It's the balance of chemical equation.
The activities that involves a chemist would be activities that involves quantification and qualification of a product. One that involves chemical reactions and the use of chemical substances. Hope this answers the question. Have a nice day.
The answer c) A- Cell membrane because it selects what molecules enter/exit the cell
212 degrees Fahrenheit is the temperature at which water boils.
Answer:

Explanation:
Hello!
In this case, for the given reaction, we can write the equation to compute the entropy change as shown below:

Letting:

We obtain the entropy change per mole of Fe2O3(s):
Finally, the total entropy change when 1.73 moles of Fe2O3(s) react turns out:
