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)
Explanation:
byju's ig. Cause it gives a proper concept
Answer:
2. 100 times more hydroxide ions,
Explanation:
Acidity and alkalinity are measured with a logarithmic scale called pH. Each one-unit change in the pH scale corresponds to a ten-fold change in hydrogen ion concentration. Therefore, a 1.0 liter aqueous solution with a pH of 5.0 contains 100 times more hydronium ions than a 1.0 liter aqueous solution with a pH of 7.0
Answer:
blended is better than synthetic fibre. because blended fabrics have quality of synthetic and natural fibres so they are more better than fabrics. For example terrycot. Blended Fibres are considered better than individual synthetic fibres because they show the advantages of 2 or more fibres.
Answer:
Explanation:
By observing chemical reactions, we are able to understand and explain how the natural world works. Chemical reactions turn food into fuel for your body, make fireworks explode, cause food to change when it is cooked, make soap remove grime, and much more.
