Which is the correct formula for the compound made when aqueous solutions containing a dissolved magnesium compound and a dissolved chloride compound are mixed?

The correct formula for the compound made when aqueous solutions containing a dissolved Magnesium and Chloride are mixed is Magnesium chloride

Explanation:

If we suppose the existence of two components in aqueous solutions containing Magnesium and Chloride. For example: Hydrochloric acid - HCl and Magnesium hydroxide - .

The global reaction would be:  

HCl + --> +

It means, Hydrochloric acid is neutralized with Magnesium hydroxide to produce Magnesium chloride and Water.  

Besides of that, we can analyze the aqueos solution of every componenent:

For Hydrochloric acid:

HCl + --> +

For Magnesium hydroxide

+   --> +

Finally, the ionic compounds will form the salt:

+ ->  

i dont know

explanation:

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.
