Answer: as you add the base it added some PH. The Ph lever of white vinegar is2.4 - 3.4
The concentration of hydronium ion will decrease, and hydroxide ion will increase when a base is added to a white vinegar.
What is pH?pH is the measure scale of how acidic and basic the solution is.
The acid has low pH value and a base has high pH.
When a solution is basic, more hydroxide ion are present and when a solution is acidic, more hydronium ion are present.
Neutral solution will have equal amount of H+ ion and OH- ions.
A buffer neutralizes the pH of any solution.
Thus, the concentration of hydroxide ion will increase and the concentration of hydronium ion will decrease when a base is added to a white vinegar.

Explain: How does pH vary with hydronium ion and hydroxide ion concentrations in water?
Answer:
pH level varies in water for hydronium and hydroxyl ions. pH level is directly proportional to oo hydroxyl ions where as inversely proportional to the hydronium ions.
Explanation:
Answer:
pH is measured with the pH scale which is also known as universal indicator which is the colour combination of different acid base indicators it will indicate the pH level by different colour coding.
pH level varies in water for hydronium and hydroxyl ions.
pH level is directly proportional to oo hydroxyl ions where as inversely proportional to the hydronium ions.
when the concentration of hydroxyl ion increases PH value also increases but when the concentration of hydronium ion increases PH value decreases.
we can say that in this way PH value is related to hydronium and hydroxyl ions in water.

What makes a material dense if we are calculating the Speed of light in thousand miles per second.
Answer: Velocity
Explanation:
The density of a material affects the speed that a wave will be transmitted through it. In general, the denser the transparent material, the more slowly light travels through it. Glass is denser than air, so a light ray passing from air into glass slows down.
Answer:
C is most dense i think lol

why did Mendel become decide to become a teacher?
Answer:
he decided to become a teacher because he studied expertise and wanted to teach about early life
Explanation:
Answer:
While Charles Darwin's "The Origin of Species" was published in November 1859, a monastic priest and teacher named Gregor Mendel was in his third year experimenting with pea plants. His final results demonstrated principles of heredity that would eventually evolve into the new disciplines of genetics and molecular biology. His work not only helped solve the mysteries of diseases such as cystic fibrosis, Tay-Sachs disease, sickle cell disease, and hemophilia, it also and lay the foundation for the Human Genome Project.
Explanation:
( 15 points to whoever replies quickest no links pls ) a farmer has used a fertiliser containing ammonium nitrate, potassium nitrate and ammonium sulphate on his fields but some may have leached into a nearby river. If a sample of river water was tested, what colour would the flame be if there was fertiliser contamination
If water of the river was tested there would be orange color flame.
What is fertilizer?Millions of tons of air, natural gas, and mined ores are transformed into plant nutrition products based on the three crucial nutrients nitrogen, phosphorus, and potassium by the fertilizer industry.
The process begins by combining nitrogen from the air with hydrogen from natural gas at high temperature and pressure to produce ammonia, which is then used to make nitrogen-based fertilizers, the largest product category. Natural gas is used as a raw material for about 60% of the time, while the remaining 40% is used to power the synthesis process.
The nitric acid created from the ammonia is combined with it to create nitrate fertilizers like ammonium nitrate (AN). Urea can also be made by combining ammonia with liquid carbon dioxide. To create UAN (urea ammonium nitrate) solution, both of these products can be combined with water.
Therefore, If water of the river was tested there would be orange color flame.
