Answer:
Energy transformation is when energy changes from one form to another – like in a hydroelectric dam that transforms the kinetic energy of water into electrical energy. While energy can be transferred or transformed, the total amount of energy does not change – this is called energy conservation.

<u>Answer:</u> The bronsted acids for the given reaction are
<u>Explanation:</u>
According to the Bronsted-Lowry conjugate acid-base theory:
- An acid is defined as a substance which looses or donates protons and thus forming conjugate base.
- A base is defined as a substance which accepts protons and thus forming conjugate acid.
For the given chemical equation:
For the forward reaction, looses 1 proton to form and thus acts as bronsted acid.
For the backward reaction, looses 1 proton to form and thus acts as bronsted acid
Hence, the bronsted acids for the given reaction are
Answer: A. Metalloids exhibit properties of both metals and nonmetals
Explanation: Metalloids are elements that has a metallic appearance such as shiny, dull amd ductile but they possess the properties of nonmetals in which they are intermediately poor conductors of heat and electricity in which they are good semiconductors.
