Answer:
There is an overall release of energy when bonds form.
Explanation:
There is a general release of energy when bonds form. This energy is called bond energy.
Bond energy is involved in the breakdown or formation of one or more bonds between atoms of a molecule. Atoms bond with each other to achieve their electronic stability, that is, they move from a higher energy situation to a lower energy one. With this we can state that when the bond between atoms is formed, energy is released; therefore, its breakdown depends on energy absorption.
Answer:
The behaviour of gases is described in terms of kinetic theory , which considers the motion of molecules in the gas . The gas link pressure , volume and temperature .
Explanation:
Answer : The enthalpy of this reaction is, 1.06 kJ/mol
Explanation :
First we have to calculate the heat produced.
where,
q = heat produced = ?
m = mass of solution = 137 g
c = specific heat capacity of water =
= initial temperature =
= final temperature =
Now put all the given values in the above formula, we get:
Now we have to calculate the enthalpy of this reaction.
where,
= enthalpy change = ?
q = heat released = 2.12 kJ
n = moles of compound = 2.00 mol
Now put all the given values in the above formula, we get:
Thus, the enthalpy of this reaction is, 1.06 kJ/mol
Moles = Molarity x Volume
Moles = 2.0 x 0.50
= 1.0 mole
hope this helps!
