Question

State the type of chemical reactions and chemical equations that take place in the following

following:

(i) Magnesium wire is burnt in air.

(ii) Electric current is passed through water.​

Answer 1

i)Combination reaction: 2Mg+O2→2MgO

ii)Decomposition reaction: 2H2O→2H2+ O2.

hope this will help

Answer 2

Answer:

. When magnesium Wire is Burnt in air, then magnesium oxide is formed. Here, two reactants reacts to form a single compound. So, it is a Combination Reaction

When electric current is passed through water, then it decomposes to form Hydrogen and Oxygen ion
