Salt are mostly ionic compounds. A typical feature of ionic compounds is that the molecules form a network of ions called a crystal lattice. This network is formed due to electrostatic attraction of the ions. The positive ions get attracted to the negative ions surrounding it and vice versa. Thus, salt has a crystal like structure, which remains even if the salt has just evaporated.
What else can I help you with?
Is hanging wet towels a chemical or physical change?
It is a physical change. Being changed from wet to dry.
Is heat energy being added or removed during the process of evaporation?
In condensation heat is removed In evaporation heat is added
Is gasoline being evaporated a chemical reaction?
No. Evaporation is a physical process.
What is the process of excess water being evaporated?
The phenomenon is called evaporation.
Is spilled gasoline drying a chemical or physical change?
Gasoline evaporation is a physical process.
What name is given to the process of enlarging crystals by adding particles?
The process of enlarging crystals by adding particles is called crystal growth. This technique is often used in material science and can be modified to control the size, shape, and properties of the crystals being formed.
What process results in moisture being added to unsaturated air?
Evaporation and Sublimation
Why you consider evaporation is heat-absorbing process has a cooling effect?
the hot air is being lifted or released into the air
What is an inorganic process?
A process of something being formed that is not from another thing that was alive at one point.
Does a crystal being hit by a hammer contain ionic or metallic bonds?
A crystal being hit by a hammer is more likely to contain ionic bonds, as these bonds are formed between ions of opposite charges. Metallic bonds are found in metals, where electrons are shared and contribute to the overall structure and properties of the material.
What is the drying up of water by the sun called?
The process of water being turned into water vapor by the sun is called evaporation.
Is it physical or chemical change a gas spread on pavement quickly disappears?
The gas spreading on the pavement quickly disappearing is a physical change. This is because no new substances are being formed, and the gas is simply diffusing into the air, which is a reversible process.
