b) The following diagram displays a chemical reaction. Observe carefully and answer the following questions
(i) Identify the type of chemical reaction that will take place and define it. How will the colour of the salt change?
(ii) Write the chemical equation of the reaction that takes place.
Pratyush took sulphur powder on a spatula and heated it. He collected the gas evolved by inverting a test tube over it, as shown in the figure

6. Prepare any one Project given below:
a) Answer the following:
A man went door-to-door posing as a goldsmith. He promised to bring back the glitter of old and dull gold ornaments. An unsuspecting lady gave a set of gold bangles to him which he dipped in a particular solution. The bangles sparkled like new but their weight was reduced drastically. The lady was upset but after a futile argument, the man beat a hasty repeat. Can you play the detective to find out the nature of the solution he has used?
1) Gold is a very precious metal. Pure gold is very soft it is therefore not suitable for making jewellery. It is alloyed with either Silver or Copper to make it hard. But sometimes jewellers mix a large quantity of copper and silver in gold to earn more profit.
a) What precautions should you take while purchasing gold jewellery?
b) Why does the Government insist on purchasing hallmarked jewellery?
2) Corrosion is a serious problem. Every year an enormous amount of money is spent to replace damaged iron. What steps can be taken to prevent this damage?
3) Mercury is the only metal found in the liquid state. It is largely used in thermometers to measure the temperature. But mercury is a very dangerous metal as its density is very high. What two precautions you would take while handling the equipment containing Mercury?
b) Make two cylindrical cardboard formers of diameter 1 inch and 2 inches and length 6inch closely
wound coils using insulated copper wire taking out of tapping after 50 turns, 100 turns, 250
Turns on each format. Now place a magnate needle at an appropriate distance.
Take the first coil. Connect its 50 turns across a battery and note the deflection of the magnetic needle.
Repeat observations with 100 turns, 200 turns etc.
Make similar observations using the second coil.
Now insert 6-inch long iron nails inside the coil and repeat the experiment. Now answer the following questions:
1. What is the effect of increasing the number of turns on the strength of the electromagnet?
2. What is the effect of increasing the area of cross-section on the strength of the Electromagnet?
3. What is the effect of using a soft iron core on the strength of the electromagnet?
4. What is the effect of increasing current on the strength of elec
