Go to the molecules mode by selecting the icon at the bottom. notice that there are three real reactions: the synthesis of water, the synthesis of ammonia, and the combustion of methane. select each of the reactions and observe the reactants taking part in the reactions. suppose you are carrying out each of these reactions starting with five moles of each reactant. observe that some reactants are in excess whereas some reactants limit the amount of products formed. classify each of the reactants as a limiting reactant or an excess reactant for a reaction starting with five moles of each reactant. drag the appropriate items to their respective bins.

Aluminum reacts with chlorine gas to form aluminum chloride via the following reaction: 2al(s)+3cl2(g)→2alcl3(s) what is the maximum mass of aluminum chloride that can be formed when reacting 32.0 g of aluminum with 37.0 g of chlorine? express your answer to three significant figures and include the appropriate units.

Astudent is given a sample of a blue copper sulfate hydrate. he weighs the sample in a dry covered porcelain crucible and got a mass of 23.875 g for the crucible, lid, and sample. the mass of the empty crucible and lid was found earlier to be 22.652 g. he then heats the crucible to expel the water of hydration, keeping the crucible at red heat for 10 minutes with the lid slightly ajar. on colling, he finds the mass of crucible, lid, and contents to be 23.403 g. the sample was changed in the process to very light clue anhydrous cuso4. if there are again 100.0 g of hydrate, how many grams of cuso4 are in it? how many moles of cuso4? (hint: molar mass of cuso4 = 159.6 g / mole. what per cent of the hydrate is cuso4? you may convert the mass of cuso4 to moles.)

Ineed ! i have no clue how to do this problem.
