Journey Inside the Atom (Structure of the Atom)
What is an atom?
The smallest basic unit of matter that makes up every element and chemical substance.
What are subatomic particles? Name the three main subatomic particles.
Particles smaller than an atom that form its internal structure. The three main particles are electrons, protons, and neutrons.
Define an electron and state its relative charge and mass.
A negatively charged subatomic particle found outside the nucleus. Its relative charge is...

Q1 Graphically show that an increase in investment in the economy results in a
Ans Graphical Demonstration: Increase in Investment and Proportionate Increase in Income
In the simple Keynesian model, national income is determined by aggregate expenditure. Assume a closed
economy with no government and no foreign trade.
Equilibrium condition: Y = C + I.
Let C = a + bY. When autonomous investment rises by ΔI, aggregate expenditure rises.

1. Functional Dependency (FD)
A functional dependency A → B means: if you know the value of attribute A, you can always determine the value of attribute B. In other words, no two rows can have the same A value but different B values.
Example:
In a table Student(StudentID, Name, Email):StudentID → Name, Email
(Given a StudentID, the Name and Email are always uniquely determined.)
A relation is in BCNF if, for every functional dependency X → Y, X is a superkey

HCl.
Theory:-
Titration of strong acid and strong base involves neutralization
reaction.
NaOH + HCl → NaCl + H2O
During titration pH of the solution taken in the conical flask changes as
the other solution is added from the burette. If NaOH is added from
the burette and HCl is taken in the conical flask, during the titration pH
of the solution in the conical flask will increase.
Procedure:-
1. Take a clean burette and rinse it with 0.1 M NaOH solution and
then
EPITELIU sunt ţesuturi care acoperă organismul, căptuşesc cavităţile sale şi formează parenchimul unor organe (glande).
Ţesutul epitelial poate fi caracterizat din 3 puncte de vedere: Histogenetic, trei foiţe embrionare, ectoderm, endoderm şi mezoderm. Funcţional, ţesuturile epiteliale sunt formate din celule adaptate rolului de protecţie, secreţie, absorbţie şi senzorial. Morfologic, ţesutul epitelial este singurul ţesut "pur" alcătuit predominant din celule, strâns unite între
