Answer the following question given this paragraph: Again, the transfer of an H + ion leaves the oxidation numbers unaffected. In summary, redox reactions can always be recognized by a change in oxidation number of two of the atoms in the reaction. Any reaction in which no oxidation numbers change is not a redox reaction. Q: Redox reactions can always be recognized by a change in what number of two of the atoms in the reaction? Choices: - fermentation - oxygen - precipitation - oxidation A:
(Answer)
oxidation
Ques: Answer the following question given this paragraph: Two chemical species combine to produce a new compound. The general expression for this reaction is A + B C. Q: What are the largest phylum of the animal kingdom? Choices: - Crustacea - Chelicerata - Pycnogonida - arthropods A:
Ans: arthropods
(Q).
Answer the following question given this paragraph: 12.4 Viscosity and Laminar Flow; Poiseuille's Law Laminar flow is characterized by smooth flow of the fluid in layers that do not mix. Turbulence is characterized by eddies and swirls that mix layers of fluid together. Fluid viscosity is due to friction within a fluid. Representative values are given in Table 12.1. Viscosity has units of. Q: What property is characterized by eddies and swirls that mix layers of fluid together, unlike laminar flow? Choices: - combustion - compression - evaporation - turbulence A:
(A).
turbulence
Ques:Answer the following question given this paragraph: To express the uncertainty in a measurement, we can calculate percent uncertainty . Percent uncertainty is the ratio of the uncertainty to the measured value, multiplied by one-hundred. For instance, the percent uncertainty associated with the measurement of (52.9 0.5 mL), would be. Q: What is the ratio of the uncertainty to the measured value, multiplied by one-hundred called? Choices: - variable uncertainty - amount uncertainty - percent inconsistency - percent uncertainty A:

Ans:percent uncertainty
Question: Answer the following question given this paragraph: A combination reaction makes a new substance from more than one reactant; a redox reaction rearranges electrons. Not all combination reactions are redox reactions, and not all redox reactions are combination reactions. Q: A redox reaction rearranges what subatomic particles? Choices: - neutrons - water molecules - protons - electrons A:
Answer:
electrons
