Lowest. Highest
Answer:
% 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)
<em> mass = moles × molar mass</em>
mass = 1 mol × 59 g/mol
mass = 59 g
now we calculate the % weight of nickle in (Ni(SO₃NH₂)₂)
<em> % weight = (weight of element ÷ total weight) × 100</em>
% weight of nickle = (59 ÷ 250.87) × 100
% weight of nickle = 0.24 × 100
% weight of nickle = 24 %
Answer:
a)<em> Balanced equation:</em>
An equation is called balanced if there are same number and same type of atom on both sides of the equation.
b)<em>Reason:</em>
2KClO3--------2KCl + 3O2
Consider this equation in the reactants there are 2KClO3 and in the product there are 2KCl+3O2 . So reactants =products which is a case of balanced chemical equation .
