As temperature increases, pressure increases as well. ... As temperature increases, the molecules move faster, increasing the number of collisions and the force of collisions between the molecules and the walls of the container. This increases the pressure on the walls of the container.
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:
Radium
Explanation:
It has the highest atomic number so it would have more shells, making it larger than the others.
