Redox

• Which gains election oxidation or reduction

  Reduction
• What is activation energy

  The minimum energy needed by particles when they collide for a reaction to occur
• When an element gains oxygen, the word used to describe it is Oxidation
• When an element loses oxygen, the word used to describe it is Reduction
• When a metal reacts with an acid, the two things produced are salt and hydrogen gas
• A redox reaction involves both Reduction and Oxidation happening at the same time
• The word used to describe when an element loses electrons is Oxidation
• The symbol for an electron is e-
• Two factors that must balance each side of a half equation are:

  • The number of atoms of each element
  • The total charge
• An everyday example of an exothermic reaction is a self-heating
• Endothermic reactions absorb heat from the surroundings, causing a decrease in temperature
• When an acid is neutralized by an alkali, the temperature would increase
• The independent variable is the factor that is deliberately changed in an experiment
• Resolution means the smallest change in quantity being measured
• Apparatus means equipment used in an experiment
• Activation energy is the minimum energy needed by particles to react
• Bond energy is the amount of energy needed to break one mole of a specific type of bond
