Chemistry- 7 - Representing & Balancing Chemical Reactions ( States) 

 The arrow (→) in a chemical reaction means “produces” or “forms”.

A chemical reaction is a process by which one or more substances (the reactants) are converted to one or more new chemicals (the products).

States:

  • Aqueous is a directive state of solid that focuses on highlighting the state where it is dissolved in some sort of liquid and the particles move apart like transitioning (melting)
  • Whenever we have a synthesis with Oxcegent as the anion then a acid accors
  • Oxidation: A metal or a non-metal combines with oxygen, producing an oxide
    • Very common
    • Reactions are always exothermic

Types of equations :

 The (light) written over the line represents a directive that speeds up the process

 Basically symbol equations

*Diatomic Elements have to have a 2 with them because they are bonded together

  • Like having an Octect of 2

Law of Conservation of Mass \n

Matter is neither created nor destroyed in chemical reactions

  • If we account for ALL reactants and ALL products, the total mass will be the same at any point in a closed system
  • This has profound implications for how we represent chemical equations…
