The isotope with atomic number Z = 29 and atomic mass A = 65 is for Copper and its isotopic notation is 65Cu.
The isotope with atomic number Z = 29 and atomic mass A = 65 is for the element Copper (Cu). To write this in isotopic notation, you represent it as 65Cu. Here, the atomic number Z (number of protons) is represented by Cu and the mass number A (number of protons + neutrons) is represented by the superscript number 65. Thus, the isotope notation symbol for this is is 65Cu.

Explanation:
A solution with pH less than 7 will be acidic in nature and it will change color of blue litmus into red.
For example, HCl is a strong acid as it dissociates to give hydrogen ions and chlorine ions.
A solution with pH more than 7 will be basic in nature and it will change color of red litmus into blue.
A solution with pH equal to 7 will be neutral in nature and it will not change the color any litmus paper.
Thus, we can conclude that in a 0.01 M solution of HCl, litmus will be red.

Alchemy made contributions to the development of chemistry through advancements in manipulating matter, discovering the law of conservation of matter, and contributing to the understanding of atoms and the periodic table.
Alchemy made some contributions to the development of chemistry. Although it was not scientific by modern standards, alchemists made progress in manipulating matter and exploring the properties of substances. One example of an alchemist's contribution is the discovery of the law of conservation of matter by Antoine Lavoisier, often regarded as the father of modern chemistry. Lavoisier's work with gases also changed chemistry from a qualitative to a quantitative science and laid the groundwork for further study. Additionally, alchemists played a role in developing the concept of atoms and the periodic table, which are fundamental in chemistry.
