Why is the brcl molecule polar? the shared electrons are closer to cl due to the greater electronegativity of chlorine. bromine

has a large positive nucleus. three-dimensional geometry is asymmetrical. chlorine gains an electron whereas bromine loses one?

The shared electrons are closer to Cl due to the greater electronegativity of chlorine.

Answer: the shared electrons are closer to cl due to the greater electronegativity of chlorine.


Justification:


1) In a covalent bond (the bond between two non-metal elements) the electrons are shared.


2) When the two elements have different electronegativities the electrons are not evely shared: the element with the greatest electronegativity will pull the electrons with higher strength.


3) As consequence the electrons will be closer to the most electronegative atom creating a dipole moment, which is what causes the molecule to be polar.


4) You can learn the trend of electronegativity in the periodic table: in a group the electronegativity decreases downward. With this you do not need a table with the values of the electronegativities and can predict that the electronegativity of Cl is greater than the electronegativity of Br.


5) From above statements you can conclude that, due to its greater electronegativity, chorine will pull the electrons with greater strength, causing the molecule to be polar.

Write an equation that expresses the law of thermodynamics in terms of heat and work
Anettt [7]

We write DE = q+w, where DE is the internal energy change and q and w are heat and work, respectively.

(b)Under what conditions will the quantities q and w be negative numbers?

q is negative when heat flows from the system to the surroundings, and w is negative when the system does work on the surroundings.

As an aside: In applying the first law, do we need to measure the internal energy of a system? Explain.

The absolute internal energy of a system cannot be measured, at least in any practical sense. The internal energy encompasses the kinetic energy of all moving particles in the system, including subatomic particles, as well as the electrostatic potential energies between all these particles. We can measure the change in internal energy (DE) as the result of a chemical or physical change, but we cannot determine the absolute internal energy of either the initial or the final state. The first law allows us to calculate the change in internal energy during a transformation by calculating the heat and work exchanged between the system and its surroundings.

HELP . Read the following graduated cylinder.
Anon25 [30]

The volume of the liquid from the graduated cylinder is 22.5 mL

The last option (22.5 mL) is the correct option

The question seems to be incomplete

The image that completes the question is shown in the attachment below.

From the image, we observe that the liquid meniscus is between the 20 mL and 25 mL marks. That means the volume will lie in this range.

NOTE: The meniscus of a liquid is the upward or downward curve seen at the top of a liquid in a container.

The type of curve shown in the image is a concave meniscus and the volume of the liquid is read from the bottom of the curve.

To read the value from the graduated cylinder, we will first determine the difference between two consecutive lines. Between the 20 mL and 25 mL mark (two thick lines), we have 5 spaces separated by thin lines.

The measure between two consecutive lines is the difference between two thick lines divided by number of spaces between them

∴ The measure between two consecutive lines = (25mL - 20mL) ÷ 5

The measure between two consecutive lines = 5mL ÷ 5 = 1 mL

Now, to read the position of the liquid,

Starting from the 20 mL mark, the liquid exceeds two more lines + half way to the next line ( that is 2mL + 0.5 mL)

∴ The position of the liquid is 20 mL + 2mL + 0.5 mL = 22.5 mL

Hence, the volume of the liquid from the graduated cylinder is 22.5 mL
