The motion of the water molecules increase as heat is added.
Explanation:
Hello!
In this case, in general terms, one can know that molecules and heat have a relationship by which one affects the other, more specifically, the heat affects how the molecules behave. In such a way, as the heat added to a system increases its internal energy, one can notice that energy speeds up the molecules because they acquire such energy and the motion starts being increased, it means, the molecules start moving or vibrating faster than before of that heat addition. This is due to the increase of the internal energy, which based on the first law of thermodynamics is related with the velocity of the molecules.
In the HBr reaction, we will have a <u>markovniknov reaction</u> due to the <u>carbocation formation</u>. The Br- then would be added in the <u>most substituted</u> carbon of the double bond.
In the HBr/peroxide reaction we have the opposite case: an <u>anti-markovnikov reaction</u>. Therefore the Br- would be added in the <u>least substitued</u> carbon of the double bond.
Protons and neutrons have approximately the same mass, about 1.67 × 10−24 grams, which scientists define as one atomic mass unit (amu) or one Dalton. Each electron has a negative charge (−1) equal to the positive charge of a proton (+1). Neutrons are uncharged particles found within the nucleus.
