The wavelength of a radio wave having a frequency is 0.8m.
Radio waves are the longest waves in the electromagnetic spectrum. These waves are a form of electromagnetic radiation with frequencies ranging from 300 GHz to 3 kHz, but above 3 GHz are defined as microwaves. Wave frequency is the number of waves passing through a fixed point in a given time.
calculation:-
frequency = 3.75 x 10^7 Hz?
f = wavelength / speed of light
wavelength = c/f
= 3 × 10^8 / 3.75 x 10^7 Hz
= 0.8 m.
Frequency is the rate at which the current changes direction per second. It is measured in hertz an international unit of measurement where one hertz equals one cycle per second. To calculate the frequency of a wave, divide the velocity of the wave by the wavelength. Write your answer in Hertz or Hz which is the unit for frequency. If you need to calculate the frequency from the time it takes to complete a wave cycle or T the frequency will be the inverse of the time or 1 divided by T.

find the volume of 0.250 m sulfuric acid necessary to react completely with 74.3 g sodium hydroxide.
The volume of 0.250 m sulfuric acid necessary to react completely with 74.3 g sodium hydroxide is 3.7 L.
The chemical reaction of sulfuric acid and sodium hydroxide is given as below:
H2SO4 + 2NaOH ------- Na2SO4 + 2H2O
From above, we noticed that, one mole of sulfuric acid react with two moles of sulfuric acid.
Therefore, firstly we convert grams of sulfuric acid into moles.
As we know that, molar mass of sodium hydroxide is 40 g.
What is mole?It is defined as the given mass to the molar mass of substance.
Mathematically,
Moles = Given mass / molar mass
Given mass of sulfuric acid = 74.3 g
By substituting all the values, we get
Moles = 74.3 / 40
= 1.85 mol
So, 1/2 moles of sulfuric acid one moles of sodium hydroxide.
Or, 1.85 moles of sodium hydroxide react with 1/2 × (1.85) moles of sulfuric acid.
1.85 moles of sodium hydroxide react with 0.925 moles of sulfuric acid.
Now,
Concentration of sulfuric acid = 0.250 M
Moles of sulfuric acid = 0.925 mol
C = m/ V
V = m/ C
= 0.925/ 0.250 = 3.7 L
Thus, we concluded that the volume of 0.250 m sulfuric acid necessary to react completely with 74.3 g sodium hydroxide is 3.7 L.

Affinity chromatography is a technique for extracting a biomolecule from a mixture that relies on a very particular macromolecular binding relationship between the biomolecule and another component. Depending on the biomolecule of interest, the specific type of binding contact may be between an antigen and an antibody, an enzyme and a substrate, a receptor and a ligand, or a protein and a nucleic acid. Binding interactions are routinely used to isolate different biomolecules. When compared to other chromatographic techniques, affinity chromatography is advantageous due to its high selectivity and resolution of separation.

Molar mass CO₂
= 12.0107 + 2 * 15.999
= 44.0087 g/mol
Moles CO₂ = 15.1 g / 44.0087 g/mol = 0.388559535 moles
We know we needed twice as much HCl based on the balanced equation,
so 0.388559535 mol * 2 = 0.77711907 mol
Simply divide the amount of moles by the number of liters because molarity is defined as moles per liter,
so: 0.77711907 mol / 0.625 l = 1.24339051 mol/l
Since our data only has three significant figures, round it to three figures to get 1.24 m.
