Group the characteristics of the give substance according to their physical (extensive or intensive) or chemical properties. CHARACTERISTICS OF SOME PHYSICAL PROPERTIES |CHEMICAL PROPERTIES SUBSTANCES INTENSIVE EXTENSIVE 2. NacI with a mass of 37.9 g is colorless, odorless, and salty solid crystals. It has melting point of 801 degree Celsius. When dissolved in 100 mL water, it conducts electricity. It reacts with silver nitrate to form a white precipitates. It also react with water to form chlorine gas, hydrogen gas, and sodium hydroxide.
States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.
