Question

Write out the balanced equation for the reaction that occurs when Mg(OH)2 and HCl react together. You do not need to make your subscripts smaller; just write them out as regular numbers. For example: Mg(OH)2.

Answer 1

Magnesium  hydroxide  react  with  hydrochloride  to  give  magnesium  chloride  and  water
  THe word  equation
  magnesium  hydroxide  +hydrochroric  acid---> Magnesium  chloride+water

chemical  equation
Mg(OH)2(S) +  2HCl (L)--> Mgcl2(S) + 2H2O(l)
when  balancing  the  equation  we  count  the  number  of  molecules  in  the  reactant  side   which  should  balance  with  molecules  in  the  product  side.

Answer 2

Answer: The balanced chemical equation is given below.

Explanation:

Mg(OH)2 is a base and HCl is an acid.

When a base reacts with an acid, it leads to the production of a salt with the release of water molecule. This reaction is known as neutralization reaction.

The balanced chemical equation for the reaction follows:

$Mg(OH)2+2HCl\rightarrow MgCl2+2H2O$

By Stoichiometry of the reaction:

1 mole of magnesium hydroxide reacts with 2 moles of hydrochloric acid to produce 2 moles of magnesium chloride and 2 moles of water molecule.
