Ireally need with this chem question. can anybody answer it with an explanation for the answer? .
which is the correct net ionic equation for the following reaction:
2hi (aq) + ca (oh)2 (aq) arrow cai2 (aq) + h2o (l)?
a.) h+ (aq) + ca+2 (aq) + 2 i− (aq) arrow cai2 (aq)
b.)ca+2 (aq) + 2 oh− (aq) to ca(oh)2 (aq)
c.)h+ (aq) + oh− (aq) to h2o (l)
d.)2hi (aq) + ca (oh)2 (aq) to cai2 (aq) + h2o (l)

C. Because you eliminate "spectator ions" or ions that are repeated and you can only do that to aqueous. So, Ca +2 and 2I -1 are the only ones you can remove for net ionic.

Of course: ) what’s your name ?

Answer is: the equilibrium  shifts toward the reactants, to the left side of chemical reaction.it is because lead(ii) nitrate dissociates in water: pb(no₃)₂ → pb²⁺(aq) + 2no₃⁻(aq).according to lechatelier's principle, the position of equilibrium moves to counteract thechange (more lead cations, common ion), the position of equilibrium will move so that the concentration ofproducts decrease and concentration of reactants of chemical reaction increase.read more on -
