I think the correct answer would be B. Octane is a component of fuel used in internal combustion engines. the dominant intermolecular forces in octane are london dispersion forces. Dipole-dipole bonds happens only with polar substances. Hydrogen bonding occurs when H bonds with an O, F or N atom. Covalent bonds are not intermolecular force rather it is an intramolecular force. Carbon-Hydrogen bonds, as far as I know, are not a type of bond, intermolecular or intramolecular. So, we are left with london dispersion force. It is a temporary force that happens when electrons of two atoms in adjacent would occupy positions that would form dipoles temporarily.
Answer:
I believe the answer would be Air
Answer:
12 moles of F₂
Explanation:
We'll begin by writing the balanced equation for the reaction. This is illustrated below:
N₂ + 3F₂ —> 2NF₃
From the balanced equation above,
3 moles of F₂ reacted to produce 2 moles of NF₃.
Finally, we shall determine the number of mole of F₂ needed to produce 8 moles of NF₃. This can be obtained as illustrated below:
From the balanced equation above,
3 moles of F₂ reacted to produce 2 moles of NF₃.
Therefore, Xmol of F₂ will react to produce 8 moles of NF₃ i.e
Xmol of F₂ = (3 × 8)/2
Xmol of F₂ = 12 moles
Thus, 12 moles of F₂ is needed for the reaction.
Answer:
D. His device would not be successful because radio waves do not have enough energy to kill the bacteria.
