Correctly balance this equation H202->H2O+O2

2H202(l) --> 2H2O(l) + O2(g)

Explanation:

The balanced equation above represent the decomposition of hydrogen peroxide (H2O2) to yield liquid water (H2O) and liberate oxygen gas (O2) without any heating.

In the laboratory, the rate of decomposition is increased in the presence of manganese (IV) oxide as catalyst.

put the answers   and i could answer.

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.
