(D) lowers the enthalpy change in the overall reaction
A 12.5-g marble display 5.0 mL of water. The density is 2.5 g/ ml.
Density is defined as a measurement of how tightly packed the mass is within a substance or object. The concept of density is crucial because it enables us to predict which compounds will float and which ones will sink in a liquid. As a rule, objects float as long as their density is lower than the liquid they are placed in.
The density of a substance is determined by the mass, size, and arrangement of its atoms. Density is calculated by dividing a substance's mass by its volume.
Density = Mass / Volume
Given Mass = 12.5 g
Volume = 5.0 ml.
Density = 12.5 g / 5.0 ml
Density = 2.5 g / ml
Thus, a 12.5-g marble display 5.0 mL of water. The density is 2.5 g/ ml.

Hydroxide Ions
Acid and Bases are defined according to three different theories and concepts.
A) Arrhenius Concept
B) Lowry Bronsted Theory
C) Lewis Theory
According to Arrhenius Concept of Acid and Base, "Acid is any specie which when dissolved in water ionizes to produce H⁺ ions".
Examples:
HNO₃ → H⁺ + NO₃⁻
H₃PO₄ → 3 H⁺ + PO₄³⁻
While, "Bases are those species which when dissolved in water produces Hydroxyl Ions (OH⁻)".
Examples:
KOH → K⁺ + OH⁻
Ca(OH)₂ → Ca²⁺ + 2 OH⁻
When an Arrhenius base dissolves in water, it yields hydroxide ions (OH-).
When an Arrhenius base is dissolved in water, it yields hydroxide ions, which have a chemical formula of OH-. The formula for an Arrhenius base is usually represented as BOH, where B represents a cation (positive ion) and OH- represents the hydroxide ion. Some examples of Arrhenius bases include sodium hydroxide (NaOH) and potassium hydroxide (KOH).

Answer :AgOH is a solid.
Explanation;
AgOH can be produced from the reaction between NaOH(aq) and AgNO₃(aq). The balanced reaction equation is
NaOH(aq) + AgNO₃(aq) AgOH(s) + NaNO₃(aq)
AgOH is a brown color precipitate which has a Ksp value as 6.8 x 10⁻⁹. The molecular weight of AgOH is 124.88 g/mol.
Silver Hydroxide (AgOH) is generally a solid at room temperature, but its state can change under different conditions. It is not typically found in aqueous form.
In the field of Chemistry, AgOH, also known as Silver Hydroxide, is considered to be a solid at room temperature. Silver Hydroxide is an unstable compound that decomposes easily into its constituent water and silver oxide. Hence, it is not typically found in aqueous (dissolved in water) form. However, it's important to understand that its state can change under different conditions such as temperature and pressure.
