Liquid antacids contain suspensions of bases like aluminum hydroxide and magnesium hydroxide. These are usually the bases that can neutralize the stomach acids.
The chemical equation representing the neutralization reaction of stomach acid, HCl and antacid, aluminum hydroxide: Three moles of hydrochloric acid reacts with one mole aluminum hydroxide to give the salt, aluminum chloride and three moles of water.
Answer: Special care is required to prepare a solution of sodium hydroxide or NaOH in water because considerable heat is liberated by the exothermic reaction. The solution may splatter or boil. Here is how to make a sodium hydroxide solution safely, along with recipes for several common concentrations of NaOH solution.
Explanation:
Hope this helps!
So mass of sulphur
Moles =64/32=2
So
So tons of sulphur dioxide
Answer:
The correct answer is <em>c. Distillation</em>
Explanation:
The volatility of a substance refers to the tendency to vaporize. The more volatility, more readily the substance vaporizes and passes from liquid state to gas state.
From the options, the only operation that separes substances by their tendency to vaporize is distillation. In distillation, evaporation and condensation processes at different temperatures are used to separe miscible liquid substances.
Therefore, the correct option is c. Distillation
