Microbiology: An Introduction, 13th Edition Chapter 2 (100% accurate answers)

Consider an atom of sodium with an atomic number of 11 and an atomic weight of 23. How many neutrons are in this atom? correct answers 21 Small organic molecules are joined to form macromolecules through correct answers condensation reactions When an atom's outer electron shell is only partially filled, the atom is considered correct answers chemically unstable The valence of oxygen is 2. This means that oxygen correct answers will form up to two bonds A negatively or positively charged atom is called a/an correct answers ion Hydrogen bonds are important in the formation of correct answers interactions between complex molecules such as proteins Consider the following reaction. A + B → AB What kind of chemical reaction does this illustrate? correct answers synthesis reaction CH4 is an example of an correct answers organic molecule Which characteristic of water accounts for its excellent solvent properties? correct answers Water has a negatively charged portion and a positively charged portion. Which quality of water accounts for its characteristic role as a reactant or product in many chemical reactions? correct answers Water can split into a hydrogen ion and a hydroxide ion. A base can be defined as a correct answers proton acceptor A solution with a pH of 5 is correct answers acidic The pH of a solution reflects the hydrogen ion concentration. A change from pH 7 to pH 8 reflects a __________ change in hydrogen ion concentration. correct answers 10-fold Different functional groups confer different properties on organic molecules. For example, the hydroxyl group of alcohol is hydrophilic and thus correct answers attracts water to it The relationship between a nucleotide and a nucleic acid is similar to the relationship between an amino acid and a correct answers protein ribonucleic acid correct answers steroid
