FAQs : CBSE Sample Papers for Class 11 Chemistry

Q1: What are the fundamental concepts of chemistry?

A1: The fundamental concepts of chemistry include matter and its nature, the structure of the atom, the periodic table, chemical bonding, states of matter, thermodynamics, and chemical equilibrium.

Q2: What is the significance of the periodic table in chemistry?

A2: The periodic table organizes elements based on their atomic number, electron configuration, and recurring chemical properties. It helps in predicting the properties of elements and understanding their relationships.

Q3: Explain the different types of chemical bonding.

A3: Chemical bonding includes ionic, covalent, and metallic bonding. Ionic bonding involves the transfer of electrons, covalent bonding involves the sharing of electrons, and metallic bonding involves a sea of delocalized electrons in a lattice of positive ions.

Q4: What are the different states of matter, and how do they differ?

A4: The three primary states of matter are solid, liquid, and gas. Solids have a fixed shape and volume, liquids have a fixed volume but take the shape of their container, and gases have neither a fixed shape nor volume.

Q5: Explain the concept of stoichiometry.

A5: Stoichiometry deals with the quantitative relationships between reactants and products in chemical reactions. It involves calculations based on the balanced chemical equation, such as mole ratios, mass-to-mole conversions, and stoichiometric calculations.
