Water has unusually strong hydrogen bonding. These bonds require extra energy to break. Therefore, water has a high specific heat.

- Water’s Polarity. One of water’s important properties is that it is composed of polar molecules: the hydrogen and oxygen within water molecules (H2O) form polar covalent bonds.
- Water’s States: Gas, Liquid, and Solid. The formation of hydrogen bonds is an important quality of the liquid water that is crucial to life as we know it.
- Water’s High Heat Capacity. Water’s high heat capacity is a property that hydrogen bonding among water molecules causes. Water has the highest specific heat capacity of any liquid.
- Water’s Heat of Vaporization. Water also has a high heat of vaporization, the amount of energy required to change one gram of a liquid substance to a gas.
There are several differences. To start, DNA stands for deoxyribonucleic acid, while RNA stands for ribonucleic acid. These names describe the sugar that makes up their backbone--DNA = deoxyribose and RNA = ribose. Second, while each has four nucleiotide bases, there is one difference.

- You gain familiarity through repetition. Practice is key.
- From a chemistry perspective, saturated fats have no double bonds between carbon atoms, while unsaturated fats have one or more double bonds. From...
As with acids, bases can either be strong or weak, depending on their extent of ionization. A strong base is a base, which ionizes completely in an aqueous solution. The most common strong bases are soluble metal hydroxide compounds such as potassium hydroxide.
The building blocks of DNA are nucleotides, which are made up of three parts: a deoxyribose (5-carbon sugar), a phosphate group, and a nitrogenous base ( Figure 9.3 ). There are four types of nitrogenous bases in DNA. Adenine (A) and guanine (G) are double-ringed purines, and cytosine (C) and thymine (T) are smaller, single-ringed pyrimidines.
