I need help solving the molar mass for Procyanidin It’s:
C30 H20 012

What is the equilibrium constant of aa+bb=cc+dd

Identify a specific example for each type of technology

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.)
