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.

Information. Information is processed data. The data that can be made useful is known as information. Information is basically the data plus the meaning of what the data was collected for. Data does not depend upon information but information depends upon data. It cannot be generated without the help of data.
