Select all the correct answers. which compounds have the empirical formula ch2o? a. c2h4o2 b. c3h6o3 c. ch2o2 d. c5h10o5 e. c6h12o6

Compounds having the same empirical formula are:

Explanation:

Empirical formula tells us about the proportion of the elements present in the compound but it do not tells us about the actual numbers of atoms of the elements present in the compound.

In given empirical formula that is proportion of  C:H:O = 1:2:1

In the proportion of C:H:O =2:4:2= 1:2:1

In the proportion of C:H:O =3:6:3= 1:2:1

In the proportion of C:H:O =1:2:2= 1:2:2

In the proportion of C:H:O =5:10:5= 1:2:1

In the proportion of C:H:O =6:12:6= 1:2:1

Compounds having the given empirical formula are:

The chemical compounds that have the empirical formula are:

A.C2H4O2

B.C3H6O3

D.C5H10O5

E.C6H12O6

An empirical formula can be defined as a formula that gives the smallest and simplest whole number ratio of the atoms of a chemical element found in a chemical compound.

The simplest whole number ratio of the atoms of   is:

= 1:2:1

For :

= 2:4:2 = 1:2:1

For :

= 3:6:3 = 1:2:1.

For :

= 1:2:2 = 1:1:1  (Incorrect)

For :

= 5:10:5 = 1:2:1

For :

= 6:12:6 = 1:2:1

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.
