Hello! I am sure the second one has the lowest because of how little it is moving unlike 1,3,and 4 maybe this helps, Have a great day!

<h2>Hello!</h2>

The wave with the lowest frequency is the second one.

<h2>Why?</h2>

Frequency is defined as the number of times that a periodic phenomenon is repeated in a given time. Regarding waves, the frequency of a wave is the number of times that a wave repeats in a unit of time. Frequency is measured in Hertz (Hz=1/s).

The relationship between frequency and wavelength is inverse, meaning that longer wavelengths mean lower frequencies. From the given list, the wave with the longest wavelength is the second one, meaning that its frequency is the lower.

Have a nice day!

What volume of water is needed for 0.196 mol of CdCl2 to prepare a 3.91 M solution? L
Brilliant_brown [7]

0.050 litres of the water will be required to make a 3.91 M solution with 0.196 moles in it.

Explanation:

Data given:

moles of CdCl_{2} = 0.196 Moles

Molarity of the solution = 3.91 M

Volume in litres =?

molarity is calculated by the formula:

molarity = \frac{number of moles}{volume in litres}

putting the values in the above formula and rearranging it for volume:

volume = \frac{number of moles}{molarity}

volume = \frac{0.196}{3.91}

volume = 0.050 litres

0.050 litres of the water will be required to make a 3.91 M solution with 0.196 moles in it.

Molarity is the number of moles present in a given volume of solution which is given in litres. It is the measurement of the concentration of particular solute in a solution.

12. If the total pressure exerted by 3 gases is 45 atm and each individual gas has the
Bumek [7]

Answer:

Partial pressure for each of the three gases, in the mixture is 15 atm

Explanation:

Remember that the total pressure of a mixture, is the sum of partial pressures from the gases contained in the mixture.

Our total pressure = 45 atm

The 3 gases have the same pressure, so we can propose this equation:

3x = 45 atm

where x is the partial pressure for each of the three gases.

x = 45/3 → 15 atm

Describe how an acidic solution forms when HCHIS
kakasveta [241]
The presence of H3O+ is the hydronium ion, and one definition of an acid is something that donates a proton (H+). HCl in this case does just that. Basic solution forming with NaOH and water: ... NaOH + H2O ==>Na+ + OH- so it donates or produces OH- ions, thus making a basic solution
