Which chemical equation represents the reaction of an arrhenius acid and an arrhenius base?
(1) hc2h3o2(aq) + naoh(aq) --> nac2h3o2(aq) + h2o(l)
(2) c3h8(g) + 5 o2(> 3 co2(g) + 4 h2o(l)
(3) zn(s) + 2 hcl(> zncl2(aq) + h2(g)
(4) bacl2(aq) + na2so4(aq) --> baso4(s) + 2 nacl(aq)

Suppose you got a low yield of benzoin from your benzoin condensation reaction and thus only have 0.300 g of benzoin to use as the starting material for this reaction. how much concentrated nitric acid should you add? (concentrated nitric acid is 15.8 m). write your answer in the form x.xx ml

An empty fuel tank can still contain and therefore can be even more dangerous than one full of liquid fuel.
