Answer:
Word that comes from a Greek word
Explanation:
Glucose is a natural monosaccharide, which has the following molecular formula: C6H12O6
From the chemical point of view, this molecule is a hexose (this is, it has 6 carbon atoms) and an aldose (since it has an aldehyde group)
Glucose as a word has its origin from the Greek word “gleukos”, which means “sweet wine”, and the suffix “ose”, which is used to for a sugar
French people then adapted this word (in order to define a new chemical word, to differentiate the type of sugar found in grapes, slight different from sugar found in other elements such as honey)

Hey there!
Chemical changes are changes in object's chemical compounds and chemical compositions, and often can't be reversed.
Here's an example:
If you have a piece of paper and you happen to burn it, that can't be reversed.
In other words, it can't be "un-burned". Nothing can restore it to its previous state.
Hopefully this helped!
1.81 x 10²⁴particles of Fe
Explanation:
Given parameters:
Number of moles = 3moles
Unknown:
Number of particles = ?
Solution:
The number of particles in a substance can be deduced from the relationship of number of moles with the Avogadro's number.
A mole of a substance is the quantity of substance that contains the Avogadro's number of particles.
1 mole = 6.02 x 10²³ particles
3 moles = 3 x 6.02 x 10²³ = 1.81 x 10²⁴particles of Fe

The ksp = 4.87 × 10^-17
Therefore; 4.87 ×10^-17 = [Fe2+][OH-]^2 = (X)(2X)^2 = 4X^3
Hence;
4x^3 =4.87 × 10^-17
x = 2.30 × 10^-6 M
therefore the molarity is 2.3 ×10^-6 M
Thus;
The mass of Fe(OH)2 in 100 ml of water, will be given by:
= 2.30 × 10^-6 mol/L = 2.3 ×× 10^-5 mole/100 mL
= 89.86 g/mol × 2.3 × 10^-6 × 0.100 = 2.07 × 10^-5 g
= 2.07 × 10^-5 g
= 2.07 × 10^-5 g
