Given that the approximate atomic weights of carbon, hydrogen & oxygen are 12,1 and 16, which of the following
represents the molar mass of one mole of phenolphthalein, in
units of g/mol?
(2012) - (14 1) + (4 16)
0 1 2+1 +16
12 1 16
12012) - 11
(11

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 dependant variable is spilled water

the independent is the heat

the answer is option a.
