Answer:
Option a,
Explanation:
According to Arrhenius concept of acids and bases, acids are those substances which releases H+ in aqueous solution and bases are those which releases OH- in aqueous solution.
Among the given only can release in aqueous solution.
LiOH releases , therefore it is an Arrhenius base.
and cannot releases .
So, the correct option is option a.
C a scientist because they would be the ones who are most qualified to do the experiment and get accurate results
Answer:
Option D: Fluorine
Explanation:
From the periodic table, Nickel and Sodium are metals. Which means that they are good conductors of electricity.
While silicon is a metalloid. A metalloid has properties of both metals and nonmetals. Thus, it has tendencies to conduct electricity.
Fluorine is a non - metal which means that it doesn't conduct electricity.
Thus, the most likely that is not a good conductor is Fluorine.
Answer:
Very Likely B.
Explanation:
Increasing temperature inside a closed container - keeping everything constant will make pressure increase. Because the energy being held by the molecular (the gas molecules) rises, the container may expand meaning the volume increases.
Analytical
Analytical chemistry seeks to determine the composition of substances.
