Wiley Plus Exam 1 Questions With 100% Correct Answers 2024 One ml of the 0.1 M supstance -A is added to 9 mls of water, and 1ml of the dilution is added to another 9 ml of water. What is the concentration of the final dilution in molar (M), millimolar (mM), micromolar (uM), and nanomolar (nM)? - answer✔✔.001 M, 1 mM, 1000 uM, 10^6 nM How many moles of sodium hydroxide (NaOH ) are in 10 g of NaOH? - answer✔✔.25 mol How ma ny grams of solid calcium hydroxide Ca(OH)2 are required to prepare 200 mL of a 0.05 M solution? Molar mass (formula weight) of Ca = 40.1 g/mol, O = 16.0 g/mol, and H = 1.01 g/mol. - answer✔✔.741 g T/F: some eukaryotes, such as yeast, are unicellular - answer✔✔F T/F: cells typically contain thousands of different types of molecules - answer✔✔T T/F: The three domains are the archaea (also known as archaebacteria), the bacteria, (sometimes called eubacteria) and the eukaryotes (eukarya). Classification of o rganisms by analysis of their genetic material (for e.g., the classification by RNA analysis performed by Carl Woese) led to the grouping of all organisms into three domains, the archaea (also known as archaebacteria), the prokaryotes (prokarya), and the e ukaryotes (eukarya). - answer✔✔T T/F: with respect to energy, life obeys the laws of thermodynamics - answer✔✔T T/F: Water is considered polar because the oxygen atom carries a partial negative charge of -
0.66e, while the hydrogen atoms are each partially positive, +0.33e. Water is considered a polar molecule because the oxygen atom is much larger than the hydrogens. - answer✔✔F How do weak acids ionize - answer✔✔only partially T/F: The buffering capacity of a weak acid is greatest when pH = pKa. - answer✔✔T Which of the major types of biomolecules is never found in a polymeric form? amino acids carbohydrates nucleotides lipids none of the above - answer✔✔lipids An exergonic process _____. occurs without the addition of free energy has a ΔG< 0 is spontaneous will have more products than reactants at equilibrium all of the above - answer✔✔all of the above If the following two reactions were coupled, what would be the ΔG for the overall exergonic reaction? ATP + H2O --> ADP + Pi , ΔG = -31 kJ/mol Glucose + Pi --> glucose -1-phosphate + H2O, ΔG = 21 kJ/mol - answer✔✔-10 kJ/mol 3 domains of life - answer✔✔bacteria, archaea, eukarya Which of the following is a physical property of water that results from hydrogen bonding? high boiling point relative to molecular weight
