Part 1: Write the complete balanced MOLECULAR equation (including all states of matter) for the precipitation reaction that occurs between aqueous copper(ll) chloride and aqueous sodium hydroxide .

Suppose that during that icy hot lab 65,000 j of energy were transferred to 450 g of water at 20°c what would have have been the final temperature of the water

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.)

If a polyatomic ionic compound has gained two hydrogen ions, then how does its name begin?
