An extensive property is a property that deals with the amount of a substance. An extensive property of marker ink would be the volume of the ink in the pen.
An intensive property is a property about the type of substance you're looking at. So, an intensive property of marker ink would be the color of the ink.

Answer:
Explanation:
Hello,
In this case, since the density is defined as the degree of compactness a substance has and is mathematically defined as:
Thus, for this problem, as we know both the density and mass of water we can compute the volume as shown below:
Best regards.
Answer:
We add A Hydrogen
Explanation:
When we have a half-reaction in an acidic media usually we add (H+) hydrogen plus or protons to the reaction to balance in both sides of the reaction the amount of hydrogen.
After this step the next one is equilibrate the charges (e-) and finally we add the two half-reactions to write a short version
Through homogeneous co-precipitation and traditional solid-state calcining, a red long persistent phosphor of -Zn3(PO4)2: Mn2+, Mg2+ was created.
<h3>Effects of mg2 on improving luminous performance for a red long-lasting phosphor, -zn3 (po4) 2: mn2</h3>
- X-ray diffractions, scanning electron microscopes, X-ray photoelectron spectroscopies, decay curves, and thermoluminescence spectra were used to corroborate the crystalline structures and characteristics of the materials.
- The phase transition of Zn3(PO4)2:Mn2+ from to as well as the enhancement of the crystallinity of phosphors will be caused by the dopant of Mg2+, according to the XRD results.
- A noticeable peak at 620 nm in the photoluminescence emission spectrum of the red -Zn3(PO4)2: Mn2+, Mg2+ phosphor is due to the Mn2+ ion's 4T1g-6A1g transition.
- The addition of Mg2+ as a dopant can significantly improve the luminous characteristics of -Zn3(PO4)2: Mn2+.
- For the discussion of intrinsic flaws, TL curves are used. The suggested persistent luminescence operating mechanism
