pH is an indicator of how acidic or basic a substance is. The pH scale ranges from 0 - 14, with 7 representing neutral. Acids have a pH below 7; bases, a pH greater than 7. Scientists determine the pH of a substance by using an indicator; indicators change color depending on the pH of a substance. Different indicators work at different pH ranges, as seen in the table above. The transition range of an indicator is the range of pH when the indicator changes from its low-pH color to its high-pH color. If the indicator shows a color between the two, then the pH lies somewhere in that transition range. You have been given a liquid that turns pink in phenolphthalein and blue in thymolphthalein. Tests with methyl violet and bromophenol blue resulted in a violet color. Based on your test results, determine which statements regarding the liquid are accurate. Choose ALL that apply.
A. The liquid is a base.
B. The liquid is an acid.
C. The liquid has a pH > than 7.
D. The liquid is an H⁺ donor.
E. The liquid mostly likely contains OH⁻.
The liquid is base. A base is a type of chemical that releases hydroxide (OH-) ions, receives protons, or donates electrons in an aqueous solution.
What are Bases?Bases have a few distinguishing characteristics that can be used to recognize them. They can taste harsh, react with acids to generate salts, have a tendency to be slick to the touch (like soap), and can catalyze some processes.
Arrhenius bases, Bronsted-Lowry bases, and Lewis bases are some examples of bases. The French scientist Louis Lémery coined the term "base" in 1717. Lémery used the term to refer to Paracelsus' alchemical notion of a "matrix" According to Paracelsus, natural salts form when a matrix and a universal acid interact.
Although Lémery may have coined the term "base" first, Guillaume-François Rouelle is generally recognized as the father of modern usage.
Therefore, The liquid is base. A base is a type of chemical that releases hydroxide (OH-) ions, receives protons, or donates electrons in an aqueous solution.

A rearranged; destroyed; gained
B created; destroyed; lost
C rearranged; created; conserved
D created; destroyed; conserved
Answer:
D created; destroyed; conserved
For a chemical reaction in a closed system, mass cannot be created or destroyed. We can say that throughout the reaction, mass is conserved.
What is a closed system?
A closed system is a thermodynamic term. It can also be said as thermodynamic system. In a thermodynamic closed system, there is no exchange of mass or energy with the outer environment.
Thus, the correct option is D. created; destroyed; conserved.

Human Activity
It's important to note that human activity has the greatest impact on the amount and quality of wildlife habitat in many areas of the world. Wildlife habitat can be destroyed or its quality diminished as a result of urban growth, agricultural practices, pollution, or habitat destruction.
People can also have a positive impact on wildlife populations through improvement and protection of habitat or ecosystems. Planting trees and shrubs and providing sources of food and water in individual yards is one way people can help wildlife.

How can a force act directly on an object? Explain.
Answer:
The quantity of force is expressed by the product of mass (m) and acceleration (a). Mathematically the equation can be written as
F = ma
Where,
F= Force
m = mass
a = acceleration
When a force acts on an object the objects the objects have different effects of force. So let us know about the effects of force on an object.
Explanation:
Answer:
Explanation:
An applied force is a force that is applied to an object by a person or another object. If a person is pushing a desk across the room, then there is an applied force acting upon the object.
