Question

Mg(OH)2+HCL gives mgcl2+ h2o balance it

Answer 1

HEY THERE...
-------------------------------------------
The balanced equation is

Mg(OH)2 + 2HCl -----------> MgCl2 + 2H2O

The above balancing means 1 mole of magnesium hydroxide when reacted with 2 mole of hydrochloric acid, yields 1 mole of salt i.e. magnesium chloride and 2 moles of water.
