occurs when someone takes an antacid? Check all that apply.
HCI + NaOH → NaCl + H2O
2HCI + CaCO3 – CaCl2 + CO2 + H20
2HCI + Mg(OH)2 → MgCl2 + 2H2O
6HCI + 2A1 - 2AlCl3 + 3H2

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.)
