Which of the following best describes the concept of leadership?

Sodium Chloride bag.jpg  [BLANK-1] The patient has an IV of 1,000 mL 0.45% sodium chloride infusing at 200 mL/hour. What number on the right side of the IV bag (through 9) indicates that 600 mL remains in the bag and 400 mL has infused into the patient.  [BLANK-2] Approximately how many hours do you have left to infuse for this bag? Use only numerals – DO NOT use labels!

Your new manager requires that he/she be at the center of all communication. He/she better hear things first and does not want the communication circulated among the team with out their knowledge. He/she also  determines and sets goals for the team, and is quick to praise and criticize. Their behaviors most closely align with which style?

Consider the following reaction and its equilibrium constant: SO2(g) + NO2(g) ⇌ SO3(g) + NO(g) Kc = 0.33 A reaction mixture contains 0.41 M SO 2, 0.14 M NO 2, 0.12 M SO 3 and 0.14 M NO. Calculate Q and determine which of the following statements is TRUE concerning this system?

Consider the following reaction at equilibrium. What effect will removing NO2 have on the system? SO2(g) + NO2(g) ⇌ SO3(g) + NO(g)

The equilibrium constant,  K p, equals 3.40 at 25°C for the isomerization reaction:   cis-2-butene ⇌  trans-2-butene.  (coefficients are one for both the reactant and the product)If a flask initially contains 2.00 atm of each gas, calculate Q and determine in what direction will the system shift to reach equilibrium?

Given the following rate law, how does the rate of reaction change if the concentration of Y is doubled? Rate = k [X]2[Y]3

What is an indication that you have a growth mindset? 

Use the standard half-cell potentials listed below to calculate the standard cell potential for the following reaction occurring in an electrochemical cell at 25°C.  Cu(s) + Mg2+(aq) → Mg(s) + Cu2+(aq)Mg2+(aq) + 2 e⁻ → Mg(s) E° = -2.38 V Cu2+(aq) + 2 e⁻ → Cu(s) E° = +0.34 V
