The geologic process that directly forms beaches on the shores of the bay should be considered as the sediment deposition.
What is sediment deposition?The Deposition refer to the laying down of sediment that should be carried by wind, where the water should be flowing down or there is the sea or ice. Sediment could be transported just like the pebbles, sand ,and mud, or as salts mix in the water.
Therefore, The geologic process that directly forms beaches on the shores of the bay should be considered as the sediment deposition.

Based on the information in the table, which two elements are most likely in the same group, and why?
Determine whether each melting point observation corresponds to a pure sample of a single compound or to an impure sample with multiple compounds.
The question is incomplete, the complete question is;
Determine whether each melting point observation corresponds to a pure sample of a single compound or to an impure sample with multiple compounds.
Experimental melting point is BELOW literature value
Experimental melting point is CLOSE to literature value
WIDE melting point range
NARROW melting point range
Answer:
narrow melting point-pure sample of a single compound
experimental melting point is close to literature value-pure sample of a single compound
wide melting point range-impure sample of multiple compounds
experimental melting point is below literature value-impure sample of multiple compounds
Explanation:
The experimental melting point of a pure single compound is sharp and extremely close to the melting point of the substance as recorded in the literature. Usually, a pure substance melts within a narrow range of temperatures.
Impure samples of multiple compounds melt over a range of temperatures. Also if the experimental melting point is well below the record in literature, then the sample is contaminated by other compounds.

Transitions help the reader understand how the ideas in the argument are connected best explains why you should use transitions when writing an argument. Therefore, option C is correct.
Why is it important to use transitions?They are cues that assist the reader in understanding your ideas. Transitional words or phrases help you move your thoughts from one sentence to the next and from one paragraph to the next.
Finally, transitional words smoothly connect sentences and paragraphs so that there are no abrupt jumps or breaks between ideas.
They make a direct link between ideas, sentences, and paragraphs. Specific words are used in effective transitions. Avoid using pronouns such as "this" to refer to an entire concept because it is not always clear who or what "this" refers to.

Explanation:
How many grams of lithium chloride, molecular mass 42.5, are dissolved in water to make 500 mL of a 0.450 M solution?
A) 9.56g
B) 42.50g
C)21.25g
D)47.22g
Answer:
9.5625 gram
Explanation:
Molarity = mass in gram ÷ molar mass × volume in dm3
Mass in gram = molarity× molar mass × volume of solution in dm3
Mass in gram = 0.450×42.5×0.5=9.5625 g
how many moles are in 100.0 g of gold?
Answer:
196.96655
Explanation:
The answer is 196.96655. I assume you are converting between grams Gold and mole. The molecular formula for Gold is Au. The SI base unit for the amount of substance is the mole.
The quantity present in an atom or molecules of a given substance is called moles it is written as mol and is calculated with the help of molar mass and mass of the given substance.
0.507699 mol is present in the 100 gm of gold.
Moles of gold can be calculated by:Given,
Mass (m) = 100 gmThe atomic weight of Au (M) = 196.967The formula for calculating moles is:
[tex]\rm Moles (n) = \dfrac{Mass}{Molar \;mass}[/tex]
Substituting values in the formula:
[tex]\begin{aligned}\rm n & = \dfrac{100}{196.967}\\\\ & = 0.507699 \;\rm mol\\\\& = 0.5077\;\rm mol\end{aligned}[/tex]

which description shows copper at rtp?
a) stationary and closed together
b) stationary and randomly arranged
c)vibrating and in a regular arrangement
d) vibrating and in a random arrangement
Answer:
c)vibrating and in a regular arrangement
Explanation:
Copper is a chemical element represented by the symbol Cu and having atomic number 29. Copper is a transition metal which means its subshells are not completely filled and that is why they are vibrating in the room temperature. But copper is a solid at room temperature with regular arrangement of atoms.
Hence, the correct answer is "c)vibrating and in a regular arrangement".
