When HCl reacts with water, the hydrogen ions react with the hydroxide ions to form water: Hâº + OHâ» â HâO. Thus, the reaction between HCl and Mg(OH)â is then: 2HCl(aq) + Mg(OH)â(s) â MgClâ(aq) + 2HâO(l) The products are magnesium chloride and water. Using ions, the reaction is: 2Hâº(aq) + 2Clâ»(aq) + Mg(OH)â(s) â 2HâO(l) + MgÂ²âº(aq) + 2Clâ»(aq) We can cancel Clâ» from each side of the equation.
Nature of Data. The term data is broadly defined as a recorded observation of sensory input; thus data are empirical, that is events perceived by the senses.The following terms refer to distinctions that are commonly made with regard to data: 1  qualitative vs. quantitative. 2  discrete vs. continuous.ature of Data.
