A construction worker attempts to pull a stake out of the ground by pulling on a rope that is attached to the stake and makes an angle of 60.0 degrees with the horizontal. Then worker exerts a force of 125 newtons on the rope. What is the magnitude of the upward component of t...

Consider the reaction N2 + 3H2 in equilibrium with 2 NH3 . At 25°C Ho = -92.22 kJ and So = -198.53 J/K. Using this information, calculate the equilibrium constant for the reaction at 226°C. (R = 8.314 J/K) Enter your answer using TWO significant figures. You may use sc...
