The double-replacement reaction of sulfuric acid with aluminum hydroxide produces aluminum sulfate salt and water. balance this skeleton equation, then determine the mole ratio of h2so4: h2o. h2so4 + al(oh)3 al2(so4)3 + h2o? (how do i determine the mole ration? )
a) 1: 1
b) 2: 3
c) 3: 1
d) 3: 6
e) 6: 3

D) 3:6

Explanation:

This is a double displacement reaction in which exchange of ions take place.

According to the law of conservation of mass, mass is neither created nor destroyed. Thus the mass of products must be equal to the mass of reactants.The number of atoms of each element must be same on both sides of the reaction.Thus the equation is balanced.

The balanced chemical equation is:

The mole ratio of is 3:6.

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.
