Chapter 5, Problem 42E
The opening quote of this chapter states that “Man masters nature not by force but by understanding. That is why science has succeeded where magic failed: because it has looked for no spell to cast." What do you think Bronowski meant by this? How does this apply to

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.
Consider the structures of greenhouse gases, CO2 and CH4. Carbon dioxide has a very long lifetime in the air (centuries) versus methane that has a relatively short lifetime (decade). The lifetime of a molecule is also a reflection of the bonding and stability of the molecule. Discuss why you think these greenhouse gases have such different lifetimes in the atmosphere based on molecular structure, bond types, etc...

- Carbon monoxide (CO) contains C-O bonds. Which if the following statements are true about the bonding electrons in this molecule? a.) The bonding electrons will spend more time around the C atom as it needs an octet of electrons more than the O atom b.) The bonding electrons will spend more time around the O atom as it attracts the electrons more strongly c.) The bonding electrons will be shared equally between C and O atoms d.) The bonding electrons will spend more time around the C atom as it attracts the electrons more stronglyarrow_forwardCarbon naturally occurs in two forms: diamond and graphite. Why do these two forms have very different properties? The key difference is that diamonds have other elements bonded within their structure. The differences are explained by the number of covalent and ionic bonds within each substance. The differences are explained by the density: graphite is very high and diamond is much lower. The differences are explained by how the carbon atoms within each substance are covalently bonded together.arrow_forwardWe have just finished studying different types of bonding in matter and their properties.
