Answer:
Molecules are made of atoms. atoms are smaller. molecules have no electrons, atoms do.
Answer:
well one of the begins with and A while the other one begins with a M, joking so the difference between an atom and a molecules is that, An atom is the smallest unit of matter that retains all of the chemical properties of an element. while Molecules can be described as the smallest particle of an element or a compound, which is capable to exist independently and shows all the properties of the respective substance. Hope this helps :)

Observe Record the appearance (colors,
textures, etc.) of the reactants in the data table.
How many reactants are there?
DONE
Answer:
1
Explanation:
By observing the appearance (colors, textures, etc.) of the reactants in the data one reactant is there.
What is reactant?A reactant is a substance or can say a chemical compound that is present at the start of a chemical reaction. The substance(s) to the right of the arrow are called products.
For example we take a reaction-
O₂(g) + H₂(g) → H₂O(g)
Here, O₂ and H₂ are the reactants and H₂O is the product.
A reactant is present 100% initially and after sometimes it reduces gradually to form product according to chemical kinetics.
Given, the picture shown and the colour and texture of the reactant is shown.
Therefore, By observing the appearance (colors, textures, etc.) of the reactants in the data one reactant is there.

Tanisha is mixing powdered orange drink mix into a cup. She wants to make sure the orange taste is strong, so she adds a lot of powdered mix. As she is mixing, she notices that the powdered mix starts to float around in the water in clumps, and some settles on the bottom of the cup. Predict why this would happen.
A.
The powder is too old to dissolve in the water.
B.
No more powder will dissolve in the water.
C.
The powder needs to be shaken to fully dissolve.
D.
The powder does not fully dissolve because the water is too warm.
Answer:
B. No more powder will dissolve in the water.
Explanation:
If a lot of powder is added to the water, then a fully saturated solution would be created. This means that no matter how much more powder is added or how strong the mix is shaken, no more powder will disolve. The powder will instead remain in solid form in the solution.
Answer:
Heat up the water first because it increases solubility of the powdered mix.

why is the symbol Ar used in the electron configuration of potassium, and what does it represent?
Answer:
It represents the noble gas that precedes the period before Potassium.
Explanation:
Period before potassium is 3, the noble gas in that period is Ar (Argon). So when condensing the electron configuration of Potassium, Argon can account for 18 electrons instead of writing out 18 electrons in full form from 1s2, 2s2 etc.
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.

Why does soap work to remove oil? (Note that most oils can be considered non-polar. A soap molecule has one end that is polar and one end that is non-polar.)
Answer:
Soap breaks up the oil into smaller drops, which can mix with the water.
Explanation:
This works because soap is made up of molecules with two different ends.
The soap molecules works as a surfactant for the water oil interphase. The hydrophobic head of the soap molecules trap the oil and dirt ad remove from the surface.
What are surfactants?Surfactants are chemical substances used to reduce the interfacial tension between substance boundary. Soaps and detergents acts as surfactants which are used to remove the dirt and oil from material surface.
Soap has both polar and non-polar characteristics. The alkaline part in the soap causes it to have a polar head, and because of the electric charge on this head, the soap is hydrophilic. A hydrophilic part of soap is drawn to water and will cling to it.
In this instance, the positive-charged hydrogen atoms of the water's hydrogen atoms match with the polar head of the soap molecule. The other part of soap is a fatty acid tail, which is hydrophobic and can bind with the oil and dirt. The trapped oil molecules are then be removed by water.
