The formation of Fossil Fuels.
The fossil fuels such as oil originate mostly from aquatic organism and are extracted on oil rigs located in oceans and seas. Most of the oil is procured this way.
Answer:
Element with 6s subshell
Explanation:
Reactivity of an element depends on the electronic configuration and position of element in the periodic table as reactivity increases as we go down the periodic table.
This is so because number of shell increases as move down the periodic table and the last electron is further away from the nucleus.
Element with 6s subshell is the largest among 3s and 4s subshell and has more number of shells so it will react more than 3s and 4s subshell.
Hence, the correct answer is "Element with 6s subshell".
When edible oils are idle and stored for a long amount of time, they undergo oxidation due to the exposure to oxygen. This oxidation causes rancidity in oils.
Answer:
<em>D</em><em>.</em><em>They have properties similar to those of their component elements.</em><em> </em>
Explanation:
When elements are joined, the atoms lose their individual properties and have different properties from the elements they are made of .
