Testbank, Question What is the IUPAC name for the following compound 1-ethyl-2-isopropyl-1-methyloxirane 1-ethyl-2,4-dimethyloxyhexane 2-ethyl-3-isopropyl-2-methyloxirane 3-ethyl-2-isopropyl-3-methyloxirane 2,4-dimethyloxyhexane

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z

answer

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.
