2. Enter the net ionic equation, including phases, for the reaction of AgNO3(aq) and KCl(aq).
3. Consider this aqueous reaction: HNO3(aq) + Ba(OH)2(aq)>>>>>>>What is the formula for the salt that forms?
4. If a new halogen were discovered with the name sapline and the symbol Sa, how would the following acids of sapline be named?
a. HSa__________acid
b. HSaO__________acid
c. HSaO2__________acid
d. HSaO3__________acid
e. HSaO4__________acid
Explanation / Answer
1. Given the reaction
Pb(NO3)2(aq) + K2CO3(aq) -----> PbCO3(s) + 2KNO3(aq)
the net ionic equation for the above reaction is
Pb2+(aq) + 2NO3-(aq) + 2K+(aq) + CO32-(aq) ------> Pb2+9s) + CO32-(s) + 2K+(aq) +2NO3-(aq)
the equation can be written as
Pb2+(aq) + 2NO3-(aq) + 2K+(aq) + CO32-(aq) -----> PbCO3(s) + 2KNO3(aq)
2. given the reaction is
AgNO3(aq) and KCl(aq)
the balanced equation is
AgNO3(aq) + KCl(aq) ------> AgCl(s) + KNO3(aq)
the net ionic equation is
Ag+(aq) + NO3-(aq) + K+(aq) + Cl-(aq) -----> Ag+(s) + Cl(s) + K+(aq) + NO3-(aq)
the equation can be written as
Ag+(aq) + NO3-(aq) + K+(aq) + Cl-(aq) -----> AgCl(s) + KNO3(aq)
3. given the reaction
HNO3(aq) + Ba(OH)2(aq)
the balanced equation is
HNO3(aq) + Ba(OH)2(aq) -----> Ba(NO3)2(s) + H2O(l)
H+(aq) + NO3-(aq) + Ba2+(aq) + 2OH-(aq) ----> Ba2+ + 2NO3- + H+ + OH-
H+(aq) + NO3-(aq) + Ba2+(aq) + 2OH-(aq) -----> Ba(NO3)2 + H2O
4. given that if a new halogen was discovered with the name sapline and with the symbol Sa..
then the names for the compounds given in the question are as follows
a.HSa : Hydrosaplic acid or hydrogen saplide
b. HSaO : Hyposaplous acid
c. HSaO2 : saplous acid
d. HSaO3 : saplic acid
e. HSaO4 : Perchloric acid
