Hearing loss due to sound energy damaging the nerve cells in the inner ear. Many animals behavior is influenced by sound energy. They learn to associate events with sounds, so they run when something crunches in the dry grass (might be a coyote), but won't be bothered by the sound of a waterfall. Mood is affected by sound energy. A wine glass can break with sound energy, if the frequency matches the resonant frequency of the wine glass and the amplitude is great enough (one Mythbusters show featured a professional singer who broke a wine glass with his voice without any amplification).
Answer:
A conductor is a material that permits electrons to effortlessly go through it. Copper is a good conductor. Note that the valence shell has just a single electron.
While;
Materials that don't conduct are named insulators.(i.e. glass, porcelain, plastic, elastic. The covering on electrical wire is an insulator.)
Insulators don't conduct since they have a full or almost full valence shell and along these lines their electrons are firmly bound.
Explanation:
According to Bohr Rutherford model of Atom, An Atom contains three essential particles; Protons and neutrons that make up the nucleus and the electrons that circle or orbit the nucleus. The electrons circle the nucleus.

Answer:
2.67g Ni
Explanation:
To convert from moles to mass, use molar mass as a conversion factor.
Nickel has a molar mass of 58.69g/mol.
0.0455mol (
) = 2.67g Ni
<h3><u>Answer;</u></h3>
CaCO3(s)+ 2 H+(aq) → Ca+2 + CO2(g) + H2O(l)
<h3><u>Explanation</u>;</h3>
- The reaction of an acid with calcium carbonate is an example of an acid-base reaction.
- In these reactions, an acid will react with a base to form a salt and water. The acid was neutralized by the base.
- For example, CaCo3 will neutralize HCl by the following equation:
<em>2HCl(aq) +CaCO3(s) → CaCl2(aq) + H2O(l) + CO2(g)</em>
