FAQs on Mind Map: Some Basic Concepts of Chemistry - Chemistry Class 11 - NEET

1. What is chemistry?
Ans. Chemistry is a branch of science that deals with the composition, structure, properties, and changes of matter. It involves the study of the elements, compounds, and reactions that occur between them.
2. What are the three states of matter?
Ans. The three states of matter are solid, liquid, and gas. Solids have a fixed shape and volume, liquids have a fixed volume but can change shape, and gases have neither a fixed shape nor volume.
3. What is the difference between an element and a compound?
Ans. An element is a substance made up of only one type of atom, such as oxygen or gold. A compound, on the other hand, is a substance made up of two or more different types of atoms chemically bonded together, such as water (H2O) or carbon dioxide (CO2).
4. What is a chemical reaction?
Ans. A chemical reaction is a process in which one or more substances (reactants) are transformed into new substances (products) through the breaking and forming of chemical bonds. Chemical reactions involve the rearrangement of atoms to create different molecules.
5. How do you balance a chemical equation?
Ans. To balance a chemical equation, you need to ensure that the number of atoms of each element on both sides of the equation is equal. This is achieved by adjusting the coefficients (numbers in front of the chemical formulas) of the reactants and products. The law of conservation of mass states that matter is neither created nor destroyed in a chemical reaction, so the total number of atoms of each element must be the same before and after the reaction.
