Answer:
B
Explanation:
B It’s a physical change because the water and the salt kept their original properties.
A major factor in how the periodic table<span> is organized is the configuration of each </span>element's<span> valence electrons. Because </span>elements<span> in each family have the same number of valence electrons, they tend to have several similar </span>characteristics<span>.</span>
Answer:
Chlorine-36 undergoes β-decay.
Explanation:
Cl-36 is radioactive. It emits an electron ( a β-particle) to become more stable and forms Ar-36.
The nuclear equation is

When you heat up the matter, it gains energy and the bonds are broken. Then it will make solid become liquid
The law which this chemist is most likely investigating heating a fixed amount of gas in a sealed glass container is: Gay Lussac’s law.
Gay Lussac's law states that when the volume of an ideal amount of gas is held (kept) constant, the pressure of the gas is directly proportional to the absolute (Kelvin) temperature of the gas.
Mathematically, Gay Lussac's law is calculated by using the formula;

<u>Where:</u>
is the original pressure.
is the final pressure.
is the original temperature.
is the final temperature.
In conclusion, the chemist is most likely investigating how changes in temperature affect the pressure of the gas by heating a fixed amount in a sealed glass container in accordance with Gay Lussac's law.
