False, Molecules are made of atoms and atoms are made of quarks.
Answer:
The oeriodic table have 8 groups
For this reaction to proceed, the following bond breaking should occur:
*one C-H bond
* one Cl-Cl bond
After, the following bond formations should occur:
*one C-Cl bond
*one H-Cl bond
Now, add the bond energies for the respective bond energies which can be found in the attached picture. For bond formations, energy is negative. For bond breaking, energy is positive.
ΔHrxn = (1)(413) + (1)(242) + 1(-328) + 1(-431) =
<em>-104 kJ</em>
True !! size dependent properties state is only one of the many physical properties of matter some physical properties such as massive value depending on the size or the amount measures of these properties very depending on how much matter is in a sample.
