A four carbon atoms containing neutral oranic compoud X reacts with sodium metal to evolve a gas which burns with a 'pop' sound . Another foiur carbon atoms containing carbon compoound reacts with sodium hydrogencrbvonate to evolvbe a gas which truns lime water milky when compounds X and Y are heated together in the presence of al little of concentrated suphuric acid then a new compound Z is formed. (a) What is compound X? Also wrte its formula. (b) What is compound Y? Also write its formula. (c ) What is compound Z? Also write its formula. (d) What type of smell is given by compound Z? (e ) What is the general name of compunds like Z? (f) What is the general name of the reaction which takes place between X and Y to form Z?

Mr. Firoze is a retired man who lives in a big house. He has recently replaced all the filament-type bulbs in his house by CFls. His wife and children have a habit of keeping the lights and fans on (even when there is no one in the room) but Mr. Firoze keeps on going to every room periodically to switch them off. A few days back Mr. Firoze had purchased a device which can cook rice and dal without using any usual fuel. He has also installed an equipment on the roof of his house to obtain hot water. Mr. Firoze uses bicycle for short distances like going to nearby market, instead of scooter or car. (a) What is CFL ? Why has Mr. Firoze replaced all the filament-type bulbs in his big house by CFLs ? (b) Why does Mr.Firoze keep switching off lights and fans when no one is in the rooms ? (c) Name the device which Mr. Firoze has purchased to cook rice and dal without using any usual fuel ? (d) Name the equipment which Mr. Firoze has installed on the house-roof to obtain hot water ? (e) Why does Mr. Firoze use bicycle for going through short distances ? (f) What values are displayed by Mr. Firoze by all the above actions ?

One day Vabhav was performing experiments in the science laboratory based on the of chemical combination. Just then his chemistry teacher, Mr. Rajeev, came into the laboratory. Mr. Rajeev told Vaibhav that in an experiment conducted byby a class IX student when 10.6 g of sodium carbonate was reacted with 12.0g of ethanoic acid in a closed flask, then 16.4 g of sodium ethanoate, 4.4 g of carbon dioxide and an unknown mass of substances Y were produced. Mr. Rajeev asked Vaibhav to make use of this information and answer the following questions : (a) Write a word equation for the reaction which takes place on reacting sodium carbonate and ethanoic acid (b) Which is the substance Y which is produced in this reaction ? (c) What mass of substance Y is produced in this reaction ? (d) Which law of chemical combination has been made use of in calculating the mass of substance Y ? State this law (e) What values are displayed by Vaibhav in this eposide ?

Salt water contains n sodium ions (Na+) per cubic meter and n chloride ions (CI-) per cubic meter. A battery is conneted to metal rods that dip into a narrow pipe full of salt water. The cross sectional area of the pipe is A. The magnitude of the drift velocity of the sodium lons is V_(Na) and the megnitude of the drift velocity of the chloride ions is V_(CI) Assume that N_(Na)gtC_(CI) (+e is the charge of a proton). What is the magnitude of the ammeter reading ?

Lithium only forms monoxide when heated in oxygen. Sodium forms monoxide and peroxide in excess of oxygen. Other alkali metals form superoxide metals superoxide with oxygen i.e., MO_(2) . The abnormal behaviour of lithium is due to small size. The larger size of higher metals also decides the role in formation of superoxide. All the three anions abstract proton from water. The three anions are raleted to each other as follows: underset("oxide ion")(O_(2)^(2-)overset((1)/(2)O_(2))(to)underset("peroxide ion")(O_(2)^(2-))overset(O_(2))(to)underset("superoxide ion")(2O_(2)^(-)) Q. Which compounds will liberate oxygen when reacts with ice cold water?
