Answer:
1 mole
Explanation:
m(Fe) = 112 g
n(Fe₂O₃) = ?
First you must calculate how many moles of Fe is in 112 g of Fe:
n(Fe) = m(Fe) / Ar(Fe) = 112 g / 55,85 g moles⁻¹ = 2 moles
Now, from reaction you compare moles of Fe and Fe₂O₃ :
2 n(Fe₂O₃) = n(Fe)
n(Fe₂O₃) = n(Fe) / 2 = 1 mole
Boiling point of
glucose = 150°C
AlCl3 = 180°C
NaCl = 1,413°C
CaCl2 = 1,935°C
Therefore, the one with the lowest boililng point is glucose
Its C
An ionic bonded compound as the bond is formed from a metal and a non metal plus its a strong electrostatic attraction between 2 or more elements

Answer:
The positive charges equal the negative charges, so the atom has no overall charge; it is electrically neutral. Most of an atom's mass is in its nucleus; the mass of an electron is only 1/1836 the mass of the lightest nucleus, that of hydrogen.
