Synthesis Reaction

General Formulas and Concepts:

<u>Chemistry - Reactions</u>

  • Synthesis Reactions: A + B → AB
  • Decomposition Reactions: AB → A + B
  • Single-Replacement Reactions: A + BC → AB + C
  • Double-Replacement Reactions: AB + CD → AD + BC

Explanation:

<u>Step 1: Define</u>

RxN:   2Na + I₂ → 2NaI

<u>Step 2: Identify</u>

2Na + I₂ → 2NaI

A + B → AB

  • A = Na
  • B = I₂
  • C = NaI

What happens when a solid is dissolved into a liquid?
daser333 [38]

When a solid dissolves in a liquid to form a solution, solid particles become evenly dispersed among liquid particles.

<h3>What are solutions?</h3>

Solutions are formed when a solute particle dissolves in another substance known as a solvent.

Usually, solutions are formed when solids dissolve in liquids.

The solid is the solute while the liquid is the solvent.

When a solid dissolves in a liquid, solid particles become evenly dispersed among liquid particles.

Therefore, solutions are formed when solute particles dissolve in solvents.
