Which of the following is a statement of hess's law? if a reaction is carried out in a series of steps, the δh for the reaction will equal the sum of the enthalpy changes for the individual steps. the δh of a reaction depends on the physical states of the reactants and products. the δh for a process in the forward direction is equal in magnitude and opposite in sign to the δh for the process in the reverse direction. the δh for a process in the forward direction is equal to the δh for the process in the reverse direction. if a reaction is carried out in a series of steps, the δh for the reaction will equal the product of the enthalpy changes for the individual steps.

C) The ΔH for a process in the forward direction is equal in magnitude and opposite in sign to ... E) The ΔH of a reaction depends on the physical states of the reactants and products.

Explanation:

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
