Answer:
The reaction begins and builds up heat. This heat causes the aluminum to melt and float on top of the liquid bromine (which is producing a cloud of vapor because the heat is also boiling it). Wherever the two elements meet, sparks, heat, and light are given off.
Explanation:
be more specific
I think it’s heat transfer but can’t guarantee
Answer:
Your answer should be B.) C, Si, Ge, Sn! I hope this helps you! :)
Before making a hypothesis, a scientist should make observations and conduct research.

Answer:
The products are 4-bromo-2-hexene and 2-bromo-3-hexene
Explanation:
The reaction starts between terminal carbon of of of the double bonds and 
. After attaching to the carbon, one double bond disapears leaveing nearby CH positively charged. This intermediate is a resonance hybrid of two possible structures. Reaction of bromide at one of the carbons gives the 1,2-addition product and at the other carbon gives 1,4-addition product.
