Answer: it is coastline.
Explanation: This anwser would only makw sense because of the low elevation and the flat land.
The landform shared by Florida and the eastern border of South Carolina is the coastline. Option C is the correct answer.
Both states are located along the Atlantic Ocean and have a similar geographical feature characterized by flat land and low elevation along their eastern borders. Option C is the correct answer.
The coastline refers to the area where the land meets the sea. It is typically marked by sandy beaches, coastal marshes, and barrier islands. In the case of Florida and the eastern border of South Carolina, this coastline is known for its relatively flat terrain and low elevation, which makes it susceptible to flooding and storm surge during hurricanes. The coastline plays a significant role in the economies and ecosystems of both states. It attracts tourism and provides opportunities for recreational activities such as beachgoing, fishing, and boating. It is also a vital habitat for various marine and coastal species, including birds, turtles, and marine mammals.

Explanation:
Determine the empirical formula of a compound containing 48.38 grams of carbon, 8.12 grams of hydrogen, and 53.5 grams of oxygen
As with most stoichiometry problems, it is necessary to work in moles. The ratio of the moles of each element will provide the ratio of the atoms of each element.
Get the mass of each element by assuming a certain overall mass for the sample (100 g is a good mass to assume when working with percentages).
Remeber that percentages are a ratio multiplied by 100. You must convert percentages back to their decimal value before working with them.
(.4838) (100 g) = 48.38 g C
(.0812 ) (100 g) = 8.12 g H
(.5350) (100 g) = 53.38 g O
Convert the mass of each element to moles of each element using the atomic masses.
(48.38 g C) (1 mol/ 12.10 g C) = 4.028 mol C
(8.12 g H) (1 mol/ 1.008 g H) = 8.056 mol H
(53.38 g O) (1 mol/ 16.00 g O) = 3.336 mol O
Find the ratio or the moles of each element by dividing the number of moles of each by the smallest number of moles.
Use the mole ratio to write the empirical formula.

Calculate the pH of the following aqueous solution:
0.35 M NaF (pKa for HF = 3.14)
I'm pretty sure I know how to calculate the pH by itself, but I am confused on how to get the equation. I'm not sure what HF has to do with this, other than it's an acid. I'm probably overthinking it because it's worded differently. Thanks in advance!
The pH of an aqueous solution that has a concentration of 0.35 M NaF and pKa for HF = 3.14 is 3.6.
How to calculate pH?The pH of a solution refers to the degree of acidity or alkalinity of the solution. It can be calculated using the Henderson-Hasselbalch Equation as follows:
pH = pka + log ([A-]/[HA])
Where;
A- = conjugate baseHA = weak acidpH = pKa + log([F-]/[HF])
pH = 3.14 + log(1/0.35)
pH = 3.14 + 0.4559 = 3.595
Therefore, the pH of an aqueous solution that has a concentration of 0.35 M NaF and pKa for HF = 3.14 is 3.6.

a 21.0 kg rock rests on the edge of a cliff 32.0 m high. how much gravitational potential energy does the rock have
Explanation:
Formula for Potential energy=mgh mass* gravity*height
21kg × 10 ×32=6720joules
If a 21.0 kg rock rests on the edge of a cliff 32.0 m high, the gravitational potential energy gained by the rock would be 6585.6 Joules.
What is mechanical energy?Mechanical energy is the combination of all the energy in motion represented by total kinetic energy and the total stored energy in the system which is represented by total potential energy.
As given in the problem a 21.0 kg rock rests on the edge of a cliff 32.0 m high, then we have to calculate the potential energy gained by the rock,
The potential energy of the rock = 21 × 9.8 × 32
= 6585.6 Joules.
Thus ,If a 21.0 kg rock rests on the edge of a cliff 32.0 m high, the gravitational potential energy gained by the rock would be 6585.6 Joules.

What is the equilibrium constant K at 25°C for an electrochemical cell when E° = +0.0140 V and n = 2?(F = 96,500 J/(V･mol), R = 8.314 J/(mol･K))
The equilibrium constant of the electriochmeical cell as shown is 2.976.
What is the equilibrium constant?The equilibrium constant of a reaction shows the extent of the conversion of the reactants to products.
Now we know that;
ΔG = -nFE°cell
n = 2
F = 96,500 J/(V･mol)
E°cell = +0.0140 V
ΔG = -(2 * 96,500 * 0.0140)
ΔG = -2702 J
But;
ΔG = -RTlnK
lnK = -(ΔG/RT)
K = e^[-(ΔG/RT))
K = e^[-(( -2702)/8.314 * 298]
K = 2.976

calculate, a can of chicken broth contains 450 mg of sodium chloride in 240.0g of broth. What is the percent by mass of sodium chloride in the broth?
Answer:
The percent by mass of sodium chloride in the broth is 0.1875 %
Explanation:
Our first step is transforming the sodium chloride figure from mg to g
450mg x 1g/1000 mg= 0.45g
Now, we must calculate the percentage by using the following formula:
0.45g / 240g x 100= 0.1875%
Henceforth, we can conclude that the percentage by mass of sodium chloride in the broth is 0.1875%
The per cent by mass of sodium chloride in the broth is 0.1875 %
What is per cent by mass?The mass per cent of a component of a compound is the percentage ratio of the mass of the component by the total mass of the compound. The formula is mass per cent = (mass of component / total mass of compound) × 100.
Given data:
Mass of sodium chloride =450 mg = 0.45g
Now, we must calculate the percentage by using the following formula:
[tex]\frac{0.45gX 100}{240g }[/tex]
= 0.1875%
Hence, we can conclude that the percentage by mass of sodium chloride in the broth is 0.1875%

You are provided with powdered samples of the metals and common laboratory apparatus.
Answer:
Measuring electode potential
Explanation:
Make an electrode of all of them and measure standard reductive potential metals with lower srp will be more reactive
The metals which are placed above the hydrogen in the reactivty series can produce hydrogen gas with HCl. The order of reactivity of given metals is as follows: Zinc > iron > tin.
What is reactivity series?The reactivity series of elements or the activity series can be defined as the arrangement of metals in descending order according to their reactivities.
The metals placed at the top of the activity series are strong reducing agents and can be readily oxidized. These metals readily tarnish/corrode. The reducing ability becomes weaker while moving down the reactivity series.
The electropositivity of the elements decreases as we move down in the reactivity series of metals. All metals which are placed above hydrogen in the activity series can able to release hydrogen gas upon reacting with dilute HCl.
Therefore, the metals Iron, tin, and zinc release hydrogen gas when they react with the HCl. The order of reactivity is according to their reduction potential which is Zinc > iron > tin.
