3. Chemistry

Mr Subba Rao

Ms Sridevi

Question no. 1:

Mole concept: In Chemistry, the unit mole is an important tool

when working with quantities. The amount of substance can be

measured in three units, namely, amu, gram and mole depending

upon the size of the substance. In order to make the drug from its

ingredients, someone has to figure out how much of each ingredient

is needed to react together to make the final drug.

Let us say that you went to the supermarket and bought the fruits

by dozen. One dozen is 12. Think that you bought one dozen apple, one

dozen banana and one dozen watermelon. Do you think one dozen of

these fruits weigh the same? No even though, they contain the same

number, their weights are different because they are different fruits.

Now you think this in terms of chemical substances. Well, if you take

6.022 x 1023 H atoms, 6.022 x 1023 Na atoms, 6.022 x 1023 Al atoms, do

you think all these have the same weight? No. Infact they weigh

differently because they are different substances. The weights of these

you can directly read from the modern Periodic table. Now answer the

following:

1. How many atoms and molecules are present in 100 gram S8?

2. Find the number of atoms of each type present in 90 gram of

glucose.

3. Calculate the number of electrons, protons and neutrons present in

3.2 gram of Oxygen gas.

4. Calculate the mass of one molecule of water molecule.

5. Calculate the percentage composition of each element in cane sugar

(C12H22O11).

Question no: 2

1. Write symbols, atomic numbers and atomic masses of 1-20 elements in

the periodic table.

2. Express the following reaction in the form of chemical equation and

then balance these equations.

A) Magnesium ribbon is burnt in a jar containing nitrogen gas when a

white powder of magnesium nitride is obtained.

B) Sodium hydroxide reacts with sulphuric acid to form sodium

sulphate and water.

3. Give an example of a metal which

a) Is a liquid at room temperature.

b) Can be easily cut with a knife

c) Is the best conductor of heat

d) Is the poorest conductor of heat.

4. A copper coin is kept immersed in a solution of silver nitrate for some

time. What will happen to the coin and the colour of the solution? Give

the reaction involved, if any.

5. Draw the structures of the following compounds: Ethanoic acid,

bromopentane, butanone, hexanal.

6. Match the reactions given in column (A) with the names given in

column (B).

Column (A) Column (B)

a) CH3OH + CH3COOH H+ CH3COOH + H2O

b) CH2=CH2 + H2 Ni

CH3-CH3 c) CH4 + Cl2

sunlight CH3Cl + HCl

d) CH3COOH + NaOH CH3COONa + H2O

i) Addition reaction ii) Substitution reaction iii) Neutralisation reaction iv) Esterification reaction

7. A compound X (molecular formula, C2H4O2) reacts with Na-metal to

form a compound Y and evolves a gas which burns with a pop sound.

Compound X on treatment with an alcohol A in presence of an acid

forms a sweet smelling compound Z (molecular formula, C3H6O2). On

addition of NaOH to X, it also gives Y and water. Z on treatment with

NaOH solution gives back Y and A. Identify X,Y,Zand A. write down the

reactions involved.

8. Give one example each of the compounds having the following

functional groups. Also give their names. Aldehyde group, Alcoholic

group, Carboxylic acid, Ester group, Keto group.

9. The number of electrons, protons, and neutrons in the three elements

X,Y and Z are given below:

Element Electrons Protons Neutrons

X 8 8 8

Y 10 10 10

Z 12 12 12

Choose the element which represents an atom of inert gas, which

represents an atom of a non metal, which has 2 electrons in M shell.

10. Four elements A,B,C and D along with their electronic configurations are

given below:

Elements : A B C D

4. Mathematics

Teachers Name:

I.Srinivas

K.Vijayalakshmi,

D.Nagajyothi.

ii) Which two elements belong to the same group?

iii) Which two elements belong to the 18th group?

iv) Which element out of A and C is more reactive and why?
