How does vegetation slow and prevent sediment loss?

Answers

Answer 1
Answer: Vegetation cover is the most effective and practical way to prevent loss of sediment. The roots of vegetation such as grass bind soil particles together to resist erosion especially from runoff water. Vegetation helps absorb the impact of raindrops to prevent detachment of soil particles. Vegetation can flatten act like shingles on a roof, which allows the runoff to flow above the soil.Stiff standing vegetation act as a wind break, reducing wind velocity, such that it is not powerful enough to dislodge sediments from the ground surface.
Answer 2
Answer:

Final answer:

Vegetation slows and prevents sediment loss in rivers and streams by binding the soil together and slowing down the flow of water. Shade from plants also helps reduce phytoplankton growth.

Explanation:

Vegetation plays a crucial role in slowing and preventing sediment loss in rivers and streams. The roots of plants help bind the soil together, reducing erosion caused by the force of water. As water flows through vegetation, it is slowed down, allowing sediment to settle out. Additionally, plants provide shade, which helps keep the water temperature lower, creating an environment less suitable for phytoplankton growth.

An emission Ray has a frequency of 5.10 x10^14 Hz. Given that the speed of light is 2.998 x10^8 m/s, what is the wavelength of the Ray?

Answers

Speed of Light = frequency × wavelength
                     C = λ ν
               ∴ ν =  C ÷ λ
                  ν = (2.998 * 10^(8) m/s )  ÷  (5.10 * 10^(14) Hz)
                     =  5.87 × 10 ^(-7) m

1. The following reaction does not proceed to form a product: H2O + Au---> no reaction. Why is that?A) Gold has a higher activity than hydrogen and cannot replace it.
B) Gold has a lower activity than hydrogen and cannot replace it.
C) The reaction cannot occur because water is a reactant.
D) The reaction proceeds too slowly to create products.

5. If ions change places and a gas is formed, then what type of reaction is indicated?

A) double-displacement
B) synthesis
C) decomposition
D) single-displacement

Answers

1. B
The positive charge in water is provided by hydrogen, and gold provides the same charge. However, gold is not more reactive than hydrogen so it can not replace it in the compound.

2. In order to balance the equation, you must sure there are equal moles of each element on the left and right side of the equation:
2C₂H₆ + 7O₂ → 4CO₂ + ₆H₂O

3. The number of moles of sodium atoms on the left of the equation must be equal to the number of moles of sodium atoms on the right, as per the law of conservation of mass. The answer is B.

4. C.
A synthesis reaction usually results from single displacement because some element or compound is produced in its pure form

5. B. 
The gas being produced is being synthesized.

How many mol of hydrogen in 2.6 mol of caffein

Answers

The chemical formula of caffeine is C8H10N4O2. Caffeine is only a common name but using IUPAC, it is given the nomenclature 1,3,7-Trimethylpurine-2,6-dione. 1 mole caffeine has 10 moles of hydrogen (as shown in the chemical formula) hence, 2.6 moles caffeine has 26 moles of hydrogen. 

The escape of molecules from the surface of a liquid is known as _____.A. Sublimation
B. Condensation
C. Evaporation
D. Boiling

Answers

The escape of molecules from the surface of a liquid is known as \boxed{{\text{C}}{\text{. Evaporation}}}.

Further Explanation:

Phase transition is defined as the change from one state to another state but no change in chemical composition is observed. It is also known as a phase change, state change or physical change.

Sublimation

It is the process by which a substance directly gets converted from solid to vapor phase, without going through the liquid state. Naphthalene and dry ice are substances that undergo sublimation.

Condensation

It is the phase transition that occurs when vapors are converted into liquid. This is done by changing the temperature and pressure of the substance.

Evaporation

In this process, liquid changes into vapors. Here, temperature has to be elevated or heating is done. Energy is used up in the substance and therefore it is an endothermic process.

Boiling

It is a phase change in which liquid is converted to a gaseous state when liquid is heated to its boiling point.
