Consider the following reaction: Ba(s) + F2(g) · --- - ---> BaF2. Which of the following statements is true? Select one: O a. The barium atom is losing electrons; therefore, it is oxidized. O b. The fluorine atom is losing electrons; therefore, it is reduced. O c. The barium atom is gaining electrons; therefore, it is oxidized. O d. The fluorine atom is gaining electrons; therefore, it is oxidized.

Identify the substances that are oxidized and reduced in each of the following reactions: a. Mg(s) + 2H*(aq) → b. 2Al(s) + 3Br.(g) Mg (aq) + H2(g) 2AIBT:(s)

Lead in the water pipe surface have two oxidation states (as PbO and PbO₂). PbO can transform into dissolved species in the drinking water, so that a strong oxidizing agent (free chlorine, Cl₂) is used to prevent this process by further oxidizing PbO into the non-soluble species, PbO₂. Balance the net chemical reaction below. Show your process. PbO + Cl₂ + H₂O PbO₂ + H + CI™
