I and II onlyd. I and III onlye. I only

Consider the reaction and its rate law given below for the next four questions. 2 A(g) + B(g) → C(g)rate = k[A]2[B] At the beginning of one trial of this reaction[A] = 4.0 M and [B] = 1.0 M The rate of formation of C was 0.048 mole L−1 sec−1  ENTER THE LETTER CORRESPONDING TO YOUR SELECTION IN THE SPACE PROVIDED. The numerical value of k, the rate constant, for this reaction is closest to a. 3 × 10−3b. 1 × 10−2c. 8 × 10−1d. 4 × 100e. 3 × 102 Which is the label for k, the rate constant?a. L2 mol−1 sec−1b. L2 mol−2 sec−1c. L2 mol−2sec−2d. L mol−1 sec−1e. mol2 L−2 sec−1 16. When [B] decreases 0.4 M, what will be the value of [A]?a. 1.6 Mb. 3.6 Mc. 0.8 Md. 2.8 Me. 3.4 M 17. Which of the following describes how the rate for this trial reaction, at constant temperature, changes as [B]approaches 0.4 mol L−1? a. The rate remains the same because the rate constant remains the same.b. The rate remains the same because the temperature remains the same.c. The rate decreases because the concentration of the reactants decreases.d. The rate decreases because the concentration of the products increases.e. The rate remains the same because the energy of activation remains the same.

The nurse manager knows that the most serious effect that absenteeism has on the nursing unit is that:

The charge nurse is concerned about the service provided on the unit. Which of the following patient satisfaction survey results might provide useful information for the nurse?

Read the sentence carefully. If the sentence does not have any grammar errors, write CORRECT in the text entry box. Do not leave a blank textbox and do not just copy the sentence. If the sentence is incorrect, there will be two errors. Rewrite the sentence and correct the two errors in the text entry box. Highlight your corrections. SENTENCE: Is Vanessa and her sister going to the university after they receive their high school diploma?

An example of a factor that would impede a patient’s learning is:

With revenue reductions and cost saving measures, the number of managers has been reduced, which has increased the number of team leaders supervised by managers by as many as three. This change may result in:
