3 qs

Recently in anatomy class we learned about the endocrine system. We took a test over it last week to test our knowledge on endocrine and reproductive systems. We learned about different hormones and the anatomy of the reproductive system and functions in both male and female. In chemistry class we learned about solids in Lewis structures and when you're more in depth on intermolecular forces and intramolecular forces. I take my test Monday. I hope to get a good grade on this test I am going to study and watch videos in the cover the notes so I know I understand the learning objectives. I am going to go in for help more often more than once a week like I normally do and start to retake my quizzes instead of procrastinating.

3 questions

Recently in my AP class we have learned about  electronegativity and Lewis structures and covalent bonds. We did a lab today where we built structures out of atoms and compare them to our lewis structures that we drew then we figured out the bond shape and angle of each compound. In anatomy we recently learned about the endocrine system and about the different hormones and glands and where they are located and anatomical structure and physiology. What I'm about to do next is going during lunch to practice my stoich and equation solving skills. Hopefully I'll just be able to let it clicked in my head and quit making mistakes on my test in the free response.

Pepper and Soap Explore

What are the different intermolecular forces?
There are four types of intermolecular forces there is ionic forces, dipole forces, hydrogen bonding, and induced dipole forces. Ionic forces hold ions together in ionic solids and are electrostatic forces. Opposite charges attract each other they are the strongest intermolecular force. Dipole forces are polar covalent molecules and are sometimes described as dipoles meaning that the molecule has two poles. One end of the pool has a partial positive charge while the other end has a partial negative charge. They will orient themselves so that the opposite charges attract principle operate effectively. Hydrogen bonding is the attractive force between the hydrogen attached to an electronegative atom of one molecule and the end electronegative atom of the different molecule, usually its oxygen nitrogen or fluorine. The hydrogen is partially positive and attracted to the partially negative charge on the oxygen or nitrogen. Induced dipole forces are forces between essentially nonpolar molecules which is the weakest of all intermolecular forces these temporary dipoles attract or repel the electron clouds of nearby nonpolar molecules.
What intermolecular force does water experience?
Water experiences hydrogen bonding. The hydrogen has a very low electronegativity resulting in the oxygen atoms having greater affinity to the covalent shared electrons this makes the molecule extremely polar so the molecules stick together more.
What intermolecular force does soap seem to have?
Soap is different from water. It is nonpolar because water is polar this was observed when the pepper spread once the soap was dropped in the water. Some type of component that this soap had is nonpolar which reacted with the water which called the repeling of the pepper. After a little while the soap dissolved in spread into the water . Does soap acts as a phospholipid bilayer.
What happened when the soap was added to the pepper water? Why?
When the soap was added to the pepper water the pepper spread to the outside of the cup making it clear center of the water. This is because the soap and water has different intermolecular forces the water is polar and the soap is non polar. The pepper was used to show the repelling of the nonpolar vs polar.
