Explanation:
When the balloon is placed above the beaker as described and heating commences, the balloon inflates more. This increased inflation is due to the expansion of the gas in the balloon.
The gas expands because the molecules of gas inside the balloon receive a greater kinetic energy when the temperature was increased hence they move faster and spread out. Recall that temperature is defined as a measure of the average kinetic energy of the molecules in a body.
As the gas in the balloon is heated up, its density decreases. The more the beaker is heated the more the balloon becomes inflated.
When the balloon is removed from the beaker and placed in an ice bath, the balloon shrinks as temperature decreases. This is in conformity with Charles's law.
Answer:
0.067 M
Explanation:
Given data:
Volume of solution = 1.00 L
Mass of BaCl₂ = 14 g
Molarity of solution = ?
Solution:
Molarity is used to describe the concentration of solution. It tells how many moles are dissolve in per litter of solution.
Formula:
Molarity = number of moles of solute / L of solution
Now we will calculate the number of moles first.
Number of moles = mass/ molar mass
Number of moles = 14 g/ 208.23 g/mol
Number of moles = 0.067 mol
Now we will calculate the molarity.
Molarity = 0.067 mol / 1.00 L
Molarity = 0.067 M ( mol/L=M)
Answer:
Dissociation, dispersion, and ionization.
Answer:
Explanation:
Chlorine is the element of group 17 and third period. The atomic number of chlorine is 17 and the symbol of the element is Cl.
The electronic configuration of the element chlorine is:-
Chloride ion is formed when chlorine atom gain one more electron. So, the ground-state electron configuration for the chloride ion is:-
