Thou art more lovely and more temperate.
Rough winds do shake the darling buds of May,
And summer's lease hath all too short a date.
Sometime too hot the eye of heaven shines,
And often is his gold complexion dimmed;
And every fair from fair sometime declines,
By chance, or nature's changing course, untrimmed;
But thy eternal summer shall not fade,
Nor lose possession of that fair thou ow'st,
Nor shall death brag thou wand'rest in his shade,
When in eternal lines to Time thou grow'st.
So long as men can breathe, or eyes can see,
So long lives this, and this gives life to thee.

vacations.
Group Activity:
Students with the below mentioned roll numbers need to collaborate and work upon the
following questions.
GROUP A: Poem Writing

ART INTEGRATION
(i) A Mandala is a Sanskrit word for ‘circle’ is a geometric design that holds a great
deal of symbolism in Hindu and Buddhist cultures. Mandalas are believed to
represent different aspects of the universe and are used as instruments of
meditation and symbols of prayer. In their most basic form mandalas are circles
contained within a square and arranged into sections that are all organized around
a single, central point.
To understand Mandala Art, its meaning, use of circles, polygons, lines and symmetry bring
out the artist in you and draw a beautiful Mandala art on an A3 size sheet using only
compass and ruler. Make a short video also (1-2 minutes) to explain the mathematical
association in it.

Answer the questions on the basis of your understanding of the following
paragraph and the related studied concepts.
1. Redox reactions involves both oxidation as well as reduction. If we cut an
apple, it turns reddish brown after some time because Fe2+ present in
apple gets converted into Fe3+ by loss of electrons. Oxidation is a process
in which loss of electrons takes place. Oxidation is carried out with the
help of oxidising agent which can give O2 or remove hydrogen or can gain
electrons. Non-metals are good oxidising agents, KMnO4, K2Cr2O7 are
also good oxidising agent in acidic medium. Combustion is oxidation
reaction. Reduction involve gain of electrons. Reducing agent can add H2
or remove O2 or can lose electrons. Metals are good reducing agents.
Reducing agents are used in extraction of metals.
(i) Fe2O3(s) + 3CO(g) → 2Fe(s) + 3CO2(g)
Name the oxidising and reducing agent in the above reaction.
(ii) H2S(g) + Cl2(g) → 2HCl(g) + S(g)
Name the substances which are getting oxidising and reduced.
(iii) Mg(s) + 2H+ (aq) → Mg2+(aq) + H2(g)
Why is Mg acting as reducing agent and H+ ions are oxidising agent ?
(iv) Cr2O3 + 2Al → Al2O3 + 2Cr
What are types of above reaction?
