Double bonds can act as Lewis bases, sharing their electrons with Lewis acids. A. Use curved arrows to show how the alkene below will react with HCl.
B. Make the ends of your arrows specify the origin and destination of reorganizing electrons.
C. Draw the resulting carbocation.

See explanation and image attached

Explanation:

The reaction between an alkene and a hydrogen halide is an addition reaction. The ends of the arrow in the image attached shows the movement of electrons during the reaction of the alkene shown with HCl.

The carbocation intermediate formed in the reaction is also shown. Since the alkene is symmetrically substituted, only one product is obtained.

the molecules move in straight line until they collide with each other or with the walls of the container. collisions are perfectly elastic; when two molecules collide, they change their directions and kinetic energies, but the total kinetic energy is conserved.

explanation:

2fe + 3h2so4 -> fe2(so4)3 + 3h2

it is necessary to balance equations in order to get the proper amount of reactants as well as products in order not to make a miscalculation.

you cannot change the subscripts as that would change the substance itself. for instance, diatomic elements such as h2 only have the subscript two when a gas. another example would be so4, if you were to change the subscript, the element would no longer be sulfate.

we change the coefficients instead as that only changes the number of molecules rather than the substance itself.

hope this !
