‘2’AgNO3 + Cu -> Cu(NO3)2 + ‘2’Ag
The statement that is NOT a part
of John Dalton's atomic theory Electrons move in specific orbits around the
nucleus of an atom. The statements ‘All elements are composed of atoms that
cannot be divided’, ‘All atoms of the same element are exactly alike and have
the same mass’ and ‘Every compound is composed of atoms of different elements,
combined in a specific ratio’ are not his theory.
Each molecule of Sr₃(PO₄)₂ contains 3 moles of Sr
So 3 moles of Sr⁺² ions are in one mole of Sr₃(PO₄)₂.
Solid= Connected and Concentrated and Bound Together.
Liquid= Not bound but free flowing, less concentrated.
Gas= Spaced out and not concentrated, floating freely through space.
