Thagt it has lost three electrons.
Aluminium metal has 13 protons(+) and 13 electrons(-), as the neutrally charged atom.
However, as the aluminium cation it has 13 protons(+) and 10 electrons(-) in the charged ion.
(+)13 (-) 10 = (+)3
Hence its ionic charge is Al^(3+).
AlCl3+ 3NaOH = Al(OH)3+ 3NaCl
The plus symbol, "+", is used to indicate an addition.
3 plus 3 plus 3 is 9. 3 plus 3 plus 3 plus 3 plus 3 plus 3 is 18.
The answer to your question is twenty four.
15
The oxidation half-reaction is: 3Ag --> 3Ag^+ + 3e^-
The chemical equation is:2 Al +3 CuCl2 = 3 Cu + 2 AlCl3
Trimethyl aluminium is not a solid precipitate.
AlCl3+ 3NaOH = Al(OH)3+ 3NaCl
Mn2O7+Al=
The balanced equation is Al(OH)3 + 3HCl ==> 3H2O + AlCl3
Yes, aluminum (Al) is paramagnetic because it has unpaired electrons, which causes it to be weakly attracted to a magnetic field.
the answer is 2 apex
Three electrons are gained when going from Al to Al3+ because aluminum typically loses 3 electrons to become stable in its 3+ ion state.
The plus symbol, "+", is used to indicate an addition.
The balanced equation is: 2Al(s) + 3Zn(NO3)2(aq) -> 2Al(NO3)3(aq) + 3Zn(s)
27x3+6=87.
