When two electrons are added to chlorine has, Cl2, each atom of Cl will receive one electron. Hence, the atoms becomes ions having a negative charge, Cl-
<h3>Ions</h3>
Ions are atoms or group of atoms possessing an electrical charge which may be positive or negative.
Negatively charged ions are formed when atoms accept or gain electrons. The negative charge is because there are more electrons than protons in the atom.
Negatively charged ions are usually formed by non-metals. For example, chlorine gas accepts two electrons to become 2 Cl-
Cl2 + 2e- ----> 2 Cl-
Therefore, when two electrons are added to chlorine has, Cl2, each atom of Cl will receive one electron. Hence, the atoms becomes ions having a negative charge, Cl-

An easy trick is to count the zeros.
Fe: 2 x 55.845 = 111.69
O: 3 x 15.9994= 47.9982
111.69 + 47.9982 = 159.69 g/mol
Answer:
Gas in motion : Vaporization
Examples of fluid flow :
- A river flowing down a mountain
- Air passing over a bird's wing
- Blood moving through a circulatory system
- Fuel moving through an engine.
Explanation:
nebula is an interstellar cloud of dust, hydrogen, helium and other ionized gases. although denser than the space surrounding them, most nebulae are far less dense than any vacuum created on earth – a nebular cloud the size of the earth would have a total mass of only a few kilograms. (wikipedia)
