Identify the substance getting oxidised and the one getting reduced. (They are inert metals- lowest in reactivity series) Metals like aluminium, zinc, iron do not react with hot/cold water ; they react only with steam to form a metal oxide and hydrogen .Manganese reacts slowly with cold water, but more rapidly with hot water or steam. Laboratory preparation of hydrogen gas. Please enable Cookies and reload the page. Zinc virtually has no reaction with cold water. If you were silly enough to try reacting potassium, sodium, lithium or calcium with steam, the resulting reaction would be so violent that the metal would explode, igniting the hydrogen in a fiery ball! Zinc being more reactive than copper displaced copper from copper sulphate. Download the … The zinc reacts slower with the steam than magnesium and does not glow brightly as it is converted to zinc oxide. In the following chemical reaction “zinc oxide reacts with carbon to produce zinc metal and carbon monoxide”. This is also an oxidation process (carbon is oxidised) and therefore a reduction (copper is reduced). Lakhmir Singh Chemistry Class 10 Solutions for Chapter 1 Chemical Reactions and Equations is provided here according to the latest CBSE syllabus. Heating the zinc will speed up the reaction but it will still not burn brightly like the magnesium. Metals like lead, copper, silver and gold do not react with water or steam.
