Properties of substances W, X, Y and Z are listed below:
W: A liquid metal
X:A liquid non-metal
Y: Gaseous non-metal
Z: A non-metal which conducts electricity.
Iron, iodine, hydrogen and oxygen
Gold, sulphur, chlorine and hydrogen
Copper, phosphorus, nitrogen and carbon

An unknown metal X when placed in copper sulphate solution, red brown pieces of copper fall to the bottom of the test tube.When metal X is placed in aluminium sulphate solution, no change is observed. Metal X can be
Sodium
Potassium
Iron
Calcium
Substance X reacts with dilute HCI violently, V reacts slowly while Z does not react at all. X, Y and Z could be respectively
Cu, Al, Fe
Al, Na, Cu
Na, Cu, Fe
K, Al, Cu

Which of the following statements is incorrect?
Gold and silver are the most malleable and ductile metals.
All metals are hard and strong.
Mercury and gallium are metals which exist in liquid state at room temperature.
Most of the metals have high specific gravities.
What will happen if you keep a solution of copper sulphate in an iron container for a few days? What is the reason for your observation?
The surface of iron container will develop a green layer due to corrosion caused by copper sulphate.
Copper metal will be deposited in iron container since copper is more reactive than iron.
Nothing will happen since no reaction takes place between copper sulphate and iron.
Holes will be formed in the container since iron is more reactive than copper hence iron displaces copper from a solution of copper sulphate.
Kanika takes a burning substance and collects the evolved vapours in a test tube, making sure that they do not escape.A small amount of water is added to the test tube. To the solution obtained, a few drops of blue litmus solution are added. The litmus solution turns red. Which of the following could be the burning substance?
Mg
S
Na
Fe

(i) X is stored under kerosene.
(ii) Y catches fire on exposure and stored in water.
(iii) Z reacts with steam.
Na, Mg, Cu
Na, P, Fe
Cu, Zn, K
Zn, Cu, Na
