Answer 1

In Roman Catholic teaching, the Sacrament of Penance(commonly called Confession, Reconciliation or Penance) is the sacrament given by Our Blessed Lord to the Church by which individual men and women may be freed from sins committed after Baptism.

In the Sacrament of Penance, the penitent must examine himself beforehand, confess ALL grave sins by kind and number to the priest (or bishop). He then must express contrition for his sins, and a firm purpose of amendment (not to do them again). He then receives Our Blessed Lord's absolution through His minister, the priest or bishop. After leaving the sacrament, he must perform his penance which was assigned to him by the priest. The contrition on the part of the penitent and the firm resolve not to do it again are both necessary for the absolution to be effective.
Penance or confession, historically adminstered as Sacrament no.2 in the order of application- Baptism(all) Confession ( All) Communion ( all) Confirmation (all) then the selective Episcopal sacraments ( which can only be conferred by a Bishop) -but confirmation is one , also- Holy Orders The Last Rites or Extreme Unction- for the dead and dying- and usually numbered lastly- Matrimony. Only a Bishop can conduct Confirmation and Ordination ceremonies. all of the others can be administered by a Priest.
They are the same thing. "Reconciliation" is the post-Vatican II term for the Sacrament of Penance.
