another of the same molecule. Polarity simply means that the molecule has both a negatively and positively charged end. The polarity of water is important because it is responsible for dissolving other polar molecules like ionic compounds (such as salt) and sugars. To form ions‚ ionic compounds must be dissolved in water. This is important because for most biological reactions to occur‚ the reactants must be dissolved in water. Substances that cannot be dissolved by water (such as oils) are called fat

Terms Richard was observing black swallowtail butterflies in the field. Which one of these is an observation he made about a black swallowtail butterfly? The most valid and reliable test of the hypothesis‚ more pine seeds germinate after a forest fire‚ would include an experimental group of pine seeds that was recovered from a fire area and pine seeds that were — A student wanted to look at plant growth in five different soil samples. He planted the same type of seeds in identical containers and

15.2 Born-Haber Cycle Our calculations of enthalpies so far have involved covalent substances. Now we need to look at the enthalpy changes involved in the formation of giant ionic lattices. Lattice enthalpy is defined as either the: ’the enthalpy change that occurs when one mole of a solid ionic crystal is broken into its ions in the gaseous state‚ at standard temperature and pressure. Because all the bonds in the ionic lattice are broken‚ it is an endothermic process‚ ∆H is positive. ’ The
