    the chemical equation for the combustion of HCL and NH3 is as follows.NH3 + HCl -----> NH4Cl.the product formed is amoonium chloride. NaOH ----> Na+ + OH The answer is "yes; HCl will dissociate in water". The simple explanation for this process is because HCl is aqueous.The trick is to write the information given by the balanced equation (Eq. Info.) above the equation and the information provided by the problem (Prob. Info.) below the equation. Write the information above and below the participant identified in the equation by the problem, ignoring those participants not required for the solution of the problem.

Silica alcosol was synthesized by keeping the molar ratio of ethyltriethoxysilane (ETES) precursor, ethanol (EtOH) solvent, water (H2O) was kept constant at 1:36:6.6 respectively, with 6 M NH4OH throughout the experiment and the percentages of hydrophobic agent in hexane bath was varied from 0 to 15 vol.%. Solubility and Net Ionic Equations. Net ionic equations are useful in that they show only those chemical species participating in a chemical reaction. The key to being able to write net ionic equations is the ability to recognize monoatomic and polyatomic ions, and the solubility rules. Example #1: Suppose we had 1.00 mole of sucrose (its mass is about 342.3 grams) and proceeded to mix it into some water. It would dissolve and make sugar water. We keep adding water, dissolving and stirring until all the solid was gone. We then made sure that when everything was well-mixed, there was exactly 1.00 liter of solution. 6.25 The equation as written shows that 879 kJ of heat is released when two moles of ZnS react.
