Hey there you see ethonol i beliive is a corn based fuel and scientists are saying that it is more healthy for are invirment but not 100% green.however this fuel is not a renewable resource it is still widely abundent because we have corn felids. but i think it is not the smartest investment because if we have a big storm or cropos wont grow anymor than we would not have cars therfore limiting transportationn which setting a huge deppresion. gkad you asked i hads something simmilar to this on my ssvec assignment
Silicon is the second most abundant element in the Earth´s crust and makes up around 27% of it.
Answer:
Yes Both A) KCL and D) HCL are correct...
Answer:
a. Minimum 1.70 V
b. There is no maximum.
Explanation:
We can solve this question by remembering that the cell potential is given by the formula
ε⁰ cell = ε⁰ reduction - ε⁰ oxidation
Now the problem states the cell must provide at least 0.9 V and that the reduction potential of the oxidized species 0.80 V, thus
ε⁰ reduction - ε⁰ oxidation ≥ ε⁰ cell
Since ε⁰ oxidation is by definition the negative of ε⁰ reduction , we have
ε⁰ reduction - ( 0.80 V ) ≥ 0.90 V
⇒ ε⁰ reduction ≥ 1.70 V
Therefore,
(a) The minimum standard reduction potential is 1.70 V
(b) There is no maximum standard reduction potential since it is stated in the question that we want to have a cell that provides at leat 0.9 V
