2H₂O → 2H₂ + O₂ Use the above balanced equation to answer the following questions:
How many moles of O₂ will be produced from 6.2 moles of water?
How many grams of O₂ will be produced

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.)

What is the mass of each element in a 324.8 sample of co2

Calculate the mass of silver needed to react with chlorine to produce 126g if silver chloride?
