Pair_Coeff. # Interactions with carbonate

Dear Gentlemen,

I am about to finish my simulation but I am getting an error about Incorrect pair coefficients. I had this issue before but I fixed it up. However, I am getting the error for different issue now, which I was not able to tackle, the Buckingham parameters from a published paper for a work similar to mine. Please check below.

Your valuable collaboration and efforts are highly appreciated

As the error message indicates, your pair_coeff lines are incorrect. They follow the requirements of a hybrid pair style.
