Answer:
As this sheet of water moves on and off the beach, it can “capture” and transport beach sediment back out to sea. This process, known as “longshore drift,” can cause significant beach erosion.
The one that will dissolve most quickly is : D. a tablespoon of ultrafine sugar
Unlike any other type of sugar, ultrafine sugar tend to have smaller crystal size. Which means that this substance will dissolve easier if it put into liquid such as tea or water
hope this helps
Given:
K = 0.71 = Kp
The reaction of sulphur with oxygen is
S(s) + O2(g) ---> SO2(g)
initial Pressure 6.90 0
Change -x +x
Equilibrium 6.90-x x
Kp = pSO2 / pO2 = 0.71 = x / (6.90-x)
4.899 - 0.71x = x
4.899 = 1.71x
x = 2.86 atm = pressure of SO2 formed
temperature = 950 C = 950 + 273.15 K = 1223.15 K
Volume = 50 L
Let us calculate moles of SO2 formed using ideal gas equation as
PV = nRT
R = gas constant = 0.0821 L atm / mol K
putting other values
n = PV / RT = 2.86 X 50 / 1223.15 X 0.0821 = 1.42 moles
Moles of Sulphur required = 1.42 moles
Mass of sulphur required or consumed = moles X atomic mass of sulphur
mass of S = 1.42 X 32 = 45.57 grams or 0.04557 Kg of sulphur
Based on ecological studies, the definitions below applies to the given terms:
- Peak phenomena: this is when a population grows at a fast rate, then quickly drops when the resources run out
- Biological surplus: this occurs when there are more organisms in a population than the ecosystem can sustain
- Climax community: this is a point in an ecosystem when all populations reach a point of little or no change
- Sigmoid phenomena: this is when a population increases while food and habitat are abundant and decreases as food becomes less available
<h3>What is ecology and what are some terms in ecology?</h3>
Ecology is the study of living things and their interactions with their environment.
Some terms in ecology include:
- Peak phenomena: this is when a population grows at a fast rate, then quickly drops when the resources run out
- Biological surplus: this occurs when there are more organisms in a population than the ecosystem can sustain
- Climax community: this is a point in an ecosystem when all populations reach a point of little or no change
- Sigmoid phenomena: this is when a population increases while food and habitat are abundant and decreases as food becomes less available
