Examples of chemical properties include toxicity, flammability and chemical stability. Measuring these properties involves observing their effects on laboratory animals, testing with a flame or observing changes over time. In each instance, a chemical change occurs.Know More
Chemical properties of matter are those properties that are observable or measurable only when a chemical reaction or chemical change occurs. They are not the physical properties, which an observer determines by viewing or touching a sample. In order for chemical properties to become apparent, there has to be an alteration in the sample.
Chemical properties are apparent when changes take place. Hydrogen gas ignites and explodes, which is a chemical change. Many metals react with acids, including zinc, which reacts by releasing hydrogen gas.
Potassium cyanide and sugar are both white crystalline structures that are similar in appearance. However, their physical properties are not an implication of the chemistry that takes place if ingested. Sugar provides energy for cells after digestion, while potassium cyanide is highly toxic.
Scientists use chemical properties in many ways. They help predict chemical reactions of the material. These properties help to predict what occurs in a chemical reaction. They also help to classify compounds and determine real-world applications for them.Learn more about Chemistry
Sodium chloride is composed of approximately 60 percent chloride and 40 percent sodium elements. Commonly known as table salt, it is a white-colored or transparent water-soluble crystalline solid with the chemical symbol NaCl.Full Answer >
Baking soda, otherwise known as sodium bicarbonate, has the chemical properties of not being flammable, being easily decomposed by acids, starting to decompose in water solution at approximately 20 degrees Celsius and an increasing alkalinity in solution as it is heated or stirred. Baking soda is used for cleaning and cooking and is effective at putting out certain types of fires.Full Answer >
Potassium readily loses the single electron in its outer valence, causing it to react very energetically to substances that strongly attract electrons. Potassium is a silver colored metal that tarnishes rapidly when exposed to air because of the oxygen and water vapor.Full Answer >
Bananas possess marked nutritional value. They supply a large quantity of carbohydrates to the human body and an unripe banana has more starch than sugars. The fiber extracted from the pseudostem and peduncle parts of banana plants constitutes cellulose, hemicellulose, pectin and lignin.Full Answer >
