You’ll need to know about acids, bases, and salts, including their properties, pH scale, and common examples like sodium hydroxide and hydrochloric acid. Understanding neutralization reactions is super important. Then there’s metals and non-metals – their properties, reactivity series, and how we extract metals from their ores (metallurgy). Objective questions might ask you to identify a metal based on its properties or to predict the product of a reaction between a metal and an acid. Carbon and its compounds is a massive topic, covering allotropes of carbon (like diamond and graphite), the unique ability of carbon to form long chains and rings (catenation), homologous series, and functional groups. You'll encounter questions about naming organic compounds using IUPAC nomenclature and understanding concepts like saturated and unsaturated hydrocarbons. Don’t forget about periodic classification of elements – understanding the trends in properties across periods and groups, and the basis of the periodic table. Objective questions are perfect for testing recall of atomic numbers, electronic configurations, and the reasons behind the arrangement of elements. For instance, a question might ask you to identify the product of burning magnesium in air, or to determine the pH of a solution. You could be asked to state the valency of an element based on its position in the periodic table or to identify a functional group in a given organic molecule. These questions ensure you’re not just memorizing formulas, but understanding the logic behind chemical processes and the relationships between different elements and compounds. Building this knowledge base through objective questions is key to excelling in chemistry.

Biology: The Wonders of Life
