Two or more elements chemically combined, whose properties are completely different from those of the individual elements, are known as a
A. Compound
B. Heterogeneous mixture
C. Homogeneous mixture
D. Solution

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.

i wish i could but this one is weird give me abc and i can solve it.
