Which of the following compounds below would possess it trigonal planar molecule or geometry?
PHOTO ABOVE
HELP ME IN MY TEST
Answer:
B - BF3
Explanation:
BF3 has 3 bonds around the central atom and now lone pairs on it. This matches the geometry of a trigonal planar molecule as per the VSEPR Model.
Molecules have two distinct characteristics: form and geometry. Geometry includes the lone pair encircling the focal element whereas shape excludes it. Therefore, the correct option is option B.
What is VSEPR theory?Valence shell electron repulsive force is what VSEPR stands for. Based on the valence electron pairs that are prevalent around the core element of the molecule, the VSEPR theory is employed to predict the structure and geometry of molecules.
According to VSEPR theory, Lone pair lone pair repulsion is greater than bond pair bond pair repulsion. The core atom of BF[tex]_3[/tex] is surrounded by three bonds and contains no lone pairs. According to the VSEPR Model, this corresponds to the geometry of such a trigonal planar molecule.
Therefore, the correct option is option B.

Answer:
100°C
Explanation:
The boiling point of water is 100°C and the difference is when will the water start boiling.

9A. A sample of hydrogen at 1.56 atm had it's pressure decreased to 0.73
atm producing a new volume of 751 mL. What was its original volume? *
Answer:
351.43mL
Explanation:
To calculate the original volume of hydrogen gas in this question, the Boyle's law equation will be used. Boyle's law equation is:
P1V1 = P2V2
Where; P1 = initial pressure
V1 = initial volume
P2 = final pressure
V2 = final volume
According to this question, the P1= 1.56atm, V1 = ?, P2 = 0.73atm, V2 = 751mL
Hence;
P1V1 = P2V2
1.56 × V1 = 0.73 × 751
1.56 V1 = 548.23
V1 = 548.23/1.56
V1 = 351.43mL
Therefore, the original volume of hydrogen gas is 351.43 mL.

Which has a smaller ionic radius than it's neutral atom?
A. Iodine
B.Cesium
C.Oxygen
D.Nitrogen
Explanation:
Caesium (Cs) has a smaller ionic radius than it's neutral atom.
because Caesium belong to Group 1 and It loses 1 electron. After losing 1 electron it gains 1 positive charge that's why caesium ionic radius become smaller as compared to neutral atom.
Therefore,
Option B is correct.

An atom with the electron configuration 2-8-8-2 has an incomplete
Answer:
3rd principal energy level
Explanation:
Principle energy that explains the energy of the electrons and positions of electrons of a particular atom. There are four energy levels fist to fourth that are made of sublevels and that is made up of s, p, d and f orbitals.
First principal energy level - 2
Second principal energy level - 8
Third principal energy level - 18
Fourth principal energy level - 32
3rd energy level has 9 orbitals, which has 18 electrons
2 in the s orbital,
6 in the three p orbitals, and
10 in the five d orbitals.
So, here there are only 8 electrons in the third principal energy level.

What is the conversion factor used when converting mass to moles?
In such a conversion, we use the molar mass of a substance as a factor to convert that to mole units into mass units (or, conversely, mass units into mole units).
Then We also established that 1 mol of Al incorporates a mass of 26.98 g (Example). Stated mathematically that is, 1 mol Al = 26.98 g Al
Molar massNow, This relation provides a factor to travel from grams to moles.
which is help to Using the factor 98.08 g / 1 mol: grams H 2 SO 4 = 3.60 Then mol x 98.08 g / 1 mol = 353 g H 2 SO 4

Which relationship is an example of commensalism?
A )A diamondback rattlesnake and a gopher turtle share a burrow. The turtle digs the hole, and the snake provides protection from predators for the turtle.
B)Remora fish stick to large sharks, receiving a free ride and scraps of food the shark does not eat. The shark is neither helped nor harmed.
C)Hyenas and lions fight over the same antelope kill.
D)A tapeworm lives in the intestine of a dog, obtaining food for itself, while slowly harming the dog.
Answer:
The correct answer is option
B) "Remora fish stick to large sharks, receiving a free ride and scraps of food the shark does not eat. The shark is neither helped nor harmed".
Explanation:
Commensalism is defined as a type of inter-species relationship at which one individual gets benefited and the other is neither benefited or harmed. An example of commensalism is the one between remora fish and large sharks. In this case, remora fish gets attached to the large sharks by an organ that acts suction cup. The remora fish gets benefited by receiving transportation, a food source and protection from predators, while the large sharks are neither helped nor harmed.
