Which of the following electron configurations are written incorrectly?

Chemistry
1 answer:
Lynna [10]2 years ago
3 0

Answer:

The electronic configuration that are incorrectly written is 1s²2s³2p⁶, 4s²3d¹⁰4p⁷, 3s¹ and 2s²2p⁴.

Explanation:

The electronic configuration of the elements corresponds to how all the electrons of an element are arranged in energy levels and sub-levels.

There are 7 energy levels —from 1 to 7— whose sublevels are described as s, p, d and f.

All electronic configurations begin with the term "1s" —corresponding to the sublevel s of level 1— so 4s²3d¹⁰4p⁷, 3s¹ and 2s²2p⁴ are incorrectly written. In addition, 4s²3d¹⁰4p⁷ is written incorrectly because is impossible to jump from the sublevel "s" to the sublevel "d" —which is found from level 3 and up— without passing through the sublevel "p".

In the case of 1s²2s³2p⁶, the wrong thing is that the sublevel "s" can only hold two electrons, not three.

The other options are correctly written.

which statement describes the way in which energy moves between a system of reacting substances and surroundings ​
V125BC [204]

The complete question is as follows: Which statement describes the way in which energy moves between a system reacting substances in the surroundings.

A) molecule Collisions transfer thermal energy between the system and its surroundings

B) The thermal energy of the system and it’s surroundings increase

C) The potential energy of the system and it’s surroundings increases

D) molecular collisions create energy that is then released into the surroundings

Answer: The statement, molecule Collisions transfer thermal energy between the system and its surroundings describes the way in which energy moves between a system reacting substances in the surroundings.

Explanation:

When there will occur an increase in kinetic energy of molecules then there will occur more number of collisions.

When kinetic energy between these molecules tends to decrease then they will release heat energy into their surroundings.

As a result, it means that molecule collisions transfer thermal energy between the system and its surroundings.

Thus, we can conclude that the statement molecule Collisions transfer thermal energy between the system and its surroundings describes the way in which energy moves between a system reacting substances in the surroundings.

If the density of water is 1g/cm3 what is its specific gravity
MakcuM [25]

Answer:

Specific gravity is the density of asubstance divided by the density of water. Since (at standard temperature and pressure) water has a density of 1 gram/cm3, and since all of the units cancel, specific gravity is usually very close to the same value as density(but without any units).
