Chapter 5, Problem 44E
Interpretation Introduction
Interpretation:
Usefulness of Lewis theory over other theories to explain
Concept Introduction:
A scientific method consists of making observations and formulating a hypothesis. This is followed by making testable predictions that are tested over and over, to state whether or not the hypothesis is correct.
A scientific theory is based on one or more hypotheses supported by repeated testing. A theory describes why and how something happens. In many cases, one theory forms the basis on which other theories can be built. Thus, theories can evolve.

Look at the structure of a soap molecule, and explain what happened when you added soap to your oily hands and put your hands under the water for the solubility lab. Why could you wash the oil off your hands with soap and water? You should use chemistry concepts including structure, polarity, and intermolecular forces to explain your answer.
attached is the lewis structure of a basic soap molecule. There are covalent bonds between all carbons, hydrogens, and oxygens. However, there is an ionic bond between oxygen and sodium ions.
Compare the chemical structure of compound A with that of compound B. Answer it in a detailed way. Thank You.

The number of covalent bonds an atom can form relates to the number of electrons it can share and still result in a neutral molecule.

How is it similar?arrow_forwardSome theories of aging suggest that free radicals cause certain diseases and perhaps aging in general. As you know from the Lewis model, such molecules are not chemically stable and will quickly react with other molecules. According to some theories, free radicals may attack molecules within the cell, such as DNA, changing them and causing cancer or other diseases. Free radicals may also attack molecules on the surfaces of cells, making them appear foreign to the body’s immune system. The immune system then attacks the cells and destroys them, weakening the body. Draw Lewis structures for the free radicals implicated in this theory of aging, which are given here. a. O2 -b. O- c.

Bond energy is the energy required to break one mole of the bond in the gas phase. Since it takes energy to break a bond, bond energies are always positive.
