Write a balanced equation for the dissociation of Mg(NO3)2. I wrote Mg(NO3)^2(s)==>Mg^2+(aq)+NO3^3-(aq)
That isn't the answer in the book. Can someone explain to me how dissociation works?
I would have written just as you did but 2NO3^-(aq). The equation you wrote isn't balanced. If the answer in the book is different, perhaps we can point out the problem if you post the answer. Also, the book may have wanted H2O in there as in Mg(NO3)2(s) + H2O ==> Mg(2^+(aq) + 2NO3^-(aq)
Sure, I'd be happy to explain! Dissociation is a process in which a compound breaks apart into its constituent ions when dissolved in water. In the case of Mg(NO3)2, it dissociates into magnesium ions (Mg^2+) and nitrate ions (NO3^-).
The balanced equation for the dissociation of Mg(NO3)2 is:
Mg(NO3)2(s) -> Mg^2+(aq) + 2NO3^-(aq)
In this equation, the solid state of Mg(NO3)2 (s) indicates that it is in the solid form before dissolving in water. The (aq) represents the species being in the aqueous or dissolved form in water.
So, when Mg(NO3)2(s) dissolves in water, it separates into Mg^2+ ions and two NO3^- ions. Each NO3^- ion has a -1 charge, so two of them are needed to balance the charge on the Mg^2+ ion, which has a +2 charge.
I hope this explanation helps! If you have any more chemistry questions, feel free to ask, and I'll do my best to answer with a touch of humor!
Dissociation refers to the process in which a compound breaks apart into its constituent ions when it is dissolved in water. Let's break down the steps to balance the equation for the dissociation of Mg(NO3)2.
Step 1: Identify the compound
The compound, Mg(NO3)2, consists of one magnesium ion (Mg2+) and two nitrate ions (NO3-) combined together.
Step 2: Determine the products
When Mg(NO3)2 dissolves in water, it breaks apart into its constituent ions: Mg2+ and two NO3- ions.
Step 3: Write the balanced equation
Based on the information from Step 2, the balanced equation for the dissociation of Mg(NO3)2 is:
Mg(NO3)2 (s) --> Mg2+ (aq) + 2NO3- (aq)
Note: The (s) indicates that Mg(NO3)2 is in the solid state, while (aq) signifies that the ions are in an aqueous (dissolved) state.
It's worth mentioning that the formula for the nitrate ion, NO3-, should have a superscript of (-)1 rather than (-)3 as you wrote in your original equation.
Sure! Dissociation refers to the process in which an ionic compound breaks apart into its constituent ions when it is dissolved in a solvent, such as water. In the case of Mg(NO3)2, it dissociates into magnesium ions (Mg^2+) and nitrate ions (NO3^-).
To write a balanced equation for the dissociation of Mg(NO3)2, we need to ensure that the equation obeys the law of conservation of mass and charge. Here's how you can do it:
Step 1: Write the formula for the compound:
Mg(NO3)2
Step 2: Identify the ions that make up the compound:
Mg^2+ and (NO3)^-
Step 3: Indicate the dissociation of the compound into its constituent ions:
Mg(NO3)2(s) ⟶ Mg^2+(aq) + 2NO3^-(aq)
In this balanced equation, the solid Mg(NO3)2 dissociates into one Mg^2+ cation and two NO3^- anions in the aqueous form. The coefficient "2" in front of NO3^- ensures that the same number of nitrate ions are present on both sides of the equation.
Remember that the correct answer may vary depending on the context or specific instructions given, so it's always a good idea to double-check with your book or instructor.
