Given:
2 Mg + O2 → 2 MgO
So,
<span>(25.0 g of Mg / 24.3051 g/mole) x (1/2) x (22.4 L/mole) = 11.5 L of Oxygen will react with 25 grams of magnesium metal.</span>
Ionic bonds are a metal and a non metal bond and a covalent bond is two no metals banded together.
Answer:
It does not dissolve readily.
Explanation:
Answer:
Ca(OH)2 --> Ca2+ + 2OH-
Explanation:
Calcium hydroxide is sparingly soluble in water. It dissociates to give the following:
The net ionic equation :
Ca(OH)2 + H2O --> Ca2+ + 2OH- + H2O
Since, H2O doesn't affect the overall reaction, therefore;
Ca(OH)2 --> Ca2+ + 2OH
