Specifically critique your personal impact on the changing climate.
Answer:
We can no longer ignore the fact that the world's climate is becoming more unpredictable and more extreme. As water levels rise, the risk of flooding looms large. At the same time, periods of drought are becoming longer and more frequent. Yet, our most precious resource – our planet's biosphere – is not only under threat. It is also the source of many of our solutions. Green Climate Solutions is the Wageningen Environmental Research programme that applies our understanding of nature and natural processes to address the challenges of climate change.

Explain why a) Kl (potassium iodide) dissolves in water, but b) it will not dissolve in
hexane.
Answer:
Explanation: Brief description of demonstration
Three clear liquids form three distinct layers in a cylinder. Iodine crystals sprinkled on the top layer sink and form pink solutions with the top and bottom layers but do not dissolve in the middle. When the liquids are mixed, two layers form: a pink layer on the bottom, and a colorless layer on top. When white potassium iodide crystals are added and the liquids are mixed again, the colorless layer turns yellow.
Concepts illustrated:
• Phases and phase boundaries (surfaces)
• Density
• Polar/non-polar (hydrophilic/hydrophobic) interactions
• Solubility, miscibility
• Chemical reaction
• Extraction
• [Solution and emulsion]
Materials
• Clear glass reaction cylinder or gas-washing bottle, at least 200 mm tall, with ground glass stopper (A cylindrical container is preferable to a separatory funnel for this experiment. The stopper must be non- reactive, and, to prevent a potentially dangerous pressure build-up, the stopper must be easily released. For a very small class, a large test tube with a suitable stopper is adequate. )
• Equal volumes of chloroform, water, and hexane (The volume of each liquid should be a little more than one-fourth the volume of the cylinder.)
• Iodine crystals and small spatula
• Potassium iodide crystals and medium spatula
Preparation
Work in a hood. Pour the chloroform into the reaction cylinder. Add the water and allow the liquids to separate completely. (If necessary, speed the process by holding the cylinder vertical and gently swirling the solution with a circular motion.) Tip the cylinder and pour the hexane slowly down the side to prevent mixing. Close the cylinder and set it aside, away from sources of heat, until time for the demonstration.
Answer:It forms single phase mixtures (solutions) with other polar and ionic substances. ... Since water is less dense than this non-polar mixture, the bubbles rise to the top. Potassium iodide, an ionic compound, dissolves easily in water but does not dissolve in chloroform and hexane.
Explanation:
If the ball is at rest on the soccer field and the four forces shown are applied at the same time, the ball will
А.
move to the left.
B. stay in the same position.
c. accelerate in the direction of the smallest force.
D. resist any change in movement.
Since the rightward force is greater than the leftward force by a magnitude of 10 Newton, the ball will: A. move to the left.
Given the following data:
Upward force = 50 Newton.Downward force = 50 Newton.Rightward force = 30 Newton.Leftward force = 40 Newton.A net force can be defined as the vector sum of all the forces acting on an object.
Hence, net force is the sum of all forces acting simultaneously on an object.
To determine the direction in which the ball would move if the four forces shown are applied at the same time:
For the downward and upward force:
[tex]Net\;force = 50-50\\\\Net\;force = 0\;Newton[/tex]
For the rightward and leftward force:
[tex]Net\;force = 40-30\\\\Net\;force = 10\;Newton[/tex]
Since the rightward force is greater than the leftward force by a magnitude of 10 Newton, the ball will move to the left.

PLZ FASTLEY ANSWER The images show two metamorphic rock samples.
Left: light colored rock with coarse texture. Right: red and white rock with rounded grains and coarse texture.
Which statement accurately describes these rocks?
Both rocks are non-foliated.
Neither rock has randomly arranged grains.
Both rocks formed at Earth’s surface.
Neither rock formed through extreme heat or pressure.
Answer:
a
Explanation:
From the given images, it is clear that both rocks are non-foliated rocks because they don't have distinct repetitive layers. Hence option a is correct.
What are metamorphic rocks?Metamorphic rocks are formed through intense pressure and heating from the sedimentary or igneous rocks. Sometime the change n heat or pressure make the metamorphic rocks gets foliated.
Foliation occurs when pressure forces flat or elongate minerals within a rock to align. These rocks form a platy or sheet-like structure that reflects the pressure direction. There is no platy or sheet-like structure in non-foliated metamorphic rocks.
Non-foliated rocks can be created in a variety of ways. Some rocks, like limestone, are composed of minerals that are not flat or elongate. Therefore, the given rocks are non-foliated.

If you had a 100 mL of a solution of 0.01 M NaF, how many moles would that solution contain?
Answer:
0.001 mole of NaF.
Explanation:
From the question given above, the following data were obtained:
Volume of solution = 100 mL
Molarity = 0.01 M
Mole of NaF =?
Next, we shall convert 100 mL to litre (L). This can be obtained as follow:
1000 mL = 1 L
Therefore,
100 mL = 100 mL × 1 L / 1000 ml
100 mL = 0.1 L
Thus, 100 mL is equivalent to 0.1 L.
Finally, we shall determine the number of mole of NaF present in the solution. This can be obtained as follow:
Volume of solution = 0.1 L
Molarity = 0.01 M
Mole of NaF =?
Molarity =mole /Volume
0.01 = mole of NaF / 0.1
Cross multiply
Mole of NaF = 0.01 × 0.1
Mole of NaF = 0.001 mole.
Thus, 0.001 mole of NaF is present in 100 mL of the solution.

The question is incomplete, the complete question is;
AlBr3 can be used as a catalyst in the Friedel-Crafts alkylation reaction. The correct name for the compound represented by the formula AlBr3 is —
aluminum bromide
monoaluminum tribromide
aluminide bromine
aluminum tribromide
Answer:
aluminum bromide
Explanation:
Having known that AlBr3 is an ionic compound and aluminium is the central atom here, we now have to ask ourselves if Aluminium exists in other stable oxidation states.
We must take cognizance of the fact that the oxidation number of the central atom in a compound becomes part of the name of that compound when other stable oxidation states for atoms of the same elements exists.
Since the +3 state is the only stable oxidation state for aluminium, the name of the compound is simply aluminium bromide.
