magnesium hydroxide Mg(OH)2 is an antacid that is used to relieve indigestion, sour stomach and hurtburn. it can be prepared by reacting magnesium chloride, MgCL2 and sodium hydroxide, NaOH with the by-product of sodium chlrodie, Nacl. in an experiment, a student allowed 15.1g of MgCL2 to react with 9.35 g NaOH. Calculate the mass in grams of Mg(OH)2 that could be obtained at the end of the experiment.

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.
