(i) A balloon filled with hydrogen gas explodes upon contact with a spark. |
|
Answer» Hydrogen GAS is very FLAMMABLE. This is why the balloon filled with hydrogen ignites. The heat given off by the candle provides the activation energy REQUIRED for the reaction that produces water from hydrogen and OXYGEN. This reaction is highly exothermic, producing the prodigious explosion.PLS MARK AS BRAINLIEST! |
