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:
The critical chemical difference is that CO2 contains one atom of carbon and two atoms of oxygen, whilst CO has one carbon and one oxygen atom.
The statement a) it orbits around the nucleus of an atom. does not describe a proton.
- Protons is known as nucleon and Is found in the nucleus. It doesn't revolve around nucleus of atom.In circular orbits, electrons move around the nucleus.
- In his well-known gold foil experiment from 1911, Ernest Rutherford made the discovery of the atom's nucleus.
- He came to the conclusion that the majority of an atom's volume was empty and that all of the positively charged particles in it were concentrated in a single core.
- The mass of a proton is around 1835 times that of an electron.
- The atomic number is the quantity of protons in an element's nucleus.
- The mass of a proton is 1.6726219 × 10^-27 kilograms.
Proton is embedded inside the nucleus of atom along with neutron and electron revolve around the nucleus in fixed orbit.

The answer is System.
When a scientific investigation is in progress, its used to perform and understand the natural phenomenon that goes on using the scientific method. Since this is a descriptive investigation, it provides a descriptive account of any system by looking at it without any prior knowledge to that subject. This method of investigation does not use a hypothesis. Thus, proves our answer correct.
Best of Luck!
