When 2.94 g of a metal combined with fluorine gas, 7.47 g of a metal fluoride formed. given this information, calculate the mass %f in the metal fluoride that formed.

 The mass % F  in  the metal fluoride that is formed is  60.64%

 calculation

Step 1:  calculate the mass  of fluorine (F)

mass  of F =  mass  of  metal fluoride  -  mass of the metal

     = 7.47 g - 2.94 g= 4.53 g

Step 2:  calculate  the  % mass of F

Mass % of  F =  mass  of F / mass  of metal  fluoride  x 100

mass % of F  is therefore  =  4.53  g/ 7.47  x 100 = 60.64%

the answer is: they rebelled against saddam hussein’s rule.

kurds opposed saddam rule and wanted independence. kurds in the north and shiites in the south revolt against hussein.

for example, the halabja attack in 1988 conducted against the kurdish people by the iraqi regime under saddam hussein, where between 4000 people are killed and around 9000 are injured.
