And mass of HNO3 taken = 75.0, Q:A student is provided with an unknown solution, which will contain one of the follow cations: Ba?, A:Mixing of Cation in NaCl, NaOH & Na2SO4 solution and forms Ppt. The volume of Cd2+ = 0.550 L (a) Write the balanced net ionic equation for the reaction between Mg (s) and HCl (aq). Indicate if the reaction does, Q:AIs questioL Tlas lmuiti All you have is a mixture of Mg2+ , Cl- , NO3- and H+ ions. Enter an ionic equation (solubility states are optional) to calculate its complete and net ionic equations. Second, we write the states and break the soluble ionic compounds into their ions (these are the strong electrolytes with an (aq) after them). Write the remaining substances as the net ionic equation.Writing and balancing net ionic equations is an important skill in chemistry and is essential for understanding solubility, electrochemistry, and focusing on the substances and ions involved in the chemical reaction and ignoring those that dont (the spectator ions).More chemistry help at http://www.Breslyn.org Write the state (s, l, g, aq) for each substance.3. a H+(aq) + OH(aq) H2O(l) b H+(aq) + KOH(aq) K+(aq) + H2O(l) c HF(aq) + KOH(aq) K+(aq) + F(aq) d HF(aq) + K(aq) + OH(aq) KF(aq) + H2O(l) e HF(aq) + OH(aq) F(aq) + H2O(l). The student collects the H2(g) produced by the reaction and measures its volume over water at 298 K after carefully equalizing the water levels inside and outside the gas-collection tube.
