Nonene. Since it has c-c double bonds, we can be sure that its an alkene. To know its name, we can deduce from the number of carbon atoms ie 9.
solution:
You need to find the frequency, and they have already given you the wavelength. And since you already know the speed of light, you can use formula (2) to answer this problem. Remember to convert the nano meters to meters because the speed of light is in meters. 
Answer:
i think the forces are the same and size and in opposite directions
Explanation:
When a reactant is removed based on a reaction at equilibrium, the condition favors the backward reaction. This obeys the Le Chatelier's principle which states that any disturbance in the system shall be dealt in a way that the system counters that disturbance.
