- The second law of thermodynamics states that the total entropy of an isolated system can never decrease over time.
- it talks about entropy and as we have discussed, 'entropy dictates whether or not a process or a reaction is going to be spontaneous.
- The second law states that isolated systems gravitate towards thermodynamic equilibrium, also known as a state of maximum entropy, or disorder;

6. Write down the 2nd Law equation for each axis separately:
6. Write down the 2nd Law equation for each axis separately:a. Write down, in two columns: x-axis; y-axisb. Write down the sum of all the forces, or components of forces, that act on each axis, on their corresponding column. Mind the sign of the forces, relative to the positive and negative directions of the axes you chose.c. For each axis, if the system is static in that axis, the net force (which you have just written) is equal to zero....

Write down the chemical equation for the 2nd ionization (IE2)
energy for calcium. Follow the instructions below:
Calculate IE2 for calcium using the data listed below. For each data item, write down the chemical equation associated with the process (i.e., that defines the process) - making sure to indicate all phases. In order to show your work, demonstrate, using Hess' law, how you came up with the Born-Haber cycle that lead to the net chemical equation for the IE2 of...

6. Creating a bar graph and Benford's Law Aa Aa Here's an interesting exercise: Write down all the numbers you see on the front page of your college newspaper (excluding the page number). Calculate the proportion of numbers beginning with 1 and the proportion of numbers beginning with 4. Which proportion is greater? Your intuition may suggest that you are equally likely to find both kinds of numbers, so the proportions should be roughly the same. However, more often than...
