•When substances change their properties such as change of state, solubility, shape, or form, these changes are called physical changes. •When a new substance is formed with different compounds and properties, this change is called a chemical change. •And, the reaction that makes this change is called a chemical reaction. Physical changes Chemical changes No …
Hydrocarbons• Carbon atoms bond to each other by single, double, and triple bonds. • Saturated hydrocarbons contain only single bonds. • Unsaturated hydrocarbons contain at least one double or triple bond. Refining Hydrocarbons• Fractional distillation involves boiling petroleum and collecting each group of components as they condense at different temperatures. • Fractional distillation towers do …
Atoms consist of three basic particles: protons, electrons, and neutrons. The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge). The outermost regions of the atom are called electron shells and contain electrons (negatively charged). mass number: The sum of the number of protons and the number of neutrons in …

Let’s try to understand the factors affecting the rate of a chemical reaction. We are going to check three factors: concentration, temperature, and surface area. We are doing an experiment of Acetic acid available in vinegar with the Sodium bicarbonate of baking soda. Acidic Acid (Ch3COOH) + Sodium bicarbonate (NaHCO3) -> CO2 (Carbon dioxide) + …
