Answer:
The answer to your question is P1 = 1.4 atm
Explanation:
Data
Volume 1 = V1 = 735 ml
Pressure 1 = P1 = ?
Volume 2 = V2 = 1286 ml
Pressure 2 = P2 = 0.8 atm
Process
To solve this problem use Boyle's law.
P1V1 = P2V2
-Solve for P1
P1 = P2V2 / V1
-Substitution
P1 = (0.8 x 1286) / 735
-Simplification
P1 = 1028.8 / 735
-Result
P1 = 1.4 atm
Answer:
We expect the enthalpies of combustion of two isomers to be different.
The molecular formular of the two molecules are very similar.
So the balanced chemical equation for the two combustion reactions are the same.
Explanation:
In calculation of the combustion enthalpiesfrom the isomers of the products and reactant.
The difference will be in the standard enthalpies of formation of the two combustion products.
The rod-shaped n- octane has vibrational and rotational motion possible more than the almost spherical neoprene.
Magic number is any number in electron shells that suggest stability. It corresponds to total number of electrons in filled electron shells.
If an electron is having magic number, then it forms stable bonds.
Explanation:
The magic numbers are 2,10,18,36,54, 86 and 126. This refers to the total number of electrons that an electron can have when it is completely filled.
Atomic nuclei which carries either of these nucleons have high binding energy as compared to others. Hence, they have high stability. Bonds in such elements are more strong.
Radioactive decay of such elements is very slow.
Eugene Winger coined the term "magic number".
