They have thier own group because because they have traits or metals and nonmetals
Answer:
the cells start to deteriorate
Explanation:
the lack of oxygen to your body and cells will cause them to break down.
Answer:

Explanation:
The pressure is constant, so we can use Charles' Law to calculate the volume.

Data:
V₁ = 22.4 L; T₁ = 273.15 K
V₂ = ?; T₂ = 136.58 K
Calculations:

Oxygen(O)
Explanation:
Oxygen is the most reactive of all the listed elements. One can determine their reactivities based on the electronegativity values.
- Every element combines with one another to attain stability like the noble gases.
- Electronegativity is the relative ease with which the atoms of elements attracts valence electrons in a chemical bond.
- On the pauling's electronegativities table of elements, carbon is 2.5, oxygen 3.5 and Cl is 3.0
- Oxygen will have the highest reactivity and the most tendency to combine with other atoms.
