Answer:
A mixture has more than one things that are not fused chemically
Explanation:
Mixture comprises two or three compounds that aren't fused chemically. They have no physical interactions. A solution contains two substances that are chemically mixed to form a new compound. The chemical properties of each substances are retained without change.
Answer:
deep blue solution of tetramminecopper [Cu(NH3)4]2+ complex ion.
Explanation:
For that you have to use the Aufbau principle
For example, writing the electronic configuration of Fe(28)
I recommend that you memorize the aufbau principle. Once you learn it, you don’t need anything else except the atomic number of the element to write it’s electronic configuration.
<span>Solid lithium oxide, the basic anhydride of lithium hydroxide reacts with water to make lithium ions and hydroxide ions.
Li2O(s) + H2O(l) --> 2LiOH(aq) ...... molecular equation
Li2O(s) + H2O(l) --> 2Li+ + 2OH- ..... ionic equation, and net ionic equation
BUT!!!!! The decomposition of potassium chlorate into KCl and O2 gas does not take place in aqueous solution. The equation should be.
2KClO3(s) --> 2KCl(s) + 3O2(g)
No ionic equation. There is nothing in solution.
This reaction does not occur in aqueous solution.
2Na(s) + I2(g) --> 2NaI(s)
No ionic equation. There is nothing in solution.
Clearly, to have an ionic equation there must be ions, and to have ions the salts have to be dissolved in water.</span>
