1. Potential Energy is stored energy a object has when it's not moving.
2. Potential Energy is it's highest on the first stage because as you see the roller coaster is bout to go down the tract which is going to higher the kinetic energy and lower the potential energy.
3. Kinetic Energy is the amount of energy a object has when it's in motion or moving.
4. Kinetic Energy is it's highest in the third stage after it's gone down the tract and potential energy fully decreased and it's at zero.
Remember that potential energy is stored energy so when a object is not moving in this case the roller coaster isn't moving on the first stage when its bout to go down the roller coaster. Kinetic energy is the amount of energy a object has when it's in motion so in this case the third stage would have the highest example of Kinetic energy because it's fully in motion and has no potential energy.

Answer:
25.6mL NaOH
Explanation:
We are given the Molarity of the solution (
) and the volume of the solution (.02L).
By multiplying the two together, we can find the moles of solution that are reacted with HCl.
This gives us .0082 moles of HCl.
We then find the moles of NaOH that are needed to react with the HCl using the equation.
As HCl and NaCl have a 1:1 ratio, we need .0082 mol of NaOH.
Dividing this value by the Molarity of the solution
Gives us the answer, in Liters (.0256), which we can then divide by 100 convert to mL.
Answer:
H2SO4(aq) + Mg(OH)2(aq) -> MgSO4(aq) + 2H2O(l)
Explanation:
A neutralization reaction is a chemical reaction in which the acid, (aqeous H2SO4) reacts completely with an appropriate amount of base, (aqueous Mg(OH)2) to produce salt, (aqueous MgSO4) and water, (liquid 2H2O) only.
H2SO4(aq) + Mg(OH)2(aq) -> MgSO4(aq) + 2H2O(l)
Acid + base → Salt + Water.
During this reaction, the hydrogen ion, H+, from the H2SO4 is neutralized by the hydroxide ion, OH-, from the Mg(OH)2 to form the water molecule, H2O.
Thus, the formation of salt, MgSO4(aq) and water, 2H2O(l) makes it a neutralization reaction.
