The frequency of a wave can be calculated using the wavelength and and speed of light. The frequency of a wave with 225 nm is 1.33 × 10¹⁵ Hz.
<h3>What is frequency ?</h3>
Frequency of a wave is the number of wave cycles per second. It mathematically taken as the inverse of time taken to travel and it have a unit of s⁻¹ other than Hz.
The wavelength of an electromagnetic wave is the distance between two consecutive crests or troughs.Wavelength and frequency are in inverse relationship. For a longer wavelength the frequency will be lower.
Higher frequency waves are more energetic than longer wavelengths. Thus energy and frequency are in direct proportion
It is given that the wavelength of the electron is 225 nm. Consider the electron behaving as wave and the frequency v can be calculated using the speed of light c as follows:
= (3 ×10⁸ m/s) /(225 ×⁻⁹ m)
= 1.33 × 10¹⁵ Hz.
Hence, the frequency of an electron with a wavelength of 225 nm is 1.33 × 10¹⁵ Hz.

Aq means it's soluble in H2O by default
s means it's solid, not soluble.
Answer:
Approximately .
Explanation:
The gallium here is likely to be produced from a solution using electrolysis. However, the problem did not provide a chemical equation for that process. How many electrons will it take to produce one mole of gallium?
Note the Roman Numeral "" next to . This numeral indicates that the oxidation state of the gallium in this solution is equal to . In other words, each gallium atom is three electrons short from being neutral. It would take three electrons to reduce one of these atoms to its neutral, metallic state in the form of .
As a result, it would take three moles of electrons to deposit one mole of gallium atoms from this gallium solution.
How many electrons are supplied? Start by finding the charge on all the electrons in the unit coulomb. Make sure all values are in their standard units.

Calculate the number of electrons in moles using the Faraday's constant. This constant gives the size of the charge (in coulombs) on each mole of electrons.
.
It takes three moles of electrons to deposit one mole of gallium atoms . As a result, of electrons would deposit of gallium atoms .
Answer:
A. Contain cells that connect to form pipes.
B. Transport water and food.
Explanation:
The vascular tissue is known to be conducting tissue which has more than one cell type. It is usually found in vascular plants. It is composed of xylem and phloem.
Their function is to transport fluid (like water) and other nutrients, therefore they have cells that connect to form pipes. The xylem and phloem occur together in vascular bundles in the plant organs passing through stems, leaves and roots.
