The Oort cloud sometimes called the Öpik–Oort cloud it was first described in 1950 by Dutch astronomer Jan Oort
c - the molarity, n - the number of moles, V - the volume of the solution
First calculate the number of moles of AgNO₃ in the solution.
The volume is
.
The molarity:
.
The molarity is
0.016 mol/L.
Answer: solid
Explanation: Chemical reactions are those which involve rearrangement of atoms.
Chemical changes are accompanied by following changes:
1) Absorption or release of heat
2) Change in color
3) Formation of gas bubbles
4) Formation of a solid product called as precipitate
Example of formation of precipitate or solid in chemical reaction:
The liquid to solid process using the particle theory is as below
- The process that involve change of liquid to solid is known as Freezing
- It involve change from a high energy state to lower energy
- The constant temperature at which a liquid change to solid by giving out heat energy is called freezing point of the liquid
- when liquid are cooled the thermal energy of particles decrease.
- The cohesive forces between the particles strengthen to such extent that particles can have relative motion with each other and they occupy the fixed position, thus liquid is converted to solid
