Answer:
Your answer is B. Energy cannot be destroyed
Explanation:
The total amount of energy remains constant in an isolated system. It states that energy can neither be created nor destroyed, but it can change from one form to another.
B) you can make a diagnol DB and separate the parallelogram into triangle DBA and triangle DBC.
The area of each of the triangle would be
1/2 * 8 *3/4 =
1/2 * 2 *3 =
3 feet or foot ^2
Change in the amount of volume left inside the basketball for the remaining air coming in
Answer:
The answer is in the explanation.
Explanation:
A titration of H₂X with KOH produce:
H₂X + 2KOH → 2H₂O + K₂X
It is possible to obtain the moles of H₂X because the moles of KOH are the spent volume of the titration in liters × 0,455M. As for a complete titration of H₂X moles you need twice moles of KOH you know the moles of KOH obtained are half H₂X moles.
As you know the mass of the solid acid that you titrate and molar mass of acid is:
mass of acid / moles of acid. You can determine the molar mass of the unknown acid.
