Answer:
The answer to your question is: d
Explanation:
Electron configuration of Carbon.
Atomic number of carbon = 6
a) 1s²2s²2p¹ Number of electrons = 5, This is the electron configuration of Boron.
b) 1s²2s²2p⁴ Number of electrons = 8. This is the electron configuration of oxygen.
c) 1s²2s²p² Number of electrons = 6. This is the electron configuration of carbon. But I think is lacking a number two before p.
d) 1s²2s²2p² Number of electrons 6, This is the correct electron configuration of carbon.
Answer:
8.7g/mL
Explanation:
I used the density formula to solve. d=m/v= 20g/2.3mL
The answer is C. Free Energy.
Activation energy is the energy that must be exceeded before a chemical reaction can occur. Free energy best describes as energy available to do work.
