When the equation below is balanced using the smallest whole number coefficients, what is the sum of all the coefficients?
If a molecule would have no coefficient, it is counted as 1.
C2H2(g) + O2(g) – CO2(g) +
H20(1)
a 16
b 8
C 4
d 12

Silver tarnishes as silver metal reacts with hydrogen sulfide, h2s, in the air. in this reaction, dark silver sulfide, au2s, covers the surface of silver. when silver is polished, this coating of silver sulfide can be removed from the surface. this makes the silver shiny again. enter the coefficients that balance the tarnishing reaction equation. (type 1 for no coefficient.)
