Answer 2

are we balancing chemical equations?

Answer 3

yes this is physical science

Answer 4

oh sorry didn't see the chemical part :/

Answer 5

The MnO2 was a catalyst and did not get used up in the reaction. Balance the equation for the breakdown of hydrogen peroxide

Answer 6

H2O2  H2O + O2

Answer 7

please keep in mind that number of specific atoms at left side has to be equal to number of those atoms at the right side

Answer 8

Manganese dioxide catalyses the decomposition of hydrogen.

Answer 9

for example, let's consider the subsequent equation:
\[H _{2}+\frac{ 1 }{ 2 }O_2\rightarrow H _{2}O\]
we have:
left side: there are 2 atoms of hydrogen and 1 atom of oxygen,
right side: we have 2 atoms of hydrogen and 1 atom of oxygen
