Chemistry - Bromination. Bromination: Any reaction or process in which bromine (and no other elements) are introduced into a molecule. Bromination of an alkene by electrophilic addition of Br2.
How does bromination of alkenes work?
Alkenes react in the cold with pure liquid bromine, or with a solution of bromine in an organic solvent like tetrachloromethane. The double bond breaks, and a bromine atom becomes attached to each carbon. The bromine loses its original red-brown color to give a colorless liquid.
To solve this problem we will apply the concepts related to the conversion of units for which we will have that 1 slug is equal to 14.59kg. At the same time we will use Newton's second law for which weight is defined as the product between mass and acceleration (Due to gravity). This is then
A: Using the conversion ratio of slug to kilogram we have to,

Then


B: Using Newton's second law we have to,



Answer:
Yes, the heat that flows into the system is used to change the internal energy of the gas and becomes work done by the piston.
Explanation:
First law of thermodynamics known as Law of Conservation of Energy, states that energy can neither be created nor destroyed; energy can only be transferred or changed from one form to another.
The first law of thermodynamics states that the change in internal energy of a system equals the net heat transfer into the system minus the net work done by the system. In equation form, the first law of thermodynamics.
This is the first law of thermodynamics
ΔE= Q− W
ΔE= change internal energy of the system.
Q= heat transfer into the system
And
W= work done by the system.
Rewriting the equation
ΔE= Q− W
Q=ΔE +W
Show that the heat flowing l into the system is transferred to the internal energy of the system and the work done by the piston
So the third option is correct
