Answer:
–2
Explanation:
Data obtained from the question:
Number of electron = 16
Valence electron = 6
Now, let us write the electronic configuration for sulphur. This is illustrated below:
1s2 2s22p6 3s23p4
From the above, we can see that sulphur will be needing 2 extra electrons to complete its octet configuration. Therefore, the oxidation number of the sulphur will be –2.
The minus sign indicate that the sulphur will accept 2 electrons to complete its octet configuration
Answer:
the answer is a because thermal energy is heat and the question said that is not a factor of thermal energy so A does not refer to heat
Answer:
D is the most soluble in water at 60 degrees Celsius
Answer:
endothermic means energy is taken in and temperature increases.
