Number 9 is A and 10 is A
This reaction contains pure solids which are not considered when writing out equilibrium constant expressions.
O2...........SO2
I 2.9...........0
C -x.......... +x
E 2.9-x........ x
Q=0/2.9 = 0 ---->Q<K Reaction will go to the right
Since the coefficients are all 1, I won't bother putting in the exponents.
k=B/A
1.5= x / (2.9-x)
4.35 - 1.5x = x
2.5x = 4.35
x= 1.74
plug back in ice chart
2.9 - 1.74
=1.16
=1.2 ANSWER
Ca²⁺ion has a lower ratio of charge to volume.
The charge density of an ion is defined as the ratio of the charge of an ion to its volume. Scandium ion has high charge density than calcium ions. The charge density of an ion is defined as the ratio of the charge of an ion to its volume.
Charge density also depends on the size of the ion and valence electrons. The volume of an ion increases with its size. It is inversely proportional to ion volume and directly proportional to charge magnitude. Scandium and calcium are IV periodic elements with atomic numbers of 21 and 20 respectively. Scandium loses three electrons and has a +3 charge and calcium is a divalent cation. Hence, the Scandium ion has high charge density than the calcium ion.

Answer:
- c. <em>Aqueous solutions of hydrochloric acid and potassium hydroxide react to produce aqueous potassium chloride and water.</em>
Explanation:
The reaction is represented by the chemical equation
- HCl(aq) + KOH(aq) → KCl(aq) + H₂O(l)
The letters "aq" in parenthesis, next to the chemical formula of a compound, is used to indicate "aqueous" phase. It means that the compound is dissolved in water or, what is the same, it is an aqueous solution.
Hence, the choice C. is the best representation or description of the given reaction:
The <u>left side</u> or reactant side is:
HCl(aq) + KOH(aq)
↑ ↑ ↑
<em>aqueous solution of react aqueous solution of </em>
<em>hydrochloric acid with potassium hydroxide </em>
The <u>right side</u> or product side is:
KCl(aq) + H₂O(l)
↑ ↑ ↑
<em>aqueous and water</em>
<em>potassium chloride </em>
An isotope only differs in the number of neutrons it has. All isotopes of an element <span>have the </span>same<span> atomic number (the number of electrons/protons), therefore, they have the </span>same<span> number of electrons/protons and therefore similiar chemical properties.</span>
