Hard water contains certain minerals that can be rougher on the skin and hair.
Answer:
a) 1,737 kJ
b) -1,93 kJ
Explanation:
The standard free energy change (ΔG) can be determined using:
ΔG = -nFE
a) For the reaction:
Fumarate²⁻ + CoQH₂ ⇄ succinate²⁻ + CoQ
The transferred electrons are 2, As E=-0,009V:
ΔG = -2×96,5kJ/molV×-0,009V
<em>ΔG = 1,737 kJ</em>
b) For the reaction:
cytc1 (Fe²⁺) + cytc (Fe³⁺) ⇄ cytc1 (Fe³⁺) + cytc (Fe²⁺)
The transferred electron is n=1 and E=0,02V:
ΔG = -1×96,5kJ/molV×0,02V
<em>ΔG = -1,93 kJ</em>

Answer:
ΔEN CO = 1.0
Explanation:
To calculate the electronegativity difference, we have to substract the element which has the highest EN to the other, that has a low value.
For this case EN from O - EN from C
Electronegativity is a property of the periodic table that increases diagonally, where Fr and Rb are the elements of less EN while F is the most electronegative element, with a value of 4. This is because F is an element with a high ionization energy and a negative electronic affinity.
ΔEN CO = 3.5 - 2.5 = 1.0
Electronegativity (EN) describes the ability of an atom to compete for
electrons with other atoms to which it is attached.
