Analyze how limestone is weathered and identify the features that are formed as a result of this dissolution

How many moles of no2 will form when 3.3 moles of cu are reacted with excess hno3?

How does the value of the equilibrium constant show that a reaction reaches equilibrium very quickly? (a) the equilibrium constant is large. (b) the equilibrium constant is small. (c) the equilibrium constant is zero. (d) the value of the equilibrium constant does not show how quickly a reaction comes to equilibrium.
