Find ∆G for a cell whose potential is +0.24 V with 4 moles of electrons exchanged.
Setler [38]
We need to use the following formula
ΔG= -nF E_{cell}

E_{cell}= 0.24V
n= 4 moles
F= constant= 96500C/mol

let's plug in the values.

ΔG= -(4)(96500)(0.24)= -92640 J or -92.6 kJ

3.75 g of an unknown gas at 59 °C and 1.00 atm is stored in a 1.35-L flask. What is the molar mass of the gas?
MAXImum [283]
You need to find moles of the gas, so you would use the ideal gas law:
PV=nRT
Pressure
Volume
n=moles
R= gas constant
Tenperature in Kelvin
n= PV/RT
(1.00atm)(1.35L)/(.08206)(332K) = 0.050mol
Molar mass is grams per mole, so
(3.75g/.050mol) = 75g/mol

An atom in the ground state contains a total of 5 electrons 5 protons and 5 neutrons. Which Lewis electron-dot diagram represent
Luba_88 [7]
I don't know if you didn't gave a picture choice or if i didn't get the picture.
But lets call this atom A. Electron dot formula doesn't require Neutron and Protons, its main concern is valance elections.

So atom A has 5 electrons which means 2,3 it has 3 valance electrons. Its dot formula will become
:A.

I hope this helped.

Which measure of a gas does the expression
Usimov [2.4K]

Answer:

A. volume

Explanation:

Generally the equation for the  ideal gas  is mathematically given as  

PV=nRT

Where  

P=pressure  

V=volume  

R=gas constant  

n=Number of Moles  

T=Temperature

 

Therefore  

V=nRT/P  

Option A
