The
combustion of heptane (C7H16) in oxygen spontaneously occurs. The products of
the reaction are carbon dioxide and water vapor. The balanced chemical equation
is 7H16 + 11O2 → 7CO2 + 8H2O H
= –2877.5 kJ.
Answer:percent composition
Explanation:
Answer :
The steps involved in the lewis-dot structure of
are :
- First we have to determine the total number of valence electron in
.
Number of valence electrons in S = 6
Number of valence electrons in two F atom = 2(7) = 14
Total number of valence electrons = 6 + 14 = 20 electrons
- Placing a bonding pair of electrons between the atoms to form the chemical bonds.
Electrons used in bonding = 4
- The remaining electrons are used as a lone pair for central or terminal atoms to achieve an octet to finish the Lewis dot structure.
Electrons used as a lone pair = 20 - 4 = 16

Fusion and fission are both nuclear reactions that produce energy, but fusion is two nucleus joining (think about fuse or fusing), while fission is a nucleus splitting (think about fissure)
so the correct answer is <span>C. Fission is the splitting of a nucleus</span>
