In a chemical reaction, what does the arrow mean?
Reacts to make
True or False: In a chemical reaction, atoms are created.
False. Rearranged, not created.
True or False: In a chemical reaction, the atoms are joined together in different arrangements after the reaction.
True
True or False: In a chemical reaction, the total number of each type of atom is the same after the reaction.
True
State the meaning of the word fuel.
A fuel is a substance that stores energy in a chemical store
Explain what a combustion reaction is.
A chemical reaction in which a substance reacts quickly with oxygen and gives out light and heat. Also called burning.
Methane (CH4) combusts with oxygen to produce carbon dioxide and water. Write down a balanced symbol equation for this reaction.
CH4 + 2O2 –> CO2 + 2H2O
What is meant by a thermal decomposition reaction.
When a single substance breaks down on heating to make more than one product.
When heated, copper carbonate reacts to form copper oxide and carbon dioxide. Write down a word equation for this reaction.
Copper carbonate –> copper oxide + carbon dioxide
When heated, copper carbonate reacts to form copper oxide and carbon dioxide. What is the name of this type of reaction?
Thermal decomposition
State what conservation of mass means
In a chemical reaction, the total mass of reactants is equal to the total mass of products.
Magnesium burns in oxygen to produce magnesium oxide. Write down a word equation, identifying the reactants and products
magnesium + oxygen (reactants) –> magnesium oxide (product)
