Which is the correct Lewis dot structure of C2H2

Chemistry
1 answer:
denpristay [2]4 years ago
3 0

The correct answer is A

The octet rule state that all main group elements form bonds such that they achieve a noble gas configuration with eight valence electrons. In this case carbon has 4 electrons in its outermost shell  and requires 4 more electrons to achieve an octet. Hydrogen is an exception to the octet rule and it only requires two electrons to achieve an octet. All the other options have C and H  forming bonds that do not lead to a noble gas configuration.

1. 100 C

2. Point B to C is the ices heat capacity

3. During the points D to E the bonds of the water molecules build up enough kinetic energy to break their intermolecular bonds (not intra), which can lead to gas.

4. Between points D and E the energy is being released the energy required is equivalent along the line.

5. Between point E and D the water is converting to water (condensation)

6. Energy is being released 2260 j/g

7. Yes, but only under extreme volumetric pressures

8. D and E or B and C

9. Freezing (the water is also becoming less dense)

10. Melting or if water already, absorbtion of energy

11. released.
