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
The answer is "Option B"
Formula:
Na atoms= Na atoms moles \times NA
The three ways that an atom can fulfill this goal is to give away electrons, take an electron, and share electrons.
