When a particular alkene is treated with ozone and then dimethyl sulfide, 2 compounds with the structural formulas CH3CH2COCH3 and CH3CH2CHO are formed. What was the alkene starting material? A) 2-methyl-2-hexene
B) 3-heptene
C) 4-methyl-4-hexene
D) 3-methyl-3-hexene
E) 1-heptene

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.

idk what is it? is this a question that you know the answer or u dont

here are some of the ways in which chemical and nuclear reactions differ.
