chemistry
In raction NH3 + 5 O2 --> 4 NO + 6 H20 . I 1 mol NH3 and 1 mol O2. what is the limiting reactant? ow Much NO will form?

chemistry
a sample of iron are is known as Fe3O4. A 50 gram of sample contain 26 gram of Fe. Determine % yield Fe3O4 In sample

chemistry
in reaction = Mg + O2 --> MgO if 24 gram of Mg is burned in excess oxygen to form 40 gram of MgO, How much O2 is used?

chemistry
thank you
