Answer:
Anything that takes up space and has mass
"released from" the atoms
From the calculations, the heat of the reaction is 44.4 kJ/mol.
<h3>What is the enthalpy of reaction?</h3>
The enthalpy of reaction refers to the amount of heat that is absorbed or evolved in a reaction.
Number of moles of NaOH = 1.1 g /40 g/mol = 0.0275 moles
Mass of the water = 22.1 mL or 22.1 g
Given that;
H= mcdT
H = 22.1 g *4.184 * (31.4 - 18.2)
H = 1221 J or 1.221kJ
ΔH rxn = -(1.221kJ)/0.0275 moles
ΔH rxn = 44.4 kJ/mol

Answer:
The question has some part missing which I have added in the attachment.
Explanation:
The reactions given occur under certain reagents, which we are told to pick for each of the reaction synthesis. Conventionally, halogens have the ability to undergo addition reactions with hydrocarbons by breaking down the double or triple bond in them to a single bond, this usually occur by electron donation and electron acceptor.
The attachment shows the reactions and the necessary reagents required for each
