Answer:
1,372,800,000 Feet
Explanation:
1 Mile = 5280 Feet
260,000 Miles = 5280 × 260,000 Feet
260,000 Miles = 1,372,800,000 Feet
Answer:
1.20 V
Explanation:
Here Pb undergoes oxidation by loss of electrons, thus act as anode. Bromine undergoes reduction by gain of electrons and thus act as cathode.
Where both 
are standard reduction potentials.
Given,
![E^0_{[Pb^{2+}/Pb]}= -0.13\ V](https://tex.z-dn.net/?f=E%5E0_%7B%5BPb%5E%7B2%2B%7D%2FPb%5D%7D%3D%20-0.13%5C%20V)
![E^0_{[Br_2/Br^{-}]}=+1.07\ V](https://tex.z-dn.net/?f=E%5E0_%7B%5BBr_2%2FBr%5E%7B-%7D%5D%7D%3D%2B1.07%5C%20V)
![E^0=E^0_{[Br_2/Br^{-}]}- E^0_{[Pb^{2+}/Pb]}](https://tex.z-dn.net/?f=E%5E0%3DE%5E0_%7B%5BBr_2%2FBr%5E%7B-%7D%5D%7D-%20E%5E0_%7B%5BPb%5E%7B2%2B%7D%2FPb%5D%7D)
The building block that makes up all matter in the universe is atoms.
Hope that helps you:)
Explanation:
In general, atoms are most stable, least reactive, when their outermost electron shell is full. Most of the elements important in biology need eight electrons in their outermost shell in order to be stable, and this rule of thumb is known as the octet rule.
