1.	Pratyush took sulphur powder on a spatula and heated it. He collected the gas evolved by invertinga test tube over it as shown in Fig. below : (a) What will be the action of gas on (i) dry litmus paper ?(ii) moist litmus paper ?(b) Write a balanced chemical equation for the reaction taking place
Answer» Solution : (a) Sulphur is a non-metal. Oxides of non-metals are ACIDIC. In this case sulphur DIOXIDE is produced which is acidic. (i) There will be no action of the GAS on dry litmus paper. (ii) Wet litmus paper will TURN red. (b) The balanced chemical equation can be written as under : `S(s) + O_2(g) to SO_2(g)`
