This gas burn when we bring the candle to it. Zinc also react with weak acids like acetic acid, but here gas formation is slow.Explanation:Zinc reacts with acids and forms its salt and hydrogen gas. Hydrogen gas liberates as the bubble. When we bring the flame to this gas, it burns as hydrogen is highly flammable.

So its reaction with zinc is slower as compared to strong acids like Hydrochloric acid and sulphuric acid.
