In what kind of reaction do two or more substances combine to form a new compound

Chemistry
1 answer:
Misha Larkins [42]3 years ago
4 0

Answer:

Combination or synthesis

Explanation:

In combination or synthesis, there is formation of a single product from two or more reactants e.g:

               H₂ + I₂ → 2HI

Here a compound forms from the association of the consituent elements.

Other kinds of chemical reactions we have are:

  1. Decomposition or cracking
  2. Single replacement or single displacement
  3. Double replacement or double decomposition or metathesis.

The diagram shows the potential energy changes for a reaction pathway.
Nitella [24]

1) To find the change in enthalpy, determine the difference between the potential energy of the products and the potential energy of the reactants. (on this diagram, C-A) To find the activation energy, find the difference between the potential energy of the reactants and the "peak" of the curve (on this diagram, B-A). For this diagram, both the enthalpy and activation energy are positive.

2) If the reaction was exothermic, enthalpy would be negative, and the potential energy of the reactants would be greater than the potential energy of the products.
