Answer:
Explanation:
a) Hydronium ion (H₃O⁺) is the acidic ion, after reacting with a base Calcium hydroxide the pH decreased. The base contained a hydroxide ion (OH⁻) which reacted with the Hydronium ion causing the decrease of hydronium ion.
b) The base which is Calcium hydroxide is made up of Calcium ion (Ca²⁺) and hydroxide ion (OH⁻) which reacts to form Calcium hydroxide [Ca(OH)₂]
Ca²⁺ + OH⁻ ⇒ Ca(OH)₂
a. The reason of ion that resulted into the decrease of the hydronium ion should be explained below.
b. The formula is Ca²⁺ + OH⁻ ⇒ Ca(OH)₂.
What is Hydronium ion?a) Hydronium ion (H₃O⁺) represent the acidic ion that should be reacted along with the base i.e. Calcium hydroxide when there should be decrease in the pH. Here the base should comprise of the hydroxide ion (OH⁻) that should be reacted with the Hydronium ion.
b. The formula should be
we know that
The base should be based on Calcium hydroxide comprise of Calcium ion (Ca²⁺) and hydroxide ion (OH⁻)
So, it should be like
Ca²⁺ + OH⁻ ⇒ Ca(OH)₂

What is the molecular formula for Tricarbon nonachloride?
A. CCl
B. C4Cl8
C. C3Cl9
D. T3N9
Answer:
C: C3CI9
Explanation:
Binary Molecular compound states that the molecular formula for tricarbon nonacholride is C3CI9
Hope this helps
Answer:
C
Explanation:
Think about the prefixes to solve this. I've attached a Latin prefix chart. It might help to memorize this!
Tri- carbon means 3 carbons.
Nona- chloride means 9 chlorines.
So the answer is C₃Cl₉.
The reason we use these prefixes is because it's a covalent compound. If it's ionic, we don't need to use the tri- or nona- parts of it.
