Chemistry Carousel

• The number of protons is equal to the atomic number
• A base is a metal oxide, hydroxide or carbonate that will react with an acid.
• The negative electrode is the Cathode.
• The positive electrode is the Anode.
• Reduction with Carbon is the process of extracting metals which are less reactive than Carbon.
• An exothermic reaction is a reaction that releases energy to the surroundings.
• A substance with a pH of less than 7 is an Acid.
• Reduction is the gain of electrons.
• Oxidation is the loss of electrons
• A neutral solution has a pH of 7.
• oh- ions are present in an alkali.
• In an endothermic reaction, energy is transferred from the surroundings.
• The law of the conservation of energy states that energy cannot be created or destroyed, however it can be transferred from one store to another.
• A displacement reaction is where a more reactive element takes the place of a less reactive element.
• Electrolysis is the process in order to extract metals which are more reactive than Carbon.
• Reduction is the reaction where oxygen is removed from a compound.
• Oxidation is the loss of electrons.
• Gold is unreactive as it is found in the Earth's crust.
• The reactivity series is the list of elements ordered by reactivity.
• Ore is a material containing enough materials in it to be economically worthwhile to extract the metal.
