The chlorination of the iron (III) ion is an endothermic reaction. Fe3+
(aq) + 2Cl(aq)
FeCl2 (aq)
Which change will cause the system to shift to the left and produce more Fe3+(aq)?

supongo que te refieres al paralaje estelar (observable).

si es así, entonces se puede inferir que la estrella está a más de 200 parsecs.

base : bases are those which donates ab electron-pairs.

alkali : it is a base that dissolves in water. it is basically a base and the ph greater than 7.

hydroxide ion : it is a poly-atomic ion which is negatively charged.

- lead + phosphoric acid = hydrogen + lead(ii) phosphate
