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.


Why do chemical reactions happen

Why do chemical reactions happen?


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.

The arrow in a chemical equation

The arrow in a chemical equation

The arrow in a chemical equation represents the action, or reaction taking place forming the chemical bond.

2H2 + O2 H2O


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


Peanut butter chocolate reeses

Peanut butter + Chocolate Reeses


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


Firecracker explosion cardboard

Firecracker = Explosion + cardboard


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


Baby and toy big brother baby big brother and toy

Baby and toy + big brother = baby + big brother and toy


Double displacement

Double Displacement

  • Two compounds react to form two new compounds.

  • reactant + reactant Product + product

  • AgNO3 + NaClAgCl + NaNO3
