Answer:
0.01981 gallons.
Explanation:
In this problem, we need to convert 75 mL of water to gallons.
We know that, 1 gallon = 3785.41 mL
To convert 75 mL to gallons, we must use to the unitary method such that,
1 mL = (1/3785.41) gallon
So,
So, there are 0.01981 gallons in 75 mL of water.
It is the bond in hydrogen.
Reason: The attraction between hydrogen and the electronegative atoms form the polar covalent bond. This bond can result in partial charges and attraction of molecules with opposite partial charges.
Answer:
B. overlap of two d orbitals end to end overlap of p orbital.
Explanation:
Sigma bonds are the strongest type of bonds and they are covalent which is due to the direct or end to end overlap of orbitals. The symbol σ is used to adequately describe the bond that exists in a molecule.
In organic molecules, a single C-C bond is a sigma bond while a multiple C-C bond is composed of one sigma bond together with pi or other bonds that is a double bond has one sigma plus one pi bond, and a triple bond has one sigma plus two pi bonds.
Examples include: s-s orbital, pz-pz orbitals, dz-dz orbital and hybrids like sp-p etc.
Melt chocolate and measure the temperature and then melt wax and measure the temperature and compare his results.

This page has all of the required homework for the material covered in the third exam of the first semester of General Chemistry. The textbook associated with this homework is CHEMISTRY The Central Science by Brown, LeMay, et.al. The last edition I required students to buy was the 12th edition (CHEMISTRY The Central Science, 12th ed. by Brown, LeMay, Bursten, Murphy and Woodward), but any edition of this text will do for this course.
Note: You are expected to go to the end of chapter problems in your textbook, find similar questions, and work out those problems as well. This is just the required list of problems for quiz purposes. You should also study the Exercises within the chapters. The exercises are worked out examples of the questions at the back of the chapter. The study guide also has worked out examples.
These are bare-bones questions. The textbook questions will have additional information that may be useful and that connects the problems to real life applications, many of them in biology.
