I guess it is gases
I think , coz it has its own shape

Answer:
Fe(CN)₂, FeCO₃, Pb(CN)₄, Pb(CO₃)₂
Explanation:
Cations (positively charged ions) can only form ionic bonds with anions (negatively charged ions). However, you can't just simply put one cation and one anion together to form a compound. Each compound needs to been neutral, or have an overall charge of 0. When cations and anions do not have charges that perfectly cancel, you need to modify the amount of each ion in the compound.
1.) Fe(CN)₂
-----> Fe²⁺ and CN⁻
-----> +2 + (-1) + (-1) = 0
2.) FeCO₃
-----> Fe²⁺ and CO₃²⁻
-----> +2 + (-2) = 0
3.) Pb(CN)₄
-----> Pb⁴⁺ and CN⁻
-----> +4 + (-1) + (-1) + (-1) + (-1) = 0
4.) Pb(CO₃)₂
-----> Pb⁴⁺ and CO₃²⁻
-----> +4 +(-2) + (-2) = 0
Non metal atoms got this from google btw
Answer: The total pressure will be 1,11,720 torr.
Explanation:
Partial pressure of nitrogen gas.
(1atm = 760 torr)
Partial pressure of oxygen gas,
Total pressure, in torrs, of the scuba gas mixture = 40280 + 71440 torr =111,720 torr
Hence , the total pressure in scuba gas mixture is 111,720 torr.
Calcium Chloride because it is a type 1 so the the anion ends with -ide
