Here is what i got from my notes, hope this helps.
Mixture components keep their identities.
Mixture components CAN be separated PHYSICALLY
Homogenous Mixture: You CAN NOT the different parts (phases) of the mixture
Heterogeneous Mixture : You CAN SEE the different parts (phases) of the mixture easily
A solution is a HOMOGENOUS MIXTURE of particles so small that they cannot be seen and CANNOT be filtered out
A compound is something that is made from something that can be separated from 2 things.
It is a mixture and has chemical bonds.
The three broad classes of elements are:
Metals
Metalloids
Nonmetals
Answer:
When titanium (II) nitride forms an ionic compound, TiN is the chemical formula of the compound.
Answer:
Mg²⁺(aq) + SO₃²⁻(aq) + 2 H⁺(aq) + 2 I⁻(aq) ⇄ Mg²⁺(aq) + 2I⁻(aq) + H₂O(l) + SO₂(g)
Explanation:
<em>Give the complete ionic equation for the reaction (if any) that occurs when aqueous solutions of MgSO₃ and HI are mixed.</em>
When MgSO₃ reacts with HI they experience a double displacement reaction, in which the cations and anions of each compound are exchanged, forming H₂SO₃ and MgI₂. At the same time, H₂SO₃ tends to decompose to H₂O and SO₂. The complete molecular equation is:
MgSO₃(aq) + 2 HI(aq) ⇄ MgI₂(aq) + H₂O(l) + SO₂(g)
In the complete ionic equation, species with ionic bonds dissociate into ions.
Mg²⁺(aq) + SO₃²⁻(aq) + 2 H⁺(aq) + 2 I⁻(aq) ⇄ Mg²⁺(aq) + 2I⁻(aq) + H₂O(l) + SO₂(g)
