Answer:
C. Degree of ionization
Explanation:
The strength of an acid or a base is determined by how many H+/H3O+ or OH- ions are dissociated in solution. Therefore, it's describing the degree of ionization.
Example: HCl is a strong acid because in water it will pretty much 100% dissociate into H+ and Cl- ions.
Answer:
Atomic size decreases from left to right in the Periodic Table.
Explanation:
s you move from left to right, the nucleus gains protons.
This increases the positive charge of the nucleus and its attractive force on the electrons.
At the same time, electrons are added to the atoms as you move from left to right across a period.
These electrons reside in the same energy shell and do not offer complete shielding.
The effect of the increasing proton number is greater than that of the increasing electron number.
As a result, the valence electrons are held closer to the nucleus, and the atomic radius decreases.
Answer:
3S₈ + 28Br₂ => 8S₃Br₇
Explanation:
Start with either sulfur (S) or bromine (Br) and balance ...
3S₈ + Br₂ => 8S₃Br₇ or S₈ + 7/2Br₂ => S₃Br₇
Balance the remaining reactant ...
3S₈ + 56/2Br₂ => 8S₃Br₇
Remove fractions by multiplying by the fraction's denominator
2(3S₈ + 56/2Br₂ => 8S₃Br₇) => 6S₈ + 56Br₂ => 16S₃Br₇
Reduce to smallest whole number ratio => standard equation at STP ...
3S₈ + 28Br₂ => 8S₃Br₇
Answer and Explanation:
Your answer is...
The stars appear to move together along a path because of Earth's rotation on its axis.
The answer is erosion is the process of removing material
