What would happen if there was no green house effect

earth would start to freeze up because there is nothing heating it up

Without naturally occurring greenhouse gases, Earth's average temperature

would be very low compared to how it is currently

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.
