Question

Write balanced chemical equations for the following reaction:

(a)Natural gas burns in air to form carbon dioxide and water.

(b)Sodium metal reacts with water.

© iron (III)oxide reacts with aluminium and give molten iron and aluminium oxid

Answer 1

Answer:

$(a) = CH4(g)+O2(g)→CO2(g)+H2O(g)$

where CH4 is natural gas,O2 is oxygen,CO2 is Carbon dioxide and H2O is water...

$(b) = 2Na+2H2O→2NaOH+H2..$

where Na is sodium, H2O is water, NaOH is sodium hydroxide and H2 is hydrogen gas....

$(c)2Al(s)+Fe2O3(s)→Al2O3(s)+2Fe(l)+heat.$

where Al is aluminium, Fe is iron and Al2O3 is Aluminium oxide....
