Which of the following is a correctly balanced equation? naclo3 → nacl + 3o2 2hgo → 2hg + o2 2zns + o2 → 2zno + 2so2 4co + fe3o4 → 4co2 + fe 2fe + 2cl2 → 2fecl3

The right answer is 2HgO → 2Hg + O2

Balancing a balance equation consists of finding the right stoichiometric coefficients. These coefficients (placed in front of each molecule) balance the number of each of the different atoms involved during a chemical reaction.

In this reaction, we find on both sides the same number of atoms: two oxygen atoms and two atoms of mercury.

the water is warmed up by the sun and then it evaporates into the atmosphere. the sunlight warms the water by its heat. water is then cooled down and condensation takes place. the water then finally returns back to the earth by the process of precipitation in the form of rain or ice.
