Low levels of AFP are associated with:

Variable decelerations are generally caused by:

Aneuploidy screening should be offered to:

 Initially 3 moles of A and 4 moles of B are placed in a 0.75 L flask.  At equilibrium, there is 0.4 moles of C.  Find the value of Keq. A(g) + B(g)   3C(g) + 2D(g) You may use the desmos online calculator    

  a)         Explain Le Châtelier’s Principle.                                                     b)         Given the reaction:               2SO2(g) + O2(g) ↔ 2SO3(g) + 250J   What would happen if i) the temperature were to increase? ii) the pressure were to increase?           

a) Explain what makes a molecule organic.  How could you distinguish between an organic and inorganic molecule? b) How would you identify the #1 carbon when naming an organic molecule?

Use Hess’ Law to find the change in enthalpy for the following reactions. a) H2O(g)  + Mg(s) –> MgO(s) + H2(g)   b) 2MgO(s) + NO2(g) + 3/2H2(g) –> 2Mg(s) + 2O2(g) + NH3(g)

a) Using examples, compare transverse and longitudinal waves. b) What is the difference between a waves frequency and it’s period?

a) if an object has an initial velocity of 2.6 m/s [East] and accelerates at 1.5 m/s2 [West] for 8 seconds, solve for it’s final velocity and displacement b) if an object is dropped from a window that is 72m above the ground, how long will it take to reach the ground and how fast will it be moving the instant before it hit the ground?
