Answer:
A is the answer i am pretty sure
Answer:
The correct answer is "Temperature is a measure of the average kinetic energy of the molecules in a substance".
Explanation:
The kinetic energy of a substance is defined as the power that results from the movement of its particles. In this sense, temperature could be defined as a measure of the average kinetic energy of the molecules in a substance. Actually, temperature expressed in Kelvin degrees is directly proportional to the average of the kinetic energy. On the other hand, heat is defined as the total energy in a substance.

<h3>What is
tumor?</h3>
The Latin word for swelling is tumor. The term "tumor" is frequently used by laypeople to refer to cancerous growths, while the medical term "neoplasme" (sometimes known as "new-formation") is more appropriate in this context. A tumor can be benign or malignant; the last case is when it is the result of a cancerous growth.
The development of swelling on or within the body may also result from a variety of causes, including the toename of vocht (oedeem), an uncontrolled (lichaamsvijandige) toename of the number of cells, or a combination of the two.
A building on the hillside next to a valley is primarily made of oedeem, possibly combined with red blood cells by a blood vessel severing. There is oedeem, ontsteking cells, and pus splatter on an ontsteking, such as a steenpuist. There is a holte that is filled with a talc-like substance next to an atheroomcyst. A hutchrat is also a (goedaardige)

Br2 + S2O32- + 5H2O –> 2Br- + 2SO4 + 10H+ + 6e
Answer:
Here's what I get
Explanation:
The ionization energy (I) is the energy required to remove an electron from an atom in the gaseous phase.
You can remove electrons in succession and measure the energies required as I₁, I₂, I₃, etc.
Thus, the removal of two electrons from Cu gives you Cu²⁺.
I found the ionization energies of Cu and used them to create those of Cu²⁺ (see table and graph below).
The electron configuration of Cu²⁺ is
Cu²⁺: 1s² 2s²2p⁶ 3s²3p⁶ 3d⁹
You can remove the nine 3d electrons and then there is a sudden jump from I₉ to I₁₀ as you break into the filled [Ar] configuration.
Similarly, there is big jump from I₁₇ to I₁₈ as you break into the filled [Ne] configuration.
