Answer:
C. Runoff from heavy rainfall forms narrow, shallow channels.
Explanation:
Erosion is the gradual washing away of the top layer of the soil or earth on which plant grows. There are three main types of erosion which are:
1. Sheet erosion
2. Gully erosion
3. Rill erosion
Rill erosion occurs when a soil layer is gradually being washed away by narrow stream channels called streamlets on the surface. After a heavy downpour, the streamlets facilitates the movement of water on the ground surface and in turn, earth materials are worn away.
When these streamlets becomes deeper, they form gullies. Gullies results into gully erosion.
When runoff removes soil and loose sediment in thin layers it is called sheet erosion.
Answer:
4g/mol
Explanation:
Firstly, we can get the number of moles of the gas present using the ideal gas equation.
PV = nRT
Here:
P = 886 torr
V = 224ml = 224/1000 = 0.224L
T = 55 degrees celcius= 55+ 273.15 = 328.15K
R = molar gas constant = 62.36 L⋅Torr⋅K−1⋅mol−1
n = PV/RT
n = (886 * 0.224)/(62.36 * 328.15)
n = 0.009698469964 mole
Now to get the molar mass, this is mathematically equal to the mass divided by the number of moles. We have the mass and the number of moles, remaining only the molar mass.
First, we convert the mass to g and that is 38.8/1000 = 0.0388
The molar mass is thus 0.0388/0.009698469964 = 4g/mol
Answer:
<h3>The answer is 286.36 cm³</h3>
Explanation:
In order to find the volume be at 101.3 kPa we use Boyle's law which is
where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume
Since we are finding the final volume
From the question
P1 = 112 kPa = 112000 Pa
V1 = 259 cm³
P2 = 101.3 kPa = 101300 Pa
We have
We have the final answer as
<h3>286.36 cm³</h3>
