Answer:
Molecular equation is nothing but the balanced chemical equation with the physical states of substances shown which we find out using the solubility rules.
Group IA salts are soluble so [tex]Na_2CO_3[/tex] and NaCl are soluble in water hence (aq) is the physical state.
Chlorides are generally soluble except that of Ag, Pb amd Hg so [tex]AlCl_3[/tex] is soluble.
Carbonates are insoluble except that of Group IA and ammonium ion
hence [tex]Al_2(CO_3 )_3[/tex] is insoluble and the physical state is (s) which indicates insoluble solid or a precipitate
Insoluble solid precipitate (s), Liquid (l) and gas (g) do not produce ions.
Salts which are soluble in water (aq) produce ions which are shown in the ionic equation
Net ionic equation do not contain the common ions which are present on both the sides of the ionic equation and are called as spectator ions
Balancing is making the number of atoms of each element same on both the sides (reactant and product side).
To find the number of atoms of each element we multiply coefficient and the subscript
For example [tex]5Ca_1Cl_2[/tex] contains
5 ×1 = 5, Ca atoms and
5 × 2 =10, Cl atoms
If there is a bracket in the chemical formula
For example [tex]3Ca_3(P_1 O_4 )_2[/tex] we multiply coefficient × subscript × number outside the bracket to find the number of atoms (Please note: 3 is the coefficient, and if there is no number given then 1 will be the coefficient )
So
3 × 3 = 9 , Ca atoms
3 × 1 × 2 = 6, P atoms
3 × 4 × 2 = 24, O atoms are present.
Answer:
Molecular equation:
[tex]2AlCl_3 (aq)+3Na_2 CO_3 (aq)>Al_2(CO_3 )_3(s)+6NaCl(aq)[/tex]
Ionic Equation :
[tex]2Al^{3+}(aq)+6Cl^{1-}(aq)+6Na^{1+}(aq)+3CO_3^{2-}(aq)>1Al_2(CO_3 )_3 (s)+6Na^{1+}(aq)+6Cl^{1-}(aq)[/tex]
Net ionic equation :
[tex]2Al^{3+}(aq)+3CO_3^{2-}(aq)>1Al_2(CO_3 )_3 (s)[/tex]
Please note: [tex]Cl^-[/tex] and [tex]Na^+[/tex] are spectator ions
