why do equal concentrations of aqueous solutions of naclo4 na2so4 and na3po4 freeze at -3.72 degrees c, -5.58 degrees c, and -7.44 degrees c respectively at standard pressure?

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.

im not exactly sure but i think its b!

i think it's letter a.

explanation:

0.07 g/cm³

1.37 g/cm³
