Wind and Erosion lead to Washing away of top soil.
What Is Erosion?Erosion is the process that lead to the washing away of top soil leading to loss of nutrient, holes and many more.
The agents of erosion include wind, water and so on.
Strong wind will lead to the top soil to be remove when it is blowing. Water also when is is flowing turbulently maybe when rain fall can lead to loss of top soil.
Therefore, Wind and Erosion lead to Washing away of top soil.

Determine the percent yield for the reaction between 98.7 g of
Sb2S3 and excess oxygen gas if 72.4 g of Sb4O6 is recovered along with an unknown amount of sulfur dioxide.
The percent yield of the reaction would be 85.64%
Percent YieldFrom the balanced equation of the reaction:
[tex]9 O_2 + 2 Sb_2S_3 ---> 6 SO_2 + Sb_4O_6[/tex]
Mole ratio of Sb2S3 to Sb4O6 is 2:1
Mole of 98.7g Sb2S3 = 98.7/339.7
= 0.29 moles
Equivalent mole of Sb4O6 = 0.29/2
= 0.145 moles
Mass of 0.145 Sb4O6 = 0.145 x 583
= 84.535 g
Percent yield = yield/theoretical yield x 100
= 72.4/84.535 x 100
= 85.64%

why is respiration considered an exothermic process
Answer:
Respiration is considered as exothermic reaction because energy is released in this process. Glucose combines with oxygen present in our cells to form carbon dioxide and water along with energy.
Explanation:
Good Luck!
Respiration is considered as an exothermic reaction because, in the respiration process, oxidation of glucose takes place which produces a large amount of heat energy stored in the form of ATP. This is shown in the following chemical equation C 6
Describe the motion of water molecules in a wave.
Lesson 2.13
Question 5 options:
Water molecules move up and forward, down and back, in an overall circular motion.
All of the choices
none of the choices
Water molecules don't move
Answer:
Molecules in the water move in a circular motion
Explanation:
Because of its circular motion it causes the waves to look like open circles which makes it easy for people to surf on
Water molecules move up and forward, down and back, in an overall circular motion in the wave. Therefore, option A is correct.
What is circular motion ?Circular motion is defined as the movement of an object while rotating in a circle. Circular motion can be uniform or asymmetric.
The angular rate of rotation and speed are constant in uniform circular motion, but the rate of rotation changes in non-uniform circular motion.
This means that circular motion can occur only if there is a "center seeking" force present; otherwise, things will travel in a straight line.
Within the wave, the water molecules move in a circular motion. Each water particle moves in a complete circle during a single wave period. The circle traced by a water particle on the ocean surface as a wave passes a given point has a diameter equal to the height of the wave.
Thus, option A is correct.

Which of the following processes is involved in the formation of sedimentary rocks?
O metamorphism
O cooling
O subduction
O deposition
Answer:
deposition
Explanation:
A carrier *
Organism that transmits disease through blood
O Person or animal that is infected with the disease but is asymptomatic
O Used to treat a bacterial infection, cannot be used to prevent an infection
Used to prevent a viral infection, must be given before the person is infected
Answer: carrier, is a person or other organism that has inherited a recessive allele for a genetic trait or mutation but usually does not display that trait or show symptoms of the disease. Carriers are, however, able to pass the allele onto their offspring, who may then express the genetic trait.

Explanation:
The carbon cycle plays an important in maintaining carbon balance on the earth.
What is the carbon cycle?The carbon cycle is the cycle by which carbon is recycled between the atmosphere and the geosphere.
In the carbon cycle, the process of recycling carbon do not include deep burial, compaction, and cementation.
Volcanic eruptions are one natural way that carbon can move OUT of the geosphere.
Fossil fuels, atmosphere, land biomass and rocks are all carbon reservoirs, but fossil fuels contains the MOST carbon.
The atmosphere is the carbon reservoir that changes the quickest and has the biggest direct effect on climate.
Ocean acidification occurs because the ocean absorbs more human-produced CO2, causing the acidity to increase.
A potential impact of ocean acidification is that ocean ecosystems may suffer, making it harder for humans to get food from the ocean.
Therefore, the carbon cycle is important in maintaining carbon balance on the earth.

Answer:
shift to restore equilibrium
Explanation:
Le Châtelier's Principle states that when a stress is applied to a system at equilibrium, the system will respond by shifting in the direction (either towards the products or reactants side) that opposes/ minimizes the effect of the stress.
Note that although the system tries to restore equilibrium, this equilibrium is a new equilibrium.
Equilibrium is the state of a reversible reaction when:
• two opposing reactions occur at the same rate;
• the concentrations of reactants and products are constant

Which has the larger change hydration in each pair of a)Na+ Or cs+ b)Sr+2 or Rb+ c)Na+ or Cl- d) O-2 or F- e)OH- or SH-
Answer:
See explanation
Explanation:
The size of the hydration enthalpy of a system depends on the attraction between the ions and the water molecules. Stronger attractions exist between water and smaller ions. The smaller the ion, the higher the hydration enthalpy is.
In the first pair, Na+ is smaller than Cs+ hence Na+ has a larger change in hydration enthalpy.
In the second pair, Sr2+ is smaller than Rb+ hence Sr2+ has a larger change in hydration enthalpy.
In the third pair, Na+ is smaller than Cl- hence Na+ has a larger change in hydration energy.
F- is smaller than O2- hence F- has a larger change in hydration energy.
OH- is smaller than the SH- hence the OH- has a larger change in hydration energy.

How many moles of NaNO, would you need to make 500 mL of a 2.5 M
solution of NaNO?
Answer:
1.25 moles NaNO
Explanation:
Molarity = moles/Volume (L)
moles = Molarity (M) x Volume (L)
M = 2.5 M
V = 500 mL = 0.5L
moles = M x V = 2.5 x 0.5 = 1.25 moles

(102 900 ÷ 12) + (170 × 1.27) = 8800
Step 1. Evaluate the expressions inside the parentheses (PEMDAS)
102 900 ÷ 12 = 8575
170 × 1.27 = 215.9
In multiplication and division problems, your answer can have no more significant figures than the number with the fewest significant figures.
Thus, the underlined digits are not significant, but we keep them in our calculator to avoid roundoff error.
Step 2. Do the addition (PEMDAS).
8575
+ 215.9
= 8790.9
Everything that you add to an insignificant digit gives an insignificant digit as an answer.
Thus, the underlined digits are not significant.
We must drop them and round up the answer to 8800.
