When you are told it is a single replacement reaction, that is telling you how to write the products, IF a reaction occurs. A single replacement means the single material, since it is a metal, will replace the positive ion in the "other" molecule. But that happens only if the metal is ABOVE the ion in the activity series.
Al + H2SO4 ==> Al2(SO4)3 + H2. Note the Al ion replaces H^+ since Al is above H in the activity series. I'll let you look us Au and K for the first one.
Au(s) +
Write a balanced chemical equation for each single replacement reaction.
A) Au(s) + KNO3(aq) ==> ???
B) Al(s) + H2SO4(aq) ==> ???

I didn't balance it.
