Concentration and ion moles are equal only when volume is what ?
Answers
Concentration and ion moles are equal only when volume is 1. Of 1.0 x 10-6 and 1.0 x 10-4, the larger number is 1.
The concentration of ions in a solution depends on the mole ratio. The molarity is the moles per solute upon the value of the solution. The official symbol of molarity is the concentration (c)
The concertation is the ratio or the amounts of solute per amount of solution. Molarity is the unit of concentration that relates to the number of moles solute per liter of solution. Molarity is moles of solute / 1Lt of solution. Moles are equal only when the volume is indirectly proportional to the solution.Learn more about the concentration and ion moles that are equal.

Which answer best describes the continental shelf?
75-mile shallow flat area just off coastlines
thick deposits of sediments carried out from land
the surf area along coastlines
area of land that drops toward deep ocean basins
Answers
The answer that best describes the continental shelf is thick deposits of sediments carried out from land. The correct option is b.
What is a continental shelf?Geologists refer to the portion of the continental margin between the shoreline and the shelf break—or. In the absence of a discernible slope, between the shoreline and the point where the depth of the adjacent water is roughly between 100 and 200 meters—as the "continental shelf."
Where the continental shelf stops, the continental slope starts. It serves as a dividing line between the oceanic and continental crusts, much as its name suggests.
The continental slope separates the crusts of the continents and the oceans. Gravity's effect causes soil, boulders, and debris to eventually wash down the steep sides of a continental slope over time. At the bottom of the slope, they amass into a clump.
Therefore, the correct option is b, thick deposits of sediments carried out from land.

When the speed of the bottle is 2 m/s, the KE is kg m2/s2. When the speed of the bottle is 3 m/s, the KE is kg m2/s2. When the speed of the bottle is 4 m/s, the KE is kg m2/s2. When the speed of the bottle is 5 m/s, the KE is kg m2/s2. When the speed of the bottle is 6 m/s, the KE is kg m2/s2.
instructions
In this part of the experiment, you will be changing the speed of the bottle by dropping it from different heights. You will use the same mass, 0.250 kg, for each trial, so record this mass in Table B for each velocity. Then, calculate the expected kinetic energy (KE) at each velocity. Use the formula KE = mv2,
where m is the mass and v is the speed. Record your calculations in Table B of your Student Guide.
Answers
Answer:
Based on the given instructions, you need to calculate the expected kinetic energy (KE) at each velocity using the formula KE = mv^2, where m is the mass and v is the speed. The mass is given as 0.250 kg.
Table B: Calculation of Kinetic Energy (KE)
Table B: Calculation of Kinetic Energy (KE)
Speed (m/s)Mass (kg)KE (kg m^2/s^2)20.2500.50030.2500.75040.2501.00050.2501.25060.2501.500
To calculate the kinetic energy at each velocity, multiply the mass (0.250 kg) by the square of the velocity.
For example, when the speed of the bottle is 2 m/s: KE = (0.250 kg) * (2 m/s)^2 = 0.250 kg * 4 m^2/s^2 = 1.000 kg m^2/s^2
Perform similar calculations for the other velocities and record the results in Table B.
Answer:
Explanation:mass of the bottle in each case is M = 0.250 kg
now as per given speeds we can use the formula of kinetic energy to find it
1) when speed is 2 m/s
kinetic energy is given as
2) when speed is 3 m/s
kinetic energy is given as
3) when speed is 4 m/s
kinetic energy is given as
4) when speed is 5 m/s
kinetic energy is given as
5) when speed is 6 m/s
kinetic energy is given as

1. Using D10W and a vial of NaCl 4 mEq/mL, how many mL of NaCl are needed to prepare 250 mL of a
D10/NS solution?
a. 4.8mL
b. 9.6ml
c. 19.6mL
d. 154mL
Answers
To prepare 250 mL of a D10/NS solution using D10W and a vial of NaCl 4 mEq/mL, you would need 9.6 mL of NaCl. Normal saline (NS) contains 154 mEq/L of sodium chloride (NaCl). To prepare 250 mL of NS, you would need 250 mL * (154 mEq/L) = 38500 mEq of NaCl. Since the vial of NaCl contains 4 mEq/mL, you would need 38500 mEq / (4 mEq/mL) = 9625 mL = 9.6 mL of NaCl. So the correct answer is b. 9.6ml.

How does the wavelength of a G-note sound wave compare to the wavelength of an A-note sound wave?

As frequency increases wavelength decreases and since the G note has a low frequency it will have a longer wavelength, and it’s the opposite for the A note- high frequency and short wavelength

When a chemical reaction does not occur, what happens to the atoms of the two substances? Provide an example from Sim as evidence to support your answer.
Answers
An example of this can be seen in the Sim on Amplify, where students can experiment with different chemical reactions. For instance, in the "Chemical Reactions" Sim, students can explore the reaction between iron and sulfur to form iron sulfide. In this reaction, the iron atoms and sulfur atoms combine to form a new compound, iron sulfide, with different properties than the original iron and sulfur. The atoms of the iron and sulfur are rearranged to form new bonds, resulting in the formation of a new substance. This is an example of a chemical reaction, where the atoms of the two substances are rearranged to form a new compound with different properties.

Explain why some gases are considered molecules but not compunds
Answers
Somes gases are considered molecules but not compounds because compounds are made up of atoms of different elements.
A molecule is made up of any two atoms together. A molecule consisting of atoms from various elements is referred to as a compound.
However, we can call all molecules compounds, but not all compounds molecules. Since hydrogen gas (H2) only contains one element, it is a molecule rather than a compound.
Two identical atoms can combine to form a molecule, as occurs when two oxygen atoms combine to form an oxygen molecule. All compounds, however, have two or more atoms of distinct kinds.
Example of molecules gases : Hydrogen gas (H2) Nitrogen gas (N2) Oxygen gas (O2) Chlorine gas (Cl2)
Example of compound gases : Ammonia NH3,
Methane CH4, Nitrous oxide N2O, Salt NaCl.

Answer: Every combination of atoms is a molecule. A compound is a molecule made of atoms from different elements. All compounds are molecules, but not all molecules are compounds. Hydrogen gas (H2) is a molecule, but not a compound because it is made of only one element.
Explaination: All compounds are molecules, but not all molecules are compounds. That is because a molecule can be made up of two atoms of the same kind, as when two oxygen atoms bind together to make an oxygen molecule. However, all compounds are made up of two or more different types of atoms.
