Welcome to your Chemical Reaction Name Email What happens to atoms during a chemical reaction? Atoms are dissolved Atoms are created Atoms are rearranged Atoms are destroyed None True or false? Dissolving is an example of a chemical reaction True False None Which of these is an example of a chemical reaction? Water freezing Cooking Ice melting Water boiling None True or false? It is usually very hard to reverse a chemical reaction True False None What type of chemical reaction releases energy from a fuel? Combustion Neutralisation Decomposition None What evidence can you see that a chemical reaction is taking place? Bubbling insoluble Dissolving None When sugar is added to water and stirred, does a chemical reaction occur? yes no None What is the name of the compound which is made when iron reacts with sulfur? Iron sulfide Sulfur dioxide Hydrogen sulfide None What is the name of the compound which is made when carbon reacts with oxygen? Carbon dioxide oxygen carbide water None Which is the correct chemical word equation to show the reaction of carbon with oxygen? Carbon dioxide → carbon + oxygen Carbon + oxygen = carbon dioxide Carbon + oxygen → carbon dioxide None What is meant by the term ‘displacement reaction’? When a fuel reacts with oxygen and releases energy When a more reactive element takes the place of a less reactive element in a compound When a reaction absorbs energy from the surroundings None What is being described here? “A pure substance which is made from only one type of atom, listed on the periodic table” Element Mixture Compound None Which is the most reactive metal shown in this reactivity series? Platinum Potassium Iron None What will be produced if magnesium metal is added to a solution of copper sulfate? Copper magnesium plus sulfur Sulfur dioxide, copper and magnesium Copper plus magnesium sulfate None In industry, which metal element is used to displace valuable copper from a solution containing waste copper compounds? Iron Sodium Platinium Potassium None Which is the correct symbol equation for the reaction between magnesium and copper sulfate? Mg(s) + CuSO4(aq) → Cu(s) + MgSO4(aq) Mg(s) + CaSO4(s) → Ca(s) + MgSO4(aq) Cu(s) + MgSO4(aq) → Mg(s) + CuSO4(aq) None What will happen if silver metal is added to a solution of zinc chloride? The silver will displace the zinc There will be no reaction There will be an explosion None Carbon is more reactive than zinc but less reactive than aluminium. Which of these metals CANNOT be extracted by heating its oxide with carbon? Magnesium Tin Copper Lead None Chlorine is more reactive than bromine and iodine is less reactive than bromine. Which of these combinations will result in a displacement reaction? Iodine + sodium chloride Bromine + potassium chloride Bromine + potassium iodide None Which is the correct equation for the reaction of chlorine with potassium bromide? chlorine + potassium bromide → chlorine bromide + potassium chlorine + potassium bromide → bromine + potassium chloride chlorine + potassium bromide → bromide + potassium chlorine None 1 out of 20 Time's upYou cannot switch tabs while taking this quiz!You are not allowed to switch tabs violation has been recorded.you cannot minimize full screen mode!You are not allowed to minimize full screen while taking this quiz, violation has been recorded.Access denied!
