<span>An element is made of only one kind of atom, while a compound contains the atoms of two or more elements. For example, gold is made of only one kind of atom, so it is an element, but water is a mix of hydrogen and oxygen, so it is a compound.</span>
Answer:
long range order
Explanation:
A crystal consists of atoms, ions or molecules having both short range and long range order. The atoms, ions or molecules are arranged in a regular pattern throughout the lattice both at immediate vicinities and across the entire crystal structure.
This order accounts for the definite shape and unique properties of crystals which include their sharp melting and boiling points which distinguishes them from amorphous substances.
The amount of fat will affect its melting point
Answer:
Explanation:
Chemical equation:
HCl + Fe₂O₃ → FeCl₃ + H₂O
Balanced Chemical equation:
6HCl (aq)+ Fe₂O₃(s) → 2FeCl₃(aq) + 3H₂O(l)
Ionic equation:
6H⁺(aq) + 6Cl⁻(aq) + 2Fe⁺³(aq) + 3O²⁻(aq) → 2Fe⁺³(aq) + 6Cl⁻(aq) + 3H₂O(l)
Net ionic equation:
6H⁺(aq) + 3O²⁻(aq) → 3H₂O(l)
The Cl⁻(aq) and Fe⁺³(aq) are spectator ions that's why these are not written in net ionic equation. The water can not be splitted into ions because it is present in liquid form.
Spectator ions:
These ions are same in both side of chemical reaction. These ions are cancel out. Their presence can not effect the equilibrium of reaction that's why these ions are omitted in net ionic equation.
