Achemist finds that 30.82g of nitrogen will react with 17.60g , 35.20g, or 88.00g of oxygen to form four different compounds. calculate the mass of oxygen per gram of nitrogen for each compound.

17.60 g / 30.82 = 0.57  

35.20g / 30.82 = 1.14 (twice as much oxygen as the first)  

70.40 / 30.82 = 2.28 (4 X's as much oxygen as the first)  

88.00 / 30.82 = 2.85 (5 X's as much oxygen as the first)  

"the law of multiple proportions to the idea that chemical combination consists in the interaction of atoms of definite and characteristic weight"

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.
