Acyl-coa + fad ↔ trans-δ2-enoyl-coa + fadh2 (note: the double tipped arrow means forward and reverse)this is the first reaction of β-oxidation. which of the following statements about this reaction is true. fadh2 is spontaneously reduced. acyl-coa is the electron acceptor. fad is the oxidizing agent. trans-δ2-enoyl-coa has a lower affinity for electrons than fadh2.

n has four pairs of electrons in the valence shell, electrons repel one another ,n has 7 protons in its nucleus, and since n has 7 protons, it must fill the second shell, giving it 4 pairs of electrons. the electrons form 3 bonds and 1 lone pair of electrons. each pair of electrons repels the other pairs, so they are equally far apart.

so all of the above

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.
