1. Predict the products (including physical states), and write the total ionic and net ionic equations for the reaction between hydrochloric acid and aqueous sodium hydroxide. chemical equation total onic equation net ionic equation: 2. Predict the products (including physical states), and write the total ionic and net ionic equations for the reaction between magnesium metal and hydrochloric acid. balanced chemical equation total ionic equation net ionic equation 3. a) What change of state does "heat of fusion" apply to? b) Write an equation with states of matter included to indicate this physical change. c) Is this physical change exothermic or endothermic? d) The heat of fusion for H2O is 6.01 kJ/mol. Convert value to units of J/g (show work) J/gExplanation / Answer
1) balanced chemical equation: In this just wtite down the reactants and products as a whole and then balanced it.
HCl (aq) + NaOH (aq) - - - - - - - > NaCl(aq) + H2O(l)
Total ionic equation : write equation in terms of ions
Na+ + OH- + H+ + Cl- - - - - - > Na+ (aq) + Cl- (aq) +
H2O(l)
Net ionic equation : As we can Na+ and Cl- cancel out each other in total ionic equation, so net ionic equation would be,
H+ (aq) + OH-(aq) - - - - - - - > H2O (l)
2) Similarly proceeds for this one
Balanced chemical equation :
Mg(s) + 2HCl - - - - - - - > MgCl2 + H2(g)
Total ionic equation :
Mg(s) + 2H+(aq) + 2Cl- (aq) - - - - - > Mg2+(aq) + 2Cl- (aq) + H2(g)
Net ionic equation :
Mg(s) + 2H+ (aq) - - - - - - > Mg2+(aq) + H2(g)
