Help with half of chemistry homework please?

9.) A lightning flash through the air may result in the formation of ammonia carbon dioxide nitric oxide water 10.) A fertilizer that may explode is ammonium nitrate ammonium sulfate potassium chloride urea 11.) What is the ratio of diatomic Nitrogen gas to Ammonia in the following equation N2+3H2 ---> 2NH3 1:2 2:2 1:3 2:8 12.) Ammonia is a compound while ammonium is (hint: answer is in lesson 17.3) a base a radical an atom an element 13.) Nitrogen dioxide is produced by reacting________ and __________. Copper and HCl Nitric Acid and concentrated Br Copper and concentrated Nitric Acid Concentrated Copper and metallic Cu 14.) The Ostwald Process is used to produce aluminum ammonia chlorine nitric acid 15.) Nitric oxide has the formula NO NO2 N2O N2O4 16.) To test for an ammonium salt heat it with Calcium NH4OH Oxygen FeSO4 and H2SO4 17.) The catalyst used in the Haber Process is iron oxide platinum manganese dioxide vanadium pentoxide 18.) The presence of water vapor in the air may be demonstrated by the use of phosphorus limewater sodium hydroxide magnesium nitride

1. 1 = nitrous oxide. The heat fuses Oxygen and Nitrogen, which the atmosphere is composed mostly of. 2 = ammonium nitrate. The molecule contains the two ingredirnts needed for an explosive , oxodozer (nitrate) and oxidant (ammonium). This generates an inceredibly powerful shock wave as it detonates. It was what took out the OK federal building. In the 1930's a barge filled with this stuff caught fire and severly damaged several city blocks on the Texas coast. The ship was blown into such tiny bits it could never be found. 3 = check the left hand coefficients of N2+3H2 ---> 2NH3 ; these are the ratios. 1:2 ought to be the ratio of Nitrogen to Ammonia. 4 = Ammonium hydroxide is a basic ion. Ammonia combnes with water to form a weak base, NH3 + H2O = NH4OH. The hydroxyl group (OH) makes it a base. 5 = let's see ... NO. Copper and HCl = CuCl2 + H2 Nitric Acid and concentrated Br (probably not) Concentrated Copper and metallic Cu ? Cu + Cu = 2Cu (RU serious??) Copper and concentrated Nitric Acid = YES!!! 6 = Ammonia is my guess, since this homework assignment seems so full of sh---aving cream! 7 = NO. Yes, it's NO. 8 = Calcium most likley, since the pure metal would do something like: Ca + 2NH4Cl -> CaCl2 + 2NH3 + H2 The ammonia would be immediately evident by anyone whose face included a nose. Iron sulfate , FeSO4, would just form ferric ammonium sulfate and ammonium sulfate. Oxygen and ammonium chloride do not react at all. 9 = I'm not sure at all about this one. Platinum and vanadium pentoxide are well known catylists. I'd choose the vanadium, V2O5. of course I'm guessing. Homework time! 10 = Another sh---aving cream question. Magnesium nitride. I'll wager half a ton of NH4NO3 the reaction is: Mg3N2 + 6H2O -> 2NH3 + 3Mg(OH)2 Again, the ammonia would be immediately detectable.
