how many grams of calcium carbonate are needed to produce 374 mL of carbon dioxide gas at STP?
Other than S=C=S; can I have S triple bonded to C single bonded to S? Wouldn't there be three electrons left on the triple bonded S; it would be sharing three when it started with six I don't understand? Help please.
when a current of 0.156A is passed through a solution of lead(II) nitrate, lead is deposited at the cathode. How long will it take to deposit 0.10g of lead?
