Calculate the frequency separation (in megahertz) of the nuclear spin levels of a \({ }^{13} \mathrm{C}\) nucleus in a magnetic field of 15.4T given that its magnetogyric ratio is \(6.73 \times 10^{-7} \mathrm{~T}^{-1} \mathrm{~s}^{-1}\).

Chemistry 200 – Week 7 10/3/2017 Observable Properties of Water: Essential questions: o What are observable properties of water o How can chemistry explain properties of water What do we mean by “water” o Multiple forms and states of water – ice, steam, ocean water, etc. Water molecule o Chemical symbol – H2O o Atomic symbol – atoms that make up the molecules o Subscript (below) – how many atoms of each type Water is one of a few substances that we can observe all three states of matter o Gas, solid, liquid o Condensation – gas to liquid o Vaporization – liquid to gas o Freezing – liquid to solid o Sublimation – solid to gas Examples of water phase change: o Condensation – cold coke cans, dew in the morning, bathroom mirror o Evaporation – eater puddle disappears during the day, dew on plant leaves disappear during the day o Sublimation – snow pile gradually gets smaller o Deposition – frost Evaporation and condensation occur all the time around us Sublimation of dry ice – dry ice is the solid form of carbon dioxide Temperatures and water state change o Boiling point: the temperature in which liquid water boils and turns into gas o Melting/freezing point: the temperature in which water changes its state between a solid and a liquid Chemistry 200 – Week 7 10/3/2017 Observable Properties of Water: Essent
