Which term is not correctly matched?

When two similar liquids mix to form a solution, the entropy of solution (ΔSsoln) is expected to be

An educator wants to construct a 95% confidence interval for the proportion of elementary school children in Colorado who are proficient in reading. The results of a recent statewide test suggested that the proportion is 0.70. Using this estimate, what sample size is needed to have a confidence interval to within 5 percentage points? Hints: Prior estimate is given; n =

At a given temperature and pressure, which of the following would be expected to have the greatest molar entropy? A) Br2(s) B) Br2(l) C) Br2(g) D) All of these would be expected to have the same molar entropy.

Which of the following does not affect the solubility of a solute in a given solvent?

Use the given average bond dissociation energies, D, to estimate ΔH for the following reaction:      CH3Br(g) + H2(g) →CH4(g) + HBr(g) Bond        D, kJ/mol C-Br 270 H-Br 366 H-H 436 C-H 410

A 51.6-mL dilute solution of acid at 23.85°C is mixed with 48.5 mL of a dilute solution of base, also at 23.85°C, in a coffee-cup calorimeter. After the  reaction occurs, the temperature of the resulting mixture is 27.25°C. The density of the final solution is 1.03 g/mL. Calculate the amount of heat evolved. Assume the specific heat of the solution is 4.184 J/g•°C. The heat capacity of the calorimeter is 23.9 J/°C.

Which of the following statement is not correct about DNA replication?

Is most of our DNA made up of genes?

Out of the following options, select the two conditions that are most likely to produce oscillations in population size.
