Write a balanced equation formed when the following elements react with oxygen:a)Zinc b)Carbon

c)Sulphur

d)Calcium

e)Magnesium

f)Sodium
Please help me. If possible explain.

Explanation:

a) when zinc burnt in oxygen.

2Zn + O2 ∆> 2ZnO(black residue)

b) when carbon burnt in oxygen.

C+O2∆---> CO2.

c) when sulphur burnt in oxygen.

S+O2∆> SO2.

d) when Calcium burnt in oxygen.

2Ca+O2∆> 2CaO(black residue)

e) when Magnesium burnt in oxygen.

2Mg+O2∆> 2MgO.

f) when sodium burnt in oxygen.

4Na+O2∆> 2Na2O.

hope all these reactions help you.

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.

if it's not useful, feel free to report for mistake in answer.
