What volume will 2.00 moles of nitrogen occupy at 720 mmHg and 20.0°C?

your answer would be a. 12.5 kg

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.

we need the questions , i may then you.
