Question

Please need help. How to find the equilibrium for each.

 

M 23 Le Chatelier's Principle Record your observations in a table like the one below AND use these labels for EACH equilibrium you write in your lab notebook so I can grade it.

The question is, are you making CaC₂O4(s). If 19.2 and 19.5 look the same then yes, you are making CaC₂O4(s). If 19.2 and 19.5 are different then you're making Ca(OH)2(s). Show the "seven step process" /equilibrium for 19.2 only (19.5 will be negative/false/no rxn). 2 3 4 5 16 7 8 Yellow Yellow Yellow Brown dark brown Pink
