Answer:
Crust (the surface)
Upper Mantle (dense magma)
Lower Mantle (less dense magma)
Outer Core (pure liquid material)
Inner Core (dense material)
Hope that helps
The geometry of the double bond is almost always a cis configuration in natural fatty acids<span>. These molecules </span>do<span> not "stack" very well. The intermolecular interactions are much weaker than </span>saturated <span>molecules. As a result, the melting </span>points<span> are much </span>lower<span> for </span>unsaturated fatty acids<span>.
I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!

Hi there!
We can use the following conversions to solve:
Total mass --> amount of mols --> amount of atoms (Avogadro's number)
Begin by calculating the amount of boron trifluoride in 3.61 grams:
3.61 g * (1 mol BF₃ / 67.8 g) ≈ 0.0532 mol BF₃
Use avogadro's number to convert:
0.0532 mol * 6.02× 10²³atoms / 1 mol = 3.203 × 10²² atoms
Answer:
coal
Explanation:
fossil fuels are formed by natural process.
