1)Delta H=(Delta H of reactants)-(Delta H of products)
2)And we know CO have 3 bond CO and CO2 have 2 bond that each of them are 2 bond, please see the picture!
so lets answer it:

Answer:
When salt is mixed with water, the salt dissolves because the covalent bonds of water are stronger than the ionic bonds in the salt molecules. ... Water molecules pull the sodium and chloride ions apart, breaking the ionic bond that held them together.
Explanation:
Explanation:
Expression for the kinetic energy is as follows.
K.E =
Now, total kinetic energy will be as follows.
K.E =
=
Since, this energy converts into electromagnetic radiation of wavelength 121.6 nm.
Relation between energy and photon is as follows.
Energy of photon =
=
=
v =
=
m/s
Thus, we can conclude that atoms were moving at a speed of
m/s before the collision.
