Statement Coverage - measures whether each executable statement is encountered. Decision Coverage - measures whether Boolean expressions tested in control structures (such as if-statements or while-statements) are evaluated to both true and false Condition Coverage - measures the true or false outcome of each Boolean subexpression Multiple Condition Coverage - measures whether every possible combination of Boolean subexpression occurs Path Coverage - measures whether each of the possible p...

EDF 6223 Exam 1 Questions and Answers Already Passed _____________ occurs when the equation if A = B and if B = C, then A = C. In other words one stimulus is matched to a second stimulus. The second stimulus is matched to the third stimulus. By this relationship, the subject learns that the first stimulus and third stimulus are also matching. For example, if you say "bird" and show a child a picture of a bird, then you show a picture of a bird and match it to a real bird in a cage, the...

Thin layer chromatography can use silica plates which are very polar. Will polar or non polar substances have lower Rf values on this plate? ANS -Polar substances - they will have a higher affinity for the silica and thus will not travel as far as the non polar substances A titration of a strong acid with a strong base or vice versa has an equivalence point around what pH? ANS -7 What type of bond is usually disrupted during denaturation of proteins? ANS -H bond Is uracil a purine or...

CHEM 129 EXAM 3 Questions With 100% Correct Answers Acids and bases are usually demoted as strong or weak, what's the difference? - answer- Strong acids and bases - reaction with water is approximately 100% - Weak acids and bases - reaction with water is much less than 100% What does acid and base strength not dictate? - answerAcid or base strength is not a measure of concentration What are some examples of strong acids? - answerHNO3, HCl, H2SO4 and HClO4 are strong acids What are ele...

TBR Chemistry Ch. 5 Exam Questions & Answers 2024 Buffer - ANSWER-a solution where pH remains relatively constant after the addition of either strong acid or strong base. Can be made by combining a conjugate pair in roughly equal mole portions (must be weak acid/base pair). The addition of strong base or strong acid shifts teh ratio of weak acid (HA) to its conjugate base (A⁻), but the pH does not change, if the A⁻:HA ratio is close to 1.0 Can also be made by partially titrating a...

CHEM-C125 EXAM #3 QUESTIONS WITH CORRECT ANSWERS ten-fold difference in concentration of conjugate pairs - Answer- any pH change of 1 unit is a ... the choice of the system and thus the Ka. the ratio of the concentration of conjugate pairs. - Answer- what does the pH of a buffer depend upon? added strong acid or added strong base - Answer- buffering capacity: has the ability to absorb... need to prepare a buffer solution with a specific pH; assume [base] = [acid] - Answer- how to ch...
