The question is below
pogonyaev
The reaction that has the greatest tendency to be reversed in an spontaneous redox reaction is that whose forward standard reduction potential is the lowest (mos negative) one because that means that the reversed reaction will have the highest (most positive) standard reduction potential.

So, the answer is Cr(3+) + 3e-    ---> Cr(s) with Eo = -0.91 V, whose reversed reaction is Cr(s) - 3e-         ---> Cr (3+) with Eo = +0.91 V.

Answer: the second option Cr(3+) + 3e-    ---> Cr(s)  Eo = -0.91 V

A process uses 63,400 SCF/h of natural gas. What is the annual cost of natural gas used in the process?
artcher [175]

Explanation:

It is known that 1 SCF produces approximately 1000 Btu of thermal energy.

As it is not mentioned for how many hours the gas is used in this process. Therefore, we assume that the total number of hours natural gas used in this process are as follows.

        365 \times 24 = 8760 hours

Now, we will calculate the annual cost of natural gas used in the process as follows.

               8760 \times 63400

              = 555384000 SCF

Hence, annual cost of natural gas used in this process = loss of thermal energy

This will be equal to,  555384000 \times 1000

                           = 555,384,000,000 BTU

Thus, we can conclude that the annual cost of natural gas used in the process is 555,384,000,000 BTU.
