It contains a lone pair of electrons. Hence, it can donate it thereby ,its a base. The tendency to donate the electron pairs can determine the basicity of a base. Therefore, PF3 is less basic than PH3.
The systematic name for IF3 is iodine trifluoride.
The systematic name of K2SeO4 is potassium selenate.
The systematic name for COSO3 is carbonyl sulfite.
The systematic name for gypsum is calcium sulfate dihydrate.
The systematic name of barium chloride is barium dichloride.
It is called Phosphorous Trihydride. Also known as phosphine.
It is technically PH3, and it is called Phosphine
The systematic name for IF3 is iodine trifluoride.
The systematic name for KCl is potassium chloride.
The systematic name of K2SeO4 is potassium selenate.
The systematic name for COSO3 is carbonyl sulfite.
You might think trigonal planar, but it's actually trigonal pyramidal. Remember that phosphorus (like nitrogen) ends up with a lone pair when it bonds to three things covalently. That lone pair causes a lot of distortion and you end up with the pyramid shape.
The systematic name for ICI3 is trichloroiodomethane.
The systematic name for gypsum is calcium sulfate dihydrate.
PH3 is an acid.It is a flammable substance.
The systematic name of "cuclo" is not provided. If you provide the complete molecular structure, I can help you determine the systematic name of the compound.
The systematic name of barium chloride is barium dichloride.
