The valence part is referring to the outer most ring of electrons. Carbon only has four on the 'valence' or outer most ring helping it to form bonds with other things. I hope this helps!! Good Luck!!! :)
It has the slowest rotation of all planets.
like 240 earth days...in retrograde clockwise turns
Long wave I think is the correct answer
Thomson's atomic model is a theory about the atomic structure proposed in 1904 by Thomson, who discovered the electron in 1897, a few years before the discovery of the proton and the neutron.
Hope this helps :))
You need to first write a chemical equation and balance it
C₄H₁₀ + O₂ → CO₂ + H₂O
2 C₄H₁₀ + 13 O₂ → 8 CO₂ + 10 H₂O
1.0 moles X moles
1.0 mol C₄H₁₀ (

) = 4 moles of CO₂
