Answer:
Sulfur, phosphorus, silicon, and chlorine are common examples of elements that form an expanded octet.
Explanation:
Phosphorus pentachloride (PCl5) and sulfur hexafluoride (SF6) are examples of molecules that deviate from the octet rule by having more than 8 electrons around the central atom
Answer: Option (d) is the correct answer.
Explanation:
In solids, molecules are held together by strong intermolecular forces of attraction. As a result, they are unable to move from their initial position and can only vibrate at their mean position.
Hence, a solid has definite shape and volume. Solids cannot be compressed.
Whereas in plasma, molecules are hot ionized which include positively charged ions and negatively charged electrons. They collide much more rapidly with each other and are widely spreaded out.
Therefore, they occupy the volume of container in which they are placed. Plasma can be compressed.
Thus, we can conclude that substance X is a solid and substance Y is a plasma.
Answer:
<u>The Answer is (B) A car get rusty over the course of few years</u>Explanation:
<u>Explanation:</u>
- <u>Oxidation </u>refers to the process of loss of electrons by a molecule,atom or ion during a chemical reaction.The process which is just the opposite of oxidation is reduction,it occurs when their is gain of electrons .
- <u>When iron reacts with the oxygen it forms a chemical know as Rust.In this case iron has lost some electrons and the oxygen has gained some electrons</u>

Fusion releases less energy than fission
fusion most commonly combines heavy isotopes of hydrogen into helium.
Explanation:
Nuclear fusion is a form of reaction that involves the combination of two light nuclei to form one that is heavier in mass.
The other form is nuclear fission which is the splitting of heavier nuclei either spontaneously or when bombarded with other nuclei.
- Nuclear fusion reactions in the core of stars powers the universe.
- The reactions produces a huge amount of energy of a greater and massive order than fission reaction.
- Small nuclei are involved in nuclear fusion and not the large ones.
- Nuclear fusion degenerates into series of chain reactions that are extremely difficult to control.
