Answer : The mass of Ni is, 80.346 g
Solution :
First we have to calculate the number of moles.
Now we have to calculate the number of atoms of 
As 1 moles contains 
number of molecules
So, 1.369 moles contains 
number of molecules
One molecule has one nitrogen atom then number of molecules of will contain number of nitrogen atoms
As per question number of Ni atoms is equal to the number of nitrogen atoms
Number of Ni atoms= atoms
Number of moles = 
Mass of Nickel = 
Molecular mass of Nickel = 58.69 g/mol
Mass of nickel = 
Chemical reactions happen when two or more atoms go together to form molecules or when Atoms brake
Answer:
D) 1/2
Explanation:
Using Ideal gas equation for same mole of gas as
Given,
P₂ = 4P₁
T₂ = 2T₁
Using above equation as:
<u>The volume change by half of the original.</u>
