Potential energy is stored. As an item sits and does not move, potential energy builds up until said item moves, then it uses kinetic energy
Rocks are part of our planet. They tell stories like how they were formed and which environment they belong in. And it also tells us things about the past, because rocks came long before humans did.
Answer: B. Hydrolysis (adding water)
Explanation:
When peptide bonds join two or more amino acids together, this is refered to as a peptide. A polypeptide simply means several amino acids. We should also note that proteins contains polypeptides.
The reaction that is capable of breaking polypeptides into their component amino acids is hydrolysis. This simply means a chemical process whereby a water molecule is being added to a particular substance.
Answer:
stable, because there is always an equal amount of force surrounding the atom
Answer:
The correct option is: A. 0.168 M
Explanation:
Chemical reaction involved:
5 Fe²⁺ (aq) + MnO₄⁻ (aq) + 8 H⁺ (aq) → 5 Fe³⁺ (aq) + Mn²⁺ (aq) + 4 H₂O
Given: <u>For MnO₄⁻ solution</u>-
Number of moles: n₁ = 1, Volume: V₁ = 20.2 mL, Concentration: M₁ = 0.0250 M;
<u>For Fe²⁺ solution</u>:
Number of moles: n₂ = 5, Volume: V₂ = 15 mL, Concentration: M₂ = ?M
<u><em>To find out the concentration of Fe²⁺ solution (M₂), we use the equation:</em></u>
<u>Therefore, the concentration or molarity of Fe²⁺ solution: </u><u>M₂ = 0.168 M</u>
