Aluminum reacts with chlorine gas to form aluminum chloride via the following reaction: 2Al(s)+3Cl2(g)→2AlCl3(s) You are given 24.0 g of aluminum and 29.0 g of chlorine gas.
1. If you had excess chlorine, how many moles of aluminum chloride could be produced from 24.0 g of aluminum?
2. If you had excess aluminum, how many moles of aluminum chloride could be produced from 29.0 g of chlorine gas, Cl2?
A sample of unknown hydrate of FeCl3 weighs 8.693g. After heating the sample to constant mass, the remaining anhydrous salt weighs 5.216g. What is the experimental formula for the hydrate
