Is x + 2 a factor of f(x) = x^3 + 5x^2 + 8x + 4?

If so, factor completely.

1. Suppose a child used the word tunnel when driving through a tunnel and also when driving under an overpass, and finally, when hiding under a table. Is this overextension or underextension? What might account for this error? Think about the perceptual properties that these instances have in common.
2. Suppose another child used the word fish only for goldfish. Is this overextension or underextension? What might account for this? Think about what might be the prototype or core member of this category.

consider the following reaction at 25^oC

(CH3)3COH +HI ---> (CH3)3Cl + H20

The experimentally determined rate law for this reactionindicates that the reaction is first order in (CH3)3COH and thatthe reation is first order overall. Which of the following wouldproduce an increase in the rate of this reaction?

. a. decrease concentration of HI

b. increase concentratin of HI

c. increase concetration of (CH3)3COH

d. decrease the concentration of (CH3)Cl

e. it is impossible ot tell

2. which of these substances either appears or disappears thefastes?

4NH3 + 7O2 ----> 4NO2 +6H2O

3. Which of the follwoing is a key reason why chemists generallymeasure the INITIAL reaction rate?

a. one knows the concentration of reactants one puts in the testtubes

b one can ignore the rate of back-reactionfrom products toreactants when studying initial reaction rates as productconcetrations are zero

c. all of the above are reasons to measure the initial rate

d. none of the above are reasons to measure the initial rate

4. the rate law for a given reaction is rate =k[reactant]² , with k = 2.64x10⁴M^-1min^-1. If the initial concentration is0.250M, what is the initial rate, with correct units?

5. What will happen when the pressure increase by decreasing thevolume of the system in the reaction

3H₂ + N_{2 <---->} 2NH₃

A+B--> C rate= delta [C]/ delta t = k [A]^a[B]^b

a) Given the initial concentration of each of the reactants,calculate the final concentrations of A, B, and C. Assume thereaction goes to completion. [A]initial= 5.0 x 10^-7 M [B]initial=7.0 x 10^-4M [C]initial= 0

b) Which reagent is in large excess? Is it reasonable to say thatthe concentration of this reagent is a constant?

c) How might you rewrite the rate law to show that the rate of thereaction, run under the conditions given in question 2a, dependsupon the concentration of only one reactant?

d) The rate of the above reaction (using the initial reagentconcentrations given above) was studied monitoring theconcentration change of reactant A. A summary of the data obtainedfrom that study is given below. Based on these experiemntalresults, what is the order of the reaction with respect to thisreactant? Given this new info, rewrite the rate law derived inquestion 2c.

graph one: [reactant] vs. time is a graph of a downward slopingcurve, approaches zero as time goes on.

graph two: ln[reactant] vs. time is a graph of a less dramaticdownward sloping curve, approaches zero as time goes by

graph three: 1/[reactant] vs. time is a graph of a straight linewith a positive slope.

Suppose a weather forecast reports that the probability of snow this week is 0.18. The forecast states that if it snows this week, the probability that it snows next week is 0.29. If it does not snow this week, the probability that it snows next week is 0.12. The tree diagram depicts the possible weather event outcomes with the associated probabilities.
