( 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
Answers
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.

Describe the concentration of hydronium ions and hydroxide ions when a base is added slowly to a white vinegar solution. The pH of white vinegar is 3.1.
Answers
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?
Answers
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.

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.

c. You have a series circuit with a current of 6 amps and three resistors on it, with resistances of 10 ohms, 5 ohms, and 6 ohms, respectively. What is the voltage of this circuit? Show your calculation.
Answers
b. The same. In a series circuit, the voltage is split between the resistors. Since the resistors have the same resistance, the voltage across both of them will be the same.
c. V = IR (Ohm’s law)
I = 6 amps
R = 10 + 5 + 6 = 21 ohms (because in a series circuit, the total resistance is just the sum of all of the resistors’ resistances)
V = (6)(21) = 126 volts

Answer:
1. B. environment
2. A. true
Explanation:
If a trait varies greatly within a pair of identical twins, it is most likely influenced by the environment. Genetics and the environment both are responsible for human development.
What is Genetics?Genetics can be described as the study of genetic variation, genes, and heredity in organisms. It is a branch in biology because heredity is vital to organisms' evolution.
Trait and molecular inheritance mechanisms of genes are still primary principles of genetics and have expanded to study the function and behavior of genes.
Genetics has a number of subfields, including molecular genetics, epigenetics, and population genetics. Living organisms are studied within the broad field span the domains of life such as bacteria, archaea, and eukarya.
Genetic processes work with an organism's environment and experiences to influence behavior and development referred to as nature versus nurture. The extracellular or intracellular environment of a living organism can switch gene transcription on or off.
