D)A tapeworm lives in the intestine of a dog, obtaining food for itself, while slowly harming the dog.

Answers

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.

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? *

Answers

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.

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?

Answers

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 mass

Now, 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 of the following compounds below would possess it trigonal planar molecule or geometry?
PHOTO ABOVE

HELP ME IN MY TEST

Answers

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.

Which has a smaller ionic radius than it's neutral atom?
A. Iodine
B.Cesium
C.Oxygen
D.Nitrogen

Answers

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.
