Answer:
4
Explanation:
It has 8 O atoms and 4 O2(g) molecules
Answer:
liquid phase
Explanation:
it is liquid phase because molecules are not that tightly packed as solid and not that far away from each other as in gas phase.
Answer:
Velocity has both speed and direction. Speed is constant. ... Speed is measured over time.
Explanation:
Answer:E = hc/? = 4.41 x 10-19 J
Energy absorbed by each atom :
E (atom) = 2.205 x 10-19 J
Now Bond Energy of each molecule (B) = 3.98 x J
So, for each atom 1.99 x 10-19 J
So now
KE of each atom = E(atom) - B (atom)
= 2.15 x 10-19 J
