Answer:
Hello your question has some missing data attached below is the missing data ( Note: the PH in the attached question is 3.2 but the PH value I used in the solution = 3.1 as requested in the initial question )
answer : 0.41 volts
Explanation:
Given data :
[ Fe²⁺ ] = 1.3 M
[ Fe³⁺ ] = 0.010 M
[ H⁺ ] = 10^3.1
O2 = 0.20 atm
E⁰cell = 0.46 volts
temperature = 25°C ( room temperature )
<u>Calculate the voltage of this ( 3 -cell battery ) </u>
we can apply the relation below
E = E⁰cell - ( 0.0591 / n )*Log Q
= 0.46 - ( 0.0591 / 4 )*Log [ (0.01)^4 / (1.3)^4 * (10^3.1)^4 * 0.2 ]
= 0.4120 Volts

<em>Note : Q is determined from the equation attached to the question </em>
Answer:
Its the first one. The cells are arranged for structure.
Explanation:
Animal cells do not need to maintain a shape since out bodies do it for us. Plant cells need something for structure.
11.2L/22.4L (STP value) x 1 mol of CH4 x 16.04 g of CH4 = 8.2 g
