Which is the conjugate base! Which is the conjugate acid? On which side does the equilibrium lie? right or left CHEM 104 FALL 2021 18) Use LeChatelier's principle to indicate in the table below whether cach change will shift the equilibrium right, left or not at all (L, R. NC), and whether the quantity in the third column increases, decreases, or does not change tid, nc) HCl(aq) + CaCO3(s) * Call2(aq) + CO2(g) +A This is left This is right og shifts LRNC LRNC id nc When this change is made, the Add CaCla) Remove HCI Add CaCO3(-) Heat the reaction Decrease the volume And the following will Cacosmass CaCl: concentration CaCl concentration id LRNC LRNC Value of i dne i dne id nc LRNC Value of K acid Parket Stranger or 19) Consider the equation HF + 1* **HA+F" Ke > 1 to answer the following questions Based on the equation lies to the which means that HA is a than HF. 20) Organize the conjugate bases of the following acids from most basic to least basic, HF K.-7.2x10 HCIO, K. - 1.2x102 least basie K- 21) Which of the following mixtures would form a good buffer?
