Does corrosion occur when iron nail is in salt water

Chemistry
1 answer:
yarga [219]3 years ago
5 0

Answer:

Yes

Explanation:

: The corrosion of iron indicates a chemical change in the metal. ... Where salt is present, electrochemical corrosion occurs, and the protective oxide film does not form, thus the corrosion (buildup of rust) continues unchecked. Your iron nail will indeed rust more quickly and severely in salt water.

A cell has a standard emf of + 0.135 v at 298 k. part a what is the value of the equilibrium constant for the cell reaction if n
Irina-Kira [14]
To look for the value of the equilibrium constant for the cell where n=1, it is computed by:
Eo = RT / nF * ln(K) 
(Eo * nF) /RT = ln(K) 
(0.135 * 1mol* e- * 9.65E4C/mol*e) / (8.314J / molK * 298K) = ln(K) 
10.52 = lnK 
e^10.52 = e ^ lnK 
K = e ^263/25
K = 37049.12 is the answer.

A/1 * B/C = D
Anit [1.1K]

Answer: 0.64 Moles of Propane

Explanation:

Data:

        Moles of Carbon  =  1.5 mol

        Conversion factor  =  7 mol C produces = 3 mol of Propane

Solution:

            As we know,

               7 moles of Carbon produces =  3 moles of Propane

Then,

           1.5 moles of Carbon will produce  =  X moles of Propane

Solving for X,

                    X =  (1.5 moles × 3 moles) ÷ 7 moles

                    X  =  0.6428571 moles of Propane

Or rounded to two significant figures,

                    X =  0.64 Moles of Propane
