Finish the following equation
magnesium + hydrochloric acid –>
magnesium chloride + hydrogen
Finish the following reaction
Magnesium + oxygen –>
Magnesium oxide
Finish the following word equation
magnesium + sulphuric acid –>
magnesium sulphate + hydrogen
Finish the following symbol equation for the reaction of zinc and hydrochloric acid
Zn + ____ –> ZnCl2 + ____
Zn + 2HCl –> ZnCl2 + H2
Predict whether the following would react explaining your reason.
Finish the equation if it reacts
Magnesium chloride + Zinc –>
Doesn’t react
as magnesium is more reactive than zinc
Predict whether the following would react explaining your reason.
Finish the equation if it reacts
Zn(NO3)2 + Mg –>
Reacts as magnesium is more reactive than zinc
–> Mg(NO3)2 + Zn
Predict whether the following would react explaining your reason.
Finish the equation if it reacts
Copper nitrate + iron
Reacts as iron is more reactive than copper
–> iron nitrate + copper
Predict whether the following would react explaining your reason.
Finish the equation if it reacts
Copper nitrate + iron
Reacts as iron is more reactive than copper
–> iron nitrate + copper
Predict whether the following would react explaining your reason.
Finish the equation if it reacts
Zinc chloride + calcium –>
Reacts as calcium is more reactive than zinc
–> Zinc + calcium chloride
What is a displacement reaction?
When a more reactive element replaces a less reactive element in a compound
Explain why copper can be extracted from its ore with carbon
as carbon is more reactive than copper
Write a symbol equation for the reduction of copper oxide with carbon
CuO + C –> Cu + CO
A 150g sample of copper ore contains 15g of copper. Calculate the percentage of copper in the ore.
15 ÷ 150 x 100
= 10%
