First, we determine the mass of stearic acid in the solution by multiplying the given concentration by the volume.
mass of stearic acid = (5.4 x 10^-4 g/L) (0.25 mL) (1000 mL/1L)
= 0.135 g
Then, we divide this amount by the molar mass in order to obtain the number of moles of stearic acid. The molar mass of stearic acid is 284.4772 g/mol.
moles stearic acid = 0.135 g / (284.4772 g/mol)
= <em>4.75 x 10^-4 mol</em>
The chemical reaction between the reactants:
3 AgNO₃ (aq) + FeCl₃ (aq) → 3 AgCl (s) + Fe(NO₃)₃ (aq)
Explanation:
We have the following chemical reaction:
3 AgNO₃ (aq) + FeCl₃ (aq) → 3 AgCl (s) + Fe(NO₃)₃ (aq)
Complete ionic equation:
3 Ag⁺ (aq) + 3 NO₃⁻ (aq) + Fe³⁺ (aq) + 3 Cl⁻ (aq) → 3 AgCl (s) + Fe³⁺ (aq) + 3 NO₃⁻ (aq)
We remove the spectator ions and we get the net ionic equation:
Ag⁺ (aq) + Cl⁻ (aq) → AgCl (s)
where:
(aq) - aqueous
(s) - solid

Answer:
The dissociation of copper sulfate into ions is an exothermic chemical reaction that releases heat into the surroundings.
Explanation:
Some of the potential energy stored in the solid sample of anhydrous copper sulfate is released as heat as the sample dissolves and dissociates into ions in the water. This is due to the large lattice energy of the crystalline copper sulfate.

The lower you go, the more acidic. The higher you go, the more alkaline. Your answer would most likely be 6.
Answer:
A
Explanation:
The answer is A) because the A container has tightly packed molecules but not as tight as C so that means A is liquid, and C is a solid which makes B a gas
