Given the descriptions or chemical formulas, students will use relative masses of elements in substance to calculate and determine the ratio of atoms of each element in a compound so as to determine percent composition or empirical formula.

This resource provides alternative or additional tier-one learning options for students learning about heat transfer, Chemistry TEKS (11)(B).

This resources allows students to explore the postulates of the Kinetic Molecular Theory in order to better understand why gas particles behave the way that they do.  

Given descriptions, diagrams, and chemical symbols of any element, students will show the arrangement of electrons in the outer-most energy levels by using Lewis valence electron dot structures.

Given descriptions, scenarios, or diagrams, students will use the formula for the ideal gas law to calculate pressure, temperature, volume, or moles of a gas.

Given laboratory investigation scenarios, students will determine the equipment that best fits the procedure.

Given descriptions, scenarios, or diagrams, students will use Avogadro’s constant to calculate the weight in grams of a single atom or molecule of a substance.

Given descriptions or chemical formula of a substance, students will convert between mass, moles, and particles for a sample of material.

Given descriptions or chemical formulas of the reactants and the products of chemical reactions, students will apply the law of conservation of mass and manipulate coefficients to balance chemical equations.

Given descriptions or illustrations of properties, students will determine whether the property is chemical or physical, and if it is physical, if it is intensive or extensive.

Given descriptions or specific element groups, students will use a Periodic Table to relate properties of chemical families to position on the table.
