The graph represents the reaction 3H2 + N2 32NH3 as it reaches equilibrium. Based on the graph, which two statements about this reaction
are true? THE ANSWERS ARE A AND B.
a. equilibrium is reached after point 3. b. at point 4, the concentrations of NH3,N2, and H2 remain constant. c. after point 3, the reaction stops. d. equilibrium is fir. st reached at point 4.

Which statement is best supported by the information in the chart? wave y is moving the fastest. wave x is moving the fastest. all of the waves are moving at the same speed. all of the waves have the same value of wavelengths per second.

The electronic structure or chlorine is 2.8.7 what is the electronic structure of fluorine?

Astudent throws a water balloon with speed v0 from a height h = 1.76 m at an angle θ = 21° above the horizontal toward a target on the ground. the target is located a horizontal distance d = 9.5 m from the student’s feet. assume that the balloon moves without air resistance. use a cartesian coordinate system with the origin at the balloon's initial position. (a) what is the position vector, rtarge t, that originates from the balloon's original position and terminates at the target? put this in terms of h and d, and represent it as a vector using i and j. (b) in terms of the variables in the problem, determine the time, t, after the launch it takes the balloon to reach the target. your answer should not include h. (c) create an expression for the balloon's vertical position as a function of time, y(t), in terms of t, vo, g, and θ. (d) determine the magnitude of the balloon's initial velocity, v0, in meters per second, by eliminating t from the previous two expressions.
