C. Ca and Br because they're metals and nonmetals
Answer : The value of ΔG expressed in terms of F is, -1 F
Explanation :
First we have to calculate the standard electrode potential of the cell.

or,


Now we have to calculate the standard cell potential.
Formula used :

where,
= Gibbs free energy = ?
n = number of electrons = 2
F = Faraday constant
= standard e.m.f of cell = +0.5 V
Now put all the given values in this formula, we get the Gibbs free energy.


Therefore, the value of ΔG expressed in terms of F is, -1 F
Sorry I skate and usually the smaller wheel rolls faster. Try C. then It's like longboard wheels they roll pretty fast.
Answer:
first option is not true
Explanation:
1 mole = 6.02 × 10²³ particles
C3H8 has 1 mole, so has 6.02 × 10²³ particles
5O2 has 5 moles so 5 × 6.02 × 10²³ = 3.01 × 10²⁴ particles
3CO2 has 3 moles so 3 × 6.02 × 10²³ = 1.806 × 10²⁴ particles
4H2O has 4 moles so 4 × 6.02 × 10²³ = 2.408 × 10²⁴ particles
