SiBr3 The molecular formula is Si2Br6
Dibromine Trinitride
Very probable Mg4Si4 doesn't exist; magnesium silicide is Mg2Si.
Magnesium oxide is not a dangerous product! Items that are easy to burn, explode, and strongly corrosive are dangerous goods! ! !
Do you mean Co2S3? If so, that's cobalt (III) sulide. You have to be careful in chemistry in distinguising between upper and lower case letters. CO is carbon monoxide, a compound of the two elements carbon and oxygen. Co is the element cobalt, a metal, Much less likely is CO2S3 which is a complex of carbon disulfide/sulfur dioxide, better written as CS2.SO2.
A formula unit is an empirical formula.
Formula: Br2O3
Br2O7
Dibromine Trinitride
NaSi
The formula is Ba2Si. The name of this compound is barium silicide.
B2Si----> Diboron Silicide
Dibromine monoxide would have the formula of Br2O.
Diboride Silicon I'm pretty sure it's Diboron monosilicide...
B6Si
hexaboron silicide
zinc silicide
hexaboron silicide
