When you mix soap with water, you are diluting it unto less strong soap.
When you use soap and water mixed togehter to wash your hands, you are using the chemical propertiies of the soap to your advantage. The soap is made of hundreds of thousands of tiny strands that have a "water loving" end and a "oil loving" end. The oil loving ends attach to the oil on your skin, and the water loving ends stick out. This is called a micelle. Thousnds of micelles form and are ready to be rinsed away, with the oil that was on your skin inside of them. We need soap insted of just water because oil does not mix with water, and therfore cannot just be rinsed off with it.

Answer: The correct answer is Option B.
Explanation:
To calculate the number of moles, we use the formula:
Molar mass of iron = 55.8 g/mol
Given mass of iron = 558.8
Putting values in above equation, we get:
For the given chemical equation:
By Stoichiometry,
4 moles of Iron produces 2 moles of Iron(III) oxide
So, 1 mole of Ion will produce = 
= 0.5 mole of Iron (III) oxide.
Hence, the correct answer is Option B.
Answer:
Visible light
Explanation:
our eyes are sensitive to a very narrow band of frequencies within the enormous range of frequencies of the electromagnetic spectrum. This narrow band of frequencies is referred to as the visible light spectrum. Visible light.
Compound is a pure substance where atoms of two or more elements are chemically bonded togather
In the context of multivalent ions, it is when it has multiple oxidative states.
