Chemical Reactions

By Matt Reeder


What is a chemical reaction
What is a chemical reaction?

A chemical reaction is a reaction between two atoms forming a chemical bond resulting in a chemical compound.



What is a chemical equation
What is a chemical equation?

A chemical equation is a way of writing out and describing a chemical reaction.


Why are chemical equations used
Why are chemical equations used?

Chemical equations are used to simplify and express the specific reactants and product of a chemical reaction.


Should chemical equations be balanced
Should chemical equations be balanced?

YES! The law of conservation of matter states that matter cannot be created or destroyed.

All elements that are a part of the left side of the equation must appear, in some form, on the left side of the equation.

Synthesis reaction
SYNTHESIS REACTION

  • A type of reaction where two or more atoms join to form a more complex compound.

  • Reactant + reactant product

  • 2H2+02H2O



Decomposition reaction
DECOMPOSITION REACTION

  • Opposite of a Synthesis reaction.

  • One reactant compound separates resulting in two or more products.

  • Reactant Product + Product

  • 2H2O2 2H2 + O2



Single replacement reaction
SINGLE REPLACEMENT REACTION

  • A reaction involving more than two elements in which one element takes the place of another one.

  • Reactant + reactant product + product

  • Zn + 2HCl ZnCl2 + H2



Double displacement
Double Displacement

  • Two compounds react to form two new compounds.

  • reactant + reactant Product + product

  • AgNO3 + NaClAgCl + NaNO3
