Just need the ionic equations + net ionic equations for the problems.
#5 h of the experiments listed, use a small (grain I J For afthe liquid solutions. Feel free to add a little bit more to ensure the reactions tale pi assume that the solid is soluble for all of these reactions. 4Take a small amount of sodium carbonate and place it in a small test tube. Add a few drops of 1.0 M hydrochloric acid in the test tube and record your observations. olberurtons fizzingludoly uwflt neutral Names: goium hydrochloric Odumuter canone acid. - H20 Mol.

Complete ionic equation s include ions
Q1.
2Na+(aq) + CO3-2(aq) + 2H+(aq) +2Cl-(aq) --> 2Na+(aq) + 2Cl-(aq) + H2O(l) + CO2(g)
net ionic includes only reacting species
CO3-2(aq) + 2H+(aq) --> H2O(l) + CO2(g)
Q2
if no bubles present, then
2Na+(aq) + CO3-2(aq) + 2H+(aq) +2Cl-(aq) --> 2Na+(aq) + 2Cl-(aq) + H2CO3(aq)
the acid is formed, since it is molecular, then avoid ionic states
CO3-2(aq) + 2H+(aq) --> H2CO3(aq)
Q3
for acetic acid
2Na+(aq) + CO3-2(aq) + 2CH3COOH(aq) --> 2Na+(aq) + 2CH3COO-(aq) + H2O(l) + CO2(g)
net ionic
CO3-2(aq) + 2CH3COOH(aq) --> 2CH3COO-(aq) + H2O(l) + CO2(g)
the molecular acid + ionic acetate must be included
