Answer:
We will not know immediately
Explanation:
The distance of star Betelgeuse = 325 light years
Therefore, if it where to explode, at the location, we would have a supernovae such that the luminosity of the star multiplies several multiple times
However, due to the distance of Betelgeuse from the Earth, it will take the light of the explosion, 325 years to reach Earth and the explosion as it happens will not be noticed here on Earth immediately
Answer:
Sulphur (IV) Oxide solution
Explanation:
Sulphur (IV) Oxide with the chemical symbol 
is a covalent compound consisting only of nonmetals. In chemistry it is well known that Covalent compounds do not conduct electricity because they have no free electrons and ions.
the ideal gas equation is PV=nRT
where P=pressure
V=Volume
n=no. of moles
R=universal gas constant
T=temperature
The universal gas constant (R) is 0.0821 L*atm/mol*K
a pressure of 746 mmhg =0.98 atm= 1 atm (approx)
T=37 degrees Celsius =37+273=310 K (convert it to Kelvin by adding 273)
V=0.7 L (only getting oxygen, get 21% of 3.3L)
Solution:
(1 atm)(0.7 L)=n(0.0821 L*atm/mol*K)(310 K)
0.7 L*atm=n(25.451 L*atm/mol)
n=0.0275 mole
Answer:
n=0.0275 mole of oxygen in the lungs.
Answer: oxygen, hydrogen, sodium, chlorine, lead, iron. Examples of compounds include water ( or hydrogen oxide ) H2O; and Sodium Chloride, NaCl.
