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)

1 bar or 1000 mbar = 750 mm Hg
0.931 bar = 931 mbar = 698.3 mm Hg.</span>
The Question is incomplete here is the complete question " Suppose an iron atom in the oxidation state +3 formed a complex with three hydroxide anions and three water molecules. Write the chemical formula of this complex.
Answer:
{Fe(OH)3(H20)3}
Explanation:
Oxidation state is the electron gained or lost by and atom, So if iron is in +3 state in formula it must have lost three electron.
We know that OH posses the oxidation state of -1 and water have zero oxidation state. SO, Let's take iron equal to y and find its oxidation state in the formula
y + 3 ( - 1 ) + 3 ( 0 ) = 0
y - 3 + 0 = 0
y-3=0
y= + 3
Hence it's proved that iron has +3 oxygen state.
A physical change is a change to a sample of matter in which some properties of the material change, but the identity of the matter does not. Physical changes can further be classified as reversible or irreversible. The melted ice cube may be refrozen, so melting is a reversible physical change.
