Answer:
The pH scale has been drawn below.
Explanation:
pH sacle may be defined as the scale that determines the pH of acids and bases. 0 represent the neutral compounds. The compounds that pH less than 7 acts as acid whereas the compounds that have pH greater than 7 acts as base.
Here, water is neutral, Hydrochloric acid (HCl) is acidic and sodium hydroxide (NaOH) acts as base.
Water, hydrochloric acid, and sodium hydroxide can be placed on the pH scale as follows:
Water: Water is considered neutral and has a pH of 7. It falls in the middle of the pH scale.
Hydrochloric acid: Hydrochloric acid is a strong acid and is highly acidic. It has a pH below 7. The exact pH value of hydrochloric acid may vary depending on its concentration, but it typically falls within the range of 0 to 2.
Sodium hydroxide: Sodium hydroxide is a strong base and is highly alkaline. It has a pH above 7. Again, the specific pH value of sodium hydroxide can vary based on its concentration, but it typically falls within the range of 12 to 14.
So, on the pH scale, water would be placed at pH 7 (neutral), hydrochloric acid would be placed below pH 7 (acidic), and sodium hydroxide would be placed above pH 7 (alkaline).

Answer:
Dinosaurs are the extinct organisms that belong to the class reptilia. Dinosaurs are the most advanced and bulkier reptiles at the history time and they were overspecialized in their environment.
The dinosaurs extinct rapidly due to the change in the external conditions and the volcanic eruptions that occur at the dinosaurs time. The recent searcher claims that asteroid impact and massive volcanic eruption leads to the dinosaur extinction. The fossil evidence and the presence of the specific basalt and other chemicals are found in the volcanoes and in the asteroid.
