WebJul 5, 2024 · When hydrogen gas reacts is combined with oxygen gas and the mixture ignited with a spark, water is formed in a violent reaction. Lead (IV) oxide reacts with HCl to give lead (II) chloride, chlorine gas and water. Solid potassium chlorate decomposes on heating to form solid KCl and oxygen gas. WebJan 23, 2024 · For example, hydrogen chloride adds to ethene to make chloroethane: (2) CH 2 = CH 2 + HCl → CH 3 CH 2 Cl The only difference is in how fast the reactions happen with the different hydrogen halides. The rate of reaction increases as you go from HF to HCl to HBr to HI. HF > HCl > HBr > HI
