a) AuBa + 2NO3
b) Au(NO3)2 + Ba
c) AuBa(NO3)2
d) Au(NO3) + Ba2

Answer 1

The correct balanced equation for the reaction between Au and Ba(NO3)2 is Au + Ba(NO3)2 → Au(NO3)2 + Ba.

Step-by-step explanation:

The correct balanced equation for the reaction between Au and Ba(NO3)2 is:

Au + Ba(NO3)2 → Au(NO3)2 + Ba

The reaction involves a single replacement reaction, where Au replaces Ba in the compound Ba(NO3)2 to form Au(NO3)2 and Ba. The chemical equation is balanced by ensuring that the number of atoms of each element is the same on both sides.
