At point C, the kinetic energy will be zero and the potential energy will be minimum. As the snowboarder moves from point C to B, there will be a transfer between the kinetic energy to the potential energy. At point B, the potential energy will be back to maximum.

Explanation:
Let us assume that the given data is as follows.
mass of barium acetate = 2.19 g
volume = 150 ml = 0.150 L (as 1 L = 1000 ml)
concentration of the aqueous solution = 0.10 M
Therefore, the reaction equation will be as follows.
Hence, moles of 
= 
.......... (1)
As, No. of moles = 
Hence, moles of 
will be calculated as follows.
No. of moles =
= 
(molar mass of is 255.415 g/mol)
= 
Moles of = 
= 0.01715 mol
Hence, final molarity will be as follows.
Molarity = 
= 
= 0.114 M
Thus, we can conclude that final molarity of barium cation in the solution is 0.114 M.
Answer:
The half-life varies depending on the isotope.
Half-lives range from fractions of a second to billions of years.
The half-life of a particular isotope is constant.
Compounds
Explanation:
Compounds are substances that can be broken down by chemical means. They are categorized as pure substances due to their definite composition.
- Compounds are substances composed of two or more kinds of atoms or elements joined together in a definite grouping.
- Properties of compounds differs from those of the constituent atoms.
- Compounds are broken down by chemical means because they are products of chemical changes.
- Several kinds of compounds exists through combinations of atoms.
- Compounds have definite compositions
