    can you help me with these two3. In a double-replacement reaction, the _____. (1 point) products are always molecular reactants are two ionic compounds reactants are two elements products are a new element and a new compound 4. Which of the following is a balanced equation representing the decomposition of lead(IV) oxide? (1 point) PbO2 Pb + 2O PbO2 Pb + O2 Pb2O 2Pb + O PbO Pb + O2

    General form for a double replacement reaction (salt metathesis reaction): A-B + C-D → A-D + C-B So what would you guess?

    Okay I can say it is not D. A example of a double replacement reaction could be BaCl2(aq) + NaSO4 (aq) -> NaCl (aq) + BaSO4 (s)

    OK here we go: "Double displacement: This is when the anions and cations of two different molecules switch places, forming two entirely different compounds."

    A or B can't fully say, can't find any clear 100% fool proof place in my book that say it is true
