Calculate the standard free-energy change at 25 ∘C for the following reaction:
lianna [129]

Answer:

Standard free-energy change at 25^{0}\textrm{C} is -3.80\times 10^{2}kJ/mol

Explanation:

Oxidation: Mg(s)-2e^{-}\rightarrow Mg^{2+}(aq.)

Reduction: Fe^{2+}(aq.)+2e^{-}\rightarrow Fe(s)

--------------------------------------------------------------------------------------

Overall: Mg(s)+Fe^{2+}(aq.)\rightarrow Mg^{2+}(aq.)+Fe(s)

Standard cell potential, E_{cell}^{0}=E_{Fe^{2+}\mid Fe}^{0}-E_{Mg^{2+}\mid Mg}^{0}

So, E_{cell}^{0}=(-0.41V)-(-2.38V)=1.97V

We know, standard free energy change at 25^{0}\textrm{C}(\Delta G^{0}): \Delta G^{0}=-nFE_{cell}^{0}

where, n is number of electron exchanged during cell reaction, 1F equal to 96500 C/mol

Here n = 2

So, \Delta G^{0}=-(2)\times (96500C/mol)\times (1.97V)=-380210J/mol=-380.21kJ/mol=-3.80\times 10^{2}kJ/mol

A 50 kg cart has 324 kg•m/s of<br> momentum. How fast is the cart going?
PilotLPTM [1.2K]

Answer: 6.48m/s

Explanation:

From the question given, we obtained the following:

M = 50 kg

Velocity =?

Momentum = 324 kg•m/s

Momentum = Mass x Velocity

Velocity = momentum /Mass

Velocity = 324 / 50

Velocity = 6.48m/s

What is the molarity of a solution that contains 200. 0 g of lithium chloride in 450 mL? molar mass of chloride= 42. 394g/mol
alisha [4.7K]

Explanation:

Sol. 450 ml there is LiCl 200 g

Sol. 1000 ml there is LiCl 200/450×1000

= 444.44 g

Molar = g/molar mass = 444.44/42.394 = 10.48 M
