Answer: This chemical reaction is a neutralization reaction between the Milk of Magnesia and the HCl from the stomach. The balanced equation is Mg(OH)2 (s) + 2 HCl (aq) → MgCl2 (aq) + 2 H2O (l)
Explanation:
The reaction between the HCl and the Mg(OH)2 is a neutralizacion reaction , because the HCl is a strong acid and the Mg(OH)2 is a weak base, then both react and the pH of the medium will increase, so the stomach trouble will dissapear.
Mg(OH)2 (s) + 2 HCl (aq) → MgCl2 (aq) + 2 H2O (l)
Magnesium hydroxide is a weak base due to its very limited solubility in water. This property is a great advantage when treating the excess of HCl in the stomach, because the Mg(OH)2 molecule does not dissociated easily until it reacts with the hydrogen ion, H+ of the HCl. So the effect of the Mg(OH)2 will last longer until the annoyance dissapear.
Answer:
evaporates
Explanation:
the heat from the sun causes it to evaporate
Answer : The 
for the reaction is, 54.89 KJ
Solution : Given,
Mass of ZnS = 48.7 g
Molar mass of ZnS = 97.474 g/mole
First we have to calculate the moles of ZnS.
The balanced combustion reaction is,
From the given reaction, we conclude that
As, 2 moles of ZnS gives energy = 220 KJ
So, 0.499 moles of ZnS gives energy = 
Therefore, the for the reaction is, 54.89 KJ
