The answer is The loudness of sound is related to its amplitude, this is off edmentum exactly so I advise changing up the wording. You can say something about the pitch or you can word it like, The sound of the wave is related to how loud the sound can be. Hope this helped
Answer:
I. FALSE
II. FALSE
III. TRUE
IV. TRUE
Explanation:
<em>I. A set of sp² orbitals can be thought of as one s orbital one-third of the time and two p orbitals two-thirds of the time.</em> FALSE. 1 s orbital hybridize with 2 p orbitals to form 3 sp² permanent orbitals.
<em>II. A set of sp orbitals can accommodate a maximum of six electrons. </em>FALSE. sp orbitals, as any orbital, can accommodate a maximum of 2 electrons.
<em>III. The orbitals resulting from sp³d² hybridization are directed toward the corners of an octahedron.</em> TRUE. 1 s orbital, 3 p orbitals and 2 d orbitals hybridize to form 6 sp³d² orbitals, which are directed toward the corners of an octahedron.
<em>IV. A set of sp³ orbitals results from the mixing of one s orbital and three p orbitals.</em> TRUE. 1 s orbital hybridize with 3 p orbitals to form 4 sp³ orbitals.

I just took the test for you the answer is A molecular formula gives only the number and kind of atoms present in a molecule. THIS IS COPYED STRAIGHT FROM THE TEST. have a good day :)
Answer:
2.67 g/mL
Explanation:
Initial Volume of water = 10.0 mL
Final Volume pf water = 15.46 mL
Mass = 14.74g
Density = Mass / Volume of aluminium
Volume of aluminium = Final Volume of water - Initial Volume of water = 15.46 - 10 = 5.46mL
Density = 14.74 / 5.46 = 2.67 g/mL
