Aluminium + Dioxygen = Ruby
a. lawn fertilizer runoff
Pollution as a result of lawn fertilizer runoff would be difficult to track and regulate due to the possible breadth of the area affected. Toxins can be spread throughout the land area as well as be carried downstream if near a water source. Sewer systems, rivers, lakes, ponds, etc. can all be negatively affected by lawn fertilizer runoff. Irrigation or rain water can carry toxins for many miles before the effects are detected. Tracing the source of the toxins would be difficult, especially in a highly populated area.
Answer:
2,3-dimethylheptane.
CH₃ - CH - CH-CH₂-CH₂-CH₂-CH₂
| |
CH₃ CH₃
Explanation:
Hello there!
In this case, according to the given instructions, it is possible to draw the organic chemical structure by connecting seven carbon atoms along the parent chain with two methyl substituents at the second and third carbon atoms; thus, the resulting structure is:
CH₃ - CH - CH-CH₂-CH₂-CH₂-CH₂
| |
CH₃ CH₃
Furthermore, the name would be 2,3-dimethylheptane according to the IUPAC rules for nomenclature.

There are 115 protons in the element 115 and due to the large number of protons, the element does not exist in nature.
Also, the element can not be isolated in nature that is IUPAC had to require an independent confirmation of the element.
<h3>What is element 115?</h3>
We know that the periodic table is an arrangement of the atoms in order of increasing atomic number. We know that the larger the atomic number of the element, the less likely that the element would be stable in nature. The element that have been named 115 is called Moscovium and was discovered in Moscow as a product of a radioactive experiment. The number of protons in element 115 is 115 protons
Generally, the element number 115 does not exist in nature because if the proton number in an element exceeds 82, the repulsion between the protons would make it almost impossible for the nucleus to be a stable nucleus.
The reason why IUPAC had to request an independent confirmation of the element is because it does not exist in nature.
