<h2>Answer:</h2>
At 189 K volume = 32.0 cm
As volume of gas is directly proportional to temperature.
As the temperature increase the volume of gas will also increase.
so
Volume at 1 K = 32/189
Volume at 242 K = 32/189 * 242 = 40.97 cm.
Gas occupy 40.97 cm volume at 242 K.
Answer:
When zinc is added to the solution of iron sulphate, the colour of iron sulphate solution changes. It is because zinc is more reactive than iron, it displaces iron from its solution of iron sulphate and a grey precipitate of iron and a colourless solution of zinc sulphate is formed.
