2al(c2h3o2)3 + 3baso4 → al2(so4)3 + 3ba(c2h3o2)2 which type of chemical reaction does this equation represent? f synthesis g neutralization h oxidation-reduction j double-replacement

Answer is: j. double-replacement.
Double displacement reactions - cations and anions of the two reactants switch places and form two new compounds.
Neutralizationis is reaction in which an acid and a base react quantitatively with each other. In this reaction, there are no acids and bases, only salts.
Synthesis is reaction of two or more substances combining to make a more complex substance. In this example, there is more complex substance in products.
Oxidation-reduction reactions - change in the oxidation number between the reactants and the products. In this example there is no change in oxidation number of elements.

And a) oxygen i believe

Man i dont know this answer
