Answer:
chemical reaction between those a b c it's a reaction which occurs when heating
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-

To answer this, we use Raoult's Law where the partial pressure is equal to the product of the fraction of the gas in the mixture and its total pressure. Also, we use Dalton's Law of Partial Pressure where the total pressure is equal to the sum of the partial pressure of the gases in the mixture.
Ptotal = 73.44 + 128.52 + 2.04 = 204 atm
201.96 = x (204)
x = 0.99
CaCO₃ → CaCl₂
Ca = 40, C = 12, O = 16, Cl = 35.5
100 →111
3 → x
x = 3.33g
