8
It’s 8 bc I said it was 8 ;)
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:
B) Melting of a solid.
Explanation:
- Kindly, see the attached image.
- It is known that the substance has different 3 phases (solid, liquid, and gas).
- By heating, the substance converted from solid phase to liquid phase passing by a plateau that represents equilibrium between the two phases.
- By further heating, the solid completely converted into liquid phase, then converted to gaseous phase passing by a plateau that represents an equilibrium between the liquid an gaseous phase.
<em>The plateau at the lower temperature represent: B) Melting of a solid.</em>
Answer: Energy = 10000J - 2000J = 8000J
Therefore, the energy is dissipated the skier moves down to the slope is 8000J
Explanation:
Answer:
organic
Explanation:
Organic substances are those which contains covalently linked carbon to hydrogen (C-H) bonds in their structure. In other words, organic compounds or substances are uniquely composed of carbon and hydrogen atoms covalently linked together.
These substances usually contain a long chain of these bonds, hence, making them complex. Therefore, according to this question, substanves that are complex molecules and contain carbon atoms bonded to hydrogen atoms are referred to as ORGANIC SUBSTANCES.
