The chemical formula of the compound formed between cobalt (III) and the bromide ion it would be CoBr3, if this compound exist !
No, the environment on Venus is not conducive to the sort of life that exists on Earth.
The compound TiCN4 does not exist. The chemical formula for compounds typically contains elements with known oxidation states that allow for stable bonding. In this case, a titanium compound with four carbon and nitrogen atoms bound to it would not be feasible.
The name would be nitrogen heptachloride. but the compound DOESN'T EXIST.
It would be trineon pentafluoride, but it likely does not exist.
Perchlorous acid does not exist as a stable compound; it is a hypothetical compound. Its formula would be HClO4.
