When a sodium atom transfers an electron to a chlorine atom, forming a sodium cation (Na+) and a chloride anion (Cl-), both ions have complete valence shells, and are energetically more stable. The reaction is extremely exothermic, producing a bright yellow light and a great deal of heat energy.
Q1: Gases diffuse easily through amorphous or porous solids.
Q2:All changes in phase are called change in state of matter.
Answer:
Explanation:
Gases diffuse easily through amorphous or porous solids. Usually solids are densely packed with no space. But porous solids can help in diffuse gas into them. Due to the vacancy present in these solids, gas can easily diffuse through these types of solids.
Similarly, the phase changes lead to change in the state of matter. As the basic of change in phase leads to change in its state from solid to liquid or from liquid to gas or vice versa. So change in state of matter will occur in any change in phase.
