Chemical Change Flashcards
Physical Properties:
Properties that can be observed using the five senses or that you can measure.
Chemical Properties:
Properties that combine together to create another thing/more.
flammability:
an indicator of how easily a substance catches fire
reactivity:
a measure of how likely a particular metal is to take part in a displacement reaction
toxicity:
the danger to your health caused when poisonous substances combine with chemicals in your body to produce new substances and damaging effects
Reactants
a substance that takes part in and undergoes change during a reaction.
Products
In chemistry, a product is a substance that is formed as the result of a chemical reaction.
Hydrogen
a colourless, odourless, highly flammable gas, the chemical element of atomic number 1.
Oxygen
a colourless, odourless reactive gas, the chemical element of atomic number 8 and the life-supporting component of the air.
Water
a colourless, transparent, odourless, liquid which forms the seas, lakes, rivers, and rain and is the basis of the fluids of living organisms.
Copper
red-brown metal, the chemical element of atomic number 29.
Carbonate
a salt of the anion CO32−, typically formed by reaction of carbon dioxide with bases.
Carbon Dioxide
a colourless, odourless gas produced by burning carbon and organic compounds and by respiration. It is naturally present in air (about 0.03 per cent) and is absorbed by plants in photosynthesis.
burning:
combining a substance with oxygen in a flame
oxidation:
the chemical reaction involving the loss of electrons by a substance
