The chemist is most likely investigating Gay Lussac's law. To study the changes in temperature affect the pressure of the gas when a fixed amount of gas is heated in a sealed glass container. Therefore, option (D) is correct.
What is Gay Lussac's law?Gay-Lussac's law states that when the volume of the gas is kept constant the pressure of a gas is directly proportional to the absolute temperature.
The mathematical expression of Gay Lussca's law can be written as follows:
P/T = k
It can be also represented as the pressure being directly proportional to the temperature of the gas.
P ∝ T (where V volume of gas is constant)
or
[tex]\frac{P_1}{T_1} =\frac{P_2}{T_2}[/tex]
Where P₁ and T₁ are the initial temperature and pressure of the gas. The P₂ and T₂ are the final temperature and pressure of the gas.
As the container is sealed on heating the volume of the gas will not change. On increasing the temperature the molecules of the gas acquire more and more kinetic energy. So the pressure of the gas will increase.
Therefore, the chemist is investing the Gay-Lussac's law by noticing how changes in temperature affect the pressure of the gas.

what is the net cell reaction for the chromium-silver voltaic cell?
Cr(s) → Cr3+(aq) + 3e-Ag+(aq) + e- → Ag(s)
To solve such this we must know the concept of chemical reaction. Therefore, the balanced net cell reaction for the chromium-silver voltaic cell is Cr(s)+3Ag⁺(aq)→Cr³⁺(aq)+3Ag(s)
What is chemical reaction?Chemical reaction is a process in which two or more than two molecules collide in right orientation and energy to form a new chemical compound. The mass of the overall reaction should be conserved. There are so many types of chemical reaction reaction like combination reaction, double displacement reaction. Chromium-silver voltaic is a cell that is used in electrochemistry.
The balanced net cell reaction for the chromium-silver voltaic cell is
Cr(s)+3Ag⁺(aq)→Cr³⁺(aq)+3Ag(s)
Therefore, the balanced net cell reaction for the chromium-silver voltaic cell is

- Explain the relationship between electronic structure and the chemical
properties of an element.
Answer: There is a relationship between the electron configuration of an element and its resulting chemical/physical properties. Atoms of an element like to have a full octet of electrons in their valence shells. ... Other elements need to lose or gain electrons to obtain an octet.

What volume of 0.205 MK2S solution is required to completely react with 185 mL of 0.120 MCo(NO3)2?
Answer:
the balanced equation for the above reaction is as follows;
3NiCl₂ + 2K₃PO₄ ---> Ni₃(PO₄)₂ + 6KCl
stoichiometry of NiCl₂ to K₃PO₄ is 3:2
the number of NiCl₂ moles reacted - 0.0102 mol/L x 0.134 L = 0.00137 mol
according to molar ratio
if 3 mol of NiCl₂ reacts with 2 mol of K₃PO₄
then 0.00137 mol of NiCl₂ reacts with - 2/3 x 0.00137 = 0.000911 mol of K₃PO₄
molarity of given K₃PO₄ solution - 0.205 M
there are 0.205 mol in 1000 mL
therefore volume of 0.000911 mol - 0.000911 mol / 0.205 mol/L = 4.44 mL
volume of K₃PO₄ needed is 4.44 mL

when does cells breakdown a sugar molecule completely to produce chemical energy ATP the cells need to the following materials
Answer:
sugar and carbon dioxide
Explanation:
Chemical energy is stored in the bonds of sugars. When the bonds of a sugar molecule are broken, a burst of energy is released that the cell can use. Cells can release energy in two basic processes: cellular respiration and fermentation. Cellular respiration requires oxygen, but fermenta- tion does not.

How does collision theory relate temperature to the rate of a reaction?
Answer:
Explanation:
The collision theory explains why reactions occur between atoms, ions, and molecules. With the increase in temperature, there is an increase in the number of collisions. Increasing the concentration of a reactant increases the frequency of collisions between reactants and will, therefore, increase the reaction rate.
