Answer:
is equal to the total number of products
Explanation:
it forms :
1. Gold ( Au )
2. Zinc nitrate ( Zn(NO3)2 )
When a chunk of zinc is added to a solution of gold (III) nitrate to extract the gold. The reaction forms Gold and Zinc nitrate .
it's a single displacement reaction,
here's the balanced equation for above reaction :
3 Zn + 2 Au(NO3)3 =》3 Zn(NO3)2 + 2 Au
