Answer: true
Explanation: For about 2000 years, people accepted Aristotle's idea that all matter is made up of just four elements: earth, air, water, and fire. Starting about 500 years ago, scientists began discovering all of the elements that are known today
The reaction you describe in words is:
KCl + AgCH3CO2 → AgCl + KCH3CO2
This type of reaction is known as a "double replacement reaction" aka "double displacement reaction" aka "metathesis reaction." A double replacement reaction is a chemical reaction where two reactant ionic compounds exchange ions to form two new products compounds with the same ions.
Answer
There is nothing like viscosity in solid because most of the solids usually have a rigid body. This is due to strong intermolecular forces. And it is due to this strong force between the molecules that they are unable to move and they remain fixed at their position. Some solids such as graphite which have layered structure, don't possess the property of viscosity, because of the strong force between the layers.
Explanation:
Viscosity is the property of a fluid that opposes the relative motion between two surfaces of the fluid that are moving at different velocities. In simple terms, viscosity means friction between the molecules of fluid.
FOR EXAMPLE
water is "thin", having a low viscosity, while vegetable oil is "thick" having a high viscosity
