8. what is the % weight of nickel in nickel sulfamate (ni(so3nh2)2) ?

% weight of nickle = 24 %

Explanation:

molar mass of Nickel Sulfamate (Ni(SO₃NH₂)₂) = 250.87 g/mol

Solution

1st we write down the molar mass of Ni

molar mass of Ni = 59 g/mol

now we write down the number of moles of Ni in (Ni(SO₃NH₂)₂)

number of moles of Ni = 1 mol

Now we calculate the mass of nickle present in (Ni(SO₃NH₂)₂)

        mass = moles × molar mass

mass = 1 mol × 59 g/mol

mass = 59 g

now we calculate the % weight of nickle in (Ni(SO₃NH₂)₂)

      % weight = (weight of element ÷ total weight) × 100

% weight of nickle = (59 ÷ 250.87) × 100

% weight of nickle = 0.24 × 100

% weight of nickle = 24 %

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.
