Amolecule of antifreeze, ethylene glycol, has the formula c2h4(oh)2. how many atoms are there in one molecule of antifreeze?

the total atoms in one molecule of antifreeze = 2 + 6 + 2 = 10

Explanation:

The number of atoms in the given ethylene glycol molecule can be calculated from its molecular formula.

The molecular formula is :

The subscripts represent the multiplicity of the atoms present

Here the subscript on carbon = 2 so there are two carbon atoms

the subscript on hydrogen = 4 and two on OH, so the total hydrogen atoms = 6

The subscript on oxygen =2 so the total oxygen atoms= 2

Hence the total atoms in one molecule of antifreeze = 2 + 6 + 2 = 10

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
