Parts of respiratory system:
Nose and Nasal Cavity, mouth, Pharynx, Larynx, Trachea, Bronchi and Bronchioles, Lungs and Muscles of Respiration.
Respiratory system function:
Your respiratory system is the network of organs and tissues that help you breathe. This system helps your body absorb oxygen from the air so your organs can work. It also cleans waste gases, such as carbon dioxide, from your blood.
Alveoli:
Alveoli are tiny sacs of air in your lungs that take up the oxygen you breathe and keep it going. The alveoli ventilate, diffuse and peruse in your lungs.
There are two possible products from this elimination:
-2,3-dimethylbut-1-ene
-2,3-dimethylbut-2-ene
As the base is relatively unhindered, the reaction will form the Saytzeff product as the major product. The Saytzeff product is the most substituted alkene which is more stable due to hyperconjugation. In this reaction the Saytzeff product is 2,3-dimethylbut-2-ene.
Answer:
ok 3 = 9 15 i got 15 so what
Explanation:
HALOGENS have 7 electrons in their final shell regardless if the total number of atoms. These 7 electrons would be shared between the 's' and 'p' orbital in the form
ns² np⁵ (the same as the question). Attached is a table that highlights the fact that halogens have the same form in terms of the valence electrons.
Could’ve reacted with water as alkali metals are very reactive to water.
