6. A block lies on a smooth inclined plane tilted at an angle of 35° to the horizontal a) Draw the free body diagram for the block b) Determine the block's acceleration as its slide down the inclined plane c) If the block started from rest 8.5 m up the incline from its base, determine the block's speed when it reaches the bottom of the incline d) How long did it take the block to reach the bottom of the inclined plane?

Using this reversible reaction, answer the questions below: n2o4 2no2 (colorless) (reddish-brown) -as the temperature increased, what happened to the n2o4 concentration? -was the formation of reactants or products favored by the addition of heat? -which reaction is exothermic? right to left or left to right? -if the change of enthalpy of this reaction when proceeding left to right is 14 kcal, which chemical equation is correct? n2o4 2no2 + 14 kcal n2o4 2no2, hr = +14 kcal n2o4 + 14 kcal 2no2 n2o4 2no2, hr = -14 kcal
