Refrigerant may be of four type such as R-22, R 410A, R- 290, R-417 A
The refrigerator R410A having standing pressure of about 260 psi whereas saction pressure of about 120 to 130 psi and discharge pressure of about 450 to 500 psi.
Refrigerant R-410 is a cooling machine consists of equipments and chillers for air conditioning purpose along with coolant gas. This refrigerant have high cooling capacity which consumes less power. The suction pressure is 118 psi and discharge pressure is 400 psi.

Answer:
The missing reagents are.
Potassium + Iodine =<u> Potassium iodide</u>
<u>Calcium</u> + oxygen = Calcium oxide
Beryllium +<u> Bromine</u> = Beryllium bromide
<u>Copper + Oxygen</u> = Copper oxide
Explanation:
The balanced equation can be written as:
1.Potassium + Iodine =<u> Potassium iodide</u>
![2K(s)+I_{2}(s)\rightarrow 2KI(s)](https://tex.z-dn.net/?f=2K%28s%29%2BI_%7B2%7D%28s%29%5Crightarrow%202KI%28s%29)
Here K = potassium
I2 = Iodine
KI = potasssium iodide.
2.<u>Calcium</u> + oxygen = Calcium oxide
![2Ca(s)+O_{2}(g)\rightarrow 2CaO(s)](https://tex.z-dn.net/?f=2Ca%28s%29%2BO_%7B2%7D%28g%29%5Crightarrow%202CaO%28s%29)
Ca = calcium
O2 = oxygen
CaO = Calcium Oxide
3.Beryllium +<u> Bromine</u> = Beryllium bromide
![Be(s)+Br_{2}(g)\rightarrow BeBr_{2}(s)](https://tex.z-dn.net/?f=Be%28s%29%2BBr_%7B2%7D%28g%29%5Crightarrow%20BeBr_%7B2%7D%28s%29)
Here,
Be = beryllium
Br2 = bromine
BeBr2 = Beryllium Bromide
4. Copper + Oxygen = Copper oxide
![2Cu(s)+O_{2}(g)\rightarrow 2CuO(s)](https://tex.z-dn.net/?f=2Cu%28s%29%2BO_%7B2%7D%28g%29%5Crightarrow%202CuO%28s%29)
Cu = Copper
O2 = oxygen
CuO = Copper Oxide
