<span>C) Sound is a mechanical wave and needs a medium to travel through while light is an electromagnetic wave.
There is no air for the sound waves to travel, therefore, no sound waves being transmitted. </span>
Answer:
The type of bond formed in FeS would be <u>Polar Covalent Bond</u>.
Explanation:
Types of Bonds can be predicted by calculating the difference in electronegativity.
If, Electronegativity difference is,
Less than 0.4 then it is Non Polar Covalent Bond
Between 0.4 and 1.7 then it is Polar Covalent Bond
Greater than 1.7 then it is Ionic Bond
For Fe and S,
E.N of Sulfur = 2.58
E.N of Iron = 1.83
________
E.N Difference 0.75 (Polar Covalent Bond)
Answer is: more H⁺ ions than OH⁻ ions.
<span>An Arrhenius acid is a
substance that dissociates in water to form hydrogen ions or
protons.
For example, hydrochloric acid dissociate in aqueous
solution to form hydrogen ions (H</span>⁺)
and chloride anion (Cl⁻):<span>
HCl(aq) → H</span>⁺(aq) + Cl⁻<span>(aq).
</span>
An Arrhenius base is a
substance that dissociates in water to form hydroxide ions (OH⁻<span>).
For example lithium hydroxide is an Arrhenius base:</span>
LiOH(aq) → Li⁺(aq) + OH⁻(aq).
