Which substance will not conduct electricity?
aluminium
copper
plastic
Steel
Which reaction shows an oxidation reaction?
C + O2 → CO2
CaCO3 → CaO + CO2
CaO + 2HCl→ Ca Cl2 + H2 O
N2O4 → 2NO2
W,X,Y and Z are metals. Some of the properties of these metals are listed
1. Only W and Z can be extracted by reduction of their oxides with carbon
2. Only X will react iwth cold water
3. Only Z can be found 'native' (not combined with any other element)
What is the correct order of these metals in the reactivity series (least reactive first)
X,W,Y,Z
X,Y,W,Z
Z,W,Y,X
Z,Y,W,X
Which statement about rusting is not correct?
Only oxygen is needed for rusting
Painting can stop iron gates from rusting
Rust in hydrated iron (III) oxide
Salt can speed up the rate of rusting.
Which equation shows reduction
Fe2+ + e- → Fe3+
Fe2+ → Fe3+ + e-
Fe3+ + e- → Fe2+
Fe3+ → Fe2+ + e-
A student investigated the reaction of four metals R, S,T and U with solutions of their salts.
What is the order of reactivity?
R → S → U → T
R → T → U → S
S → U → T → R
U → R → T → S
Some reactions of three metals and their oxides are shown. What is the order of reactivity - least reactive first?
S,T,U
S, U, T
T,S, U
U , T, S
An example of a redox reaction is shown.
Zn + Cu2+ → Zn2+ + Cu
Zn in the oxidising agent and oxidises Cu2+
Zn in the oxidising agent and reduces Cu2+
Zn in the reducing agent and oxidises Cu2+
Zn in the reducing agent and reduces Cu2+
A steel bicycle which has been left outdoors for several months is starting to rust. What would not reduce the rate of corrosion?
Remove the rust and paint the bike
Remove the rust and store the bicycle in a dry shed
Remove the rust and wipe the bicycle with a clean, damp cloth
Remove the rust and wipe the bicycle with an oily cloth
(a) iron is iron that has been coated in a layer of zinc
ZInc, magnesium or aluminium blocks are attached to metal hulls or keels of ships to prevent the iron/steel from rusting. These blocks are called (a) anodes
Oxidation is (a) of electrons
Metals will react with water or acid if they are more reactive than (a)
Potassium will react violently with water making a (a) flame
Coating iron with paint, oil, grease or a less reactive metal is called a (a) method
