( 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.

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.

What happens to salt water and fresh water when you try to mix them.
Answer:
the lighter fresh water rises up and over the salt water
Explanation:
this is because the salt water is denser
Answer:
When trying to mix fresh/salt water it leads to variable and dynamic chemical conditions, especially salinity because fresh water flowing into the estuary is less salty and less dense than water from the ocean, it often floats on top of the heavier seawater.
