Answer:

The lower the radiant energy, the lower the frequency and the longer the wavelength.

Explanation:

Definition of Radiant Energy: The energy transmitted by an electromagnetic wave.

Definition of Electromagnetic Spectrum: The entire range of the electromagnetic radiation, from the longest wavelengths to the shortest.

Definition of Frequency: The number of waves per second.

Definition of Wavelength: The length of a wave.

Longer wavelengths result in smaller, lower frequencies.

Shorter wavelengths result in larger, higher frequencies.

Energy is directly proportional to frequency and energy inversely proportional to wavelength. Wavelength is inversely proportional to frequency.

Making solutions is an extremely important component to real-life chemistry. If you make 3.00 L of a solution using 90.0 g of so

kumpel [21]

Answer:

Final concentration of NaOH = 0.75 M

Explanation:

For $NaOH$ :-

Given mass = 90.0 g

Molar mass of NaOH = 39.997 g/mol

The formula for the calculation of moles is shown below:

$moles = \frac{Mass\ taken}{Molar\ mass}$

Thus,

$Moles= \frac{90.0\ g}{39.997\ g/mol}$

$Moles\ of\ NaOH= 2.2502\ mol$

Molarity is defined as the number of moles present in one liter of the solution. It is basically the ratio of the moles of the solute to the liters of the solution.

The expression for the molarity, according to its definition is shown below as:

$Molarity=\frac{Moles\ of\ solute}{Volume\ of\ the\ solution}$

Where, Volume must be in Liter.

It is denoted by M.

Given, Volume = 3.00 L

So,

$Molarity=\frac{2.2502\ mol}{3.00\ L}=0.75\ M$

Final concentration of NaOH = 0.75 M

Electrons hold a negative charge, and anion refers to a negatively charged atom.

The answer is anion. Here's a way to help remember:
