Answer the following questions about two possible reaction mechanisms for the same reaction. Determine the overall balanced equation.
What is the role of E2X2 in the reaction mechanism? Explain your reasoning.
Explain why Reaction Mechanism 1 is less likely to occur in terms of the collision theory.
For Reaction Mechanism 2, determine the rate law of the reaction based on the rate determining step of the reaction mechanism.

The image shows a process that releases nuclear energy which statement best identifies the process shown the process must be fusion because energy is released the process must be fusion because of have your nucleus formed a smaller nuclei the process must be fission because a large nucleus breaks into smaller nuclei the process must be fission because neutrons are formed

Nebulae are enormous clouds in outer space. they are made mostly of hydrogen gas, helium gas, and dust. some nebulae glow brightly, while others do not. the stars that people see are huge, bright balls of glowing gas. they are made mostly of hydrogen and helium. which statement correctly describes other ways in which nebulae and stars are different? a. stars can form inside a nebula but a nebula can never be produced by any star. b. a star always has a higher density than a nebula. c. stars can never form inside a nebula but a nebula can be produced by any star. d. a nebula always has a higher density than a star.

Connect the whole numbers on the periodic table to indicate what they represent?
