An example of an extensive property of matter is "mass"
N76 [4]3 years ago

Answer:

Examples of extensive properties are: temperature, mass, weight, volume, lenght, force, among others.

Explanation:

Extensive properties are properties that depends on the amount of mass (thus depends on the size) of an object.

For example:

It is not the same to have a package of 1 kg of sugar than a package of 5 kg of sugar. The amount of mass is different and also the weight and the volume (the 1 kg package take less place than the package of 5 kg).

Also exists  Intensive properties, these ones do not depends on the amount of mass, such as: density, organoleptic properties, boiling point, melting point, amog others.

In the previous example, the flavor of both packages of sugar will be the same independetly of the amount of sugar.

Gases A and B are confined to a cylinder and piston and react to form product C. As the reaction occurs, the system loses 1189 J
aliya0001 [1]

Answer:

The change in the internal energy of the system -878 J

Explanation:

Given;

energy lost by the system due to heat, Q = -1189 J (negative because energy was lost by the system)

Work done on the system, W = -311 J (negative because work was done on the system)

change in internal energy of the system, Δ U = ?

First law of thermodynamics states that the change in internal energy of a system (ΔU) equals the net heat transfer into the system (Q) minus the net work done by the system (W).

ΔU = Q - W

ΔU = -1189 - (-311)

ΔU = -1189 + 311

ΔU = -878 J

Therefore, the change in the internal energy of the system -878 J

How many of the following molecules have sp2 hybridization on the central atom? hcn so2 ocl2 xecl2.
GrogVix [38]

Only one molecule have <u>sp2 </u>hybridization on central atom and that is <u>SO₂</u>.

<u>XeCl₂</u> have <u>sp3d </u>hybridization.

<u>OCl₂</u> have <u>sp3 </u>hybridization.

<u>HCN </u>have <u>sp </u>hybridization.

Hybridization is defined as the concept of mixing two atomic orbitals to give rise to a new type of hybridized orbitals.

Hybridization intermixing usually results in the formation of hybrid orbitals having entirely different energies, shapes, etc.
