Answer:
chemical change
Explanation:
because chemical chande is a permanent change
Answer:
yes....
Explanation:
Let me explain the molecular orbital diagram of N2 using its diagram.
one atom of nitrogen has 7 electrons so a N2 molecule will have 14 electrons
so first 2 electrons go in 1s sigma bond
next 2 in 1s sigma anti bond orbital
next 2 in 2s sigma bond orbital
next 2 in 2s sigma anti bond orbital
next 2 in 2pz sigma bond( assuming that z axis is the internuclear axis ) orbital
Mole number of 75 g is 0.4 mol. NO2 is 0.8 mol and is 36.8 g.
