Ammonia (NH3) and oxygen combine to form nitrogen monoxide (NO) and water by the chemical reaction:4 NH3(g) + 5 O2(g) → 4 NO(g) + 6 H2O(l) If 100 grams of ammonia are reacted with 200 grams of oxygen Which reagent is the limiting reagent? is it oxygen or ammonia

The tendency of water molecules to stick together is referred to as a) adhesion b) polarity c) cohesion d) transpiration e) evaporation

Iron (3) oxide will decompose in the presence of hydrogen gas and heater to produced iron and digydrogen monoxide white a balanced chemical equation
