example of element are O and H, while compound examples are H2O and H2O2.

Taking into account the definition of dilution:

  • you have to use 8.23 mL of a stock solution of 7.00 M HNO₃ to prepare 0.120 L of 0.480 M HNO₃.
  • If you dilute 20.0 mL of the stock solution to a final volume of 0.270 L , the concentration of the diluted solution is 0.518 M.

<h3>Dilution</h3>

Dilution is the process of reducing the concentration of solute in solution, which is accomplished by simply adding more solvent to the solution at the same amount of solute.

In a dilution the amount of solute does not change, but as more solvent is added, the concentration of the solute decreases, as the volume (and weight) of the solution increases.

A dilution is mathematically expressed as:

Ci×Vi = Cf×Vf

where

  • Ci: initial concentration
  • Vi: initial volume
  • Cf: final concentration
  • Vf: final volume

<h3>Volume of stock solution</h3>

In this case, you know:

  • Ci= 7 M
  • Vi= ?
  • Cf= 0.480 M
  • Vf= 0.120 L

Replacing in the definition of dilution:

7 M× Vi= 0.480 M× 0.120 L

Solving:

Vi= (0.480 M× 0.120 L)÷ 7 M

<u><em>Vi= 0.00823 L= 8.23 mL</em></u> (being 1 L= 1000 mL)

Finally, you will need 8.23 mL of the stock solution.

<h3>Concentration of the diluted solution</h3>

In this case, you know:

  • Ci= 7 M assuming the stock solution is 7.00 M HNO₃
  • Vi= 20 mL= 0.02 L
  • Cf= ?
  • Vf= 0.270 L

Replacing in the definition of dilution:

7 M× 0.02 L= Cf× 0.270 L

Solving:

(7 M× 0.02 L)÷ 0.270 L= Cf

<u><em>0.518 M= Cf</em></u>

Finally, the concentration is 0.518 M.
