Make a grade 9 chemistry practice test with these concepts: Reactants, Products, Precipitate, Word equation, Chemical equation, Aqueous, Endothermic, Exothermic, Concentration, Surface area, Catalyst, Enzyme, Corrosion, Combustion, Bohr diagram, Valence shell, Valence electron, Molecular compound, Ionic compound, Ionic bond, Molecular bond, Diatomic, Covalent. Include the ability to determine whether a chemical reaction has occurred, know the 7 pieces of evidence for a chemical reaction, read a chemical equation with states, understand energy in chemical bonds, speed up/slow down reactions, understand corrosion and combustion equations, draw Bohr diagrams for the first 20 elements, and differentiate between ionic and molecular compounds and their properties.
Understand the Problem
The question is asking to create a 60-question practice test for grade 9 chemistry covering various concepts such as reactants, products, types of reactions, chemical bonds, and Bohr diagrams. The test should assess students' understanding of key chemistry topics and their ability to apply them.
Answer
Include definitions, equations, diagrams, properties, and reaction conditions in the test.
Designing a comprehensive Grade 9 chemistry practice test involves including various question types, such as multiple choice, short answers, and problems, all based on the key concepts and skills listed. These include definitions, equations, diagrams, properties, and reaction conditions.

More Information
Such a test can assess understanding by asking students to identify the signs of a chemical reaction, differentiate between types of compounds, and calculate the concentrations. Including drawing activities like Bohr diagrams can test the understanding of atomic structures.
Tips
Students often confuse molecular compounds with ionic compounds. Clarify the differences in bonding and properties. Pay close attention to state indicators in chemical equations.
