Answer:
1813.74g
Explanation:
Given parameters:
Number of moles of radon = 8.17moles
Unknown:
Mass of radon = ?
Solution:
To solve this problem, we use the expression below:
Number of moles =
Molar mass of radon = 222g/mol
Now insert the parameters and solve;
Mass of radon = Number of moles x molar mass
= 8.17 x 222
= 1813.74g
Answer:
Explanation:
The balanced chemical reaction equation is;
2AgNO3(aq) + Cu(s) -> 2Ag(s) + Cu(NO3)2(aq)
When we balance chemical reaction equations, we ensure that the number of atoms of each element on the left hand side of the reaction equation is exactly the same number of atoms of each element on the right hand side of the reaction equation.
Let us consider this reaction;
There are two atoms of Ag on both sides of the reaction equation
There are six atoms of O on both sides of the reaction equation
There are 2 atoms of N on both sides of the reaction equation
There is one atom of Cu on both sides of the reaction equation.
Hence, the reaction equation is balanced.
