When a gas atom (or molecule) is ionized, in which direction are the electrons accelerated? - ANSWERSToward the cylinder Being negatively-charged, electrons would be accelerated toward the cylinder, since the cylinder is at a higher potential than the wire. [Note that the cylinder is connected to the (+) terminal of the battery, while the wire is connected to the (-) terminal.] Which of the following changes would decrease the sensitivity of the Geiger counter? - ANSWERSUsing a gas with ...

(Chemistry) Consider the reaction rate described by the following equation. Rate = k[A]^m*[B]^n The overall reaction is said to be SECOND ORDER when: A. k is constant, m=0, and n=0 B. k is constant, m=1, and n=1 C. k is constant, m=2, and n=2 D. k=2, and m and n are variable - ANSWERSB. k is constant, m=1, and n=1 *The reaction is second order if the sum of the exponents "m" and "n" equals 2. In rate laws, k is the rate constant. The sum of the exponents equals 2 ...

Which of the following best explains why the protocol requires the student to add the tea leaves to 80 °C H2O in Step 1? (A) H2O at 80 °C to dampen the dry tea leaves. (B) Caffeine is relatively soluble in H2O at 80 °C. (C) H2O at 80 °C serves as a solvent for the reaction of calcium carbonate and caffeine. (D) H2O at 80 °C is below the boiling point. - ANSWERS(B) Consider the various answer choices. Answer choice A does not make sense since liquid water is sufficient to dampen the leav...
