Old thermometers contained very small amounts of mercury. The mercury in the photo has a melting point of -38.8 degrees Celsius.

What can you conclude about the melting point of the mercury in old thermometers? *
It's melting point can only be determined when the mercury is burned.
It's melting point changes as the temperature of mercury changes.
It's melting point equals -38.8 degrees Celsius because it is mercury.
It's melting point is less than -38.8 degrees Celsius because its volume is smaller.

Predict the geometry around the central atom in SO2- A) trigonal pyramidal B) tetrahedral C) octahedral D) trigonal planar E) tr
liubo4ka [24]

<u>Answer:</u> The correct answer is Option D.

<u>Explanation:</u>

To calculate the hybridization of SO_2, we use the equation:

\text{Number of electron pair}=\frac{1}{2}[V+N-C+A]

where,

V = number of valence electrons present in central atom  (S) = 6

N = number of monovalent atoms bonded to central atom  = 0

C = charge of cation  = 0

A = charge of anion = 0

Putting values in above equation, we get:

\text{Number of electron pair}=\frac{1}{2}[6]=3

The number of electron pair around the central metal atom are 3. This means that the hybridization will be sp^2 and the electronic geometry of the molecule will be trigonal planar.

Hence, the correct answer is Option D.

During beta-oxidation of fatty acids, ___________ is produced in peroxisomes but not in mitochondria. A) acetyl-CoA B) FADH 2 C)
stepan [7]

Answer:

The correct option is D

Explanation:

Normally, beta-oxidation of fatty acid occurs in the mitchondrial matrix, however, when the fatty acid chains are too long, the beta-oxidation occurs in the peroxisomes <u>where the oxidation is not attached to ATP synthesis but rather transferred (i.e high energy electrons are transferred) to O₂ to form hydrogen peroxide</u> (H₂O₂). This is the major difference between the beta-oxidation that occurs in the peroxisomes to that which occurs in the mitochondria.
