Igneous <span>rock ! Of course oh how i miss middle school.........</span>
I'll just list down the acidic, basic, and neutral salts.
ACIDIC
<span>THE CATION: is the conjugate acid of a weak base
THE ANION: Conjugate Base of A Strong Acid
</span>Ammonium Sulfate - <span>(NH₄)₂SO₄
</span>Ammonium Chloride - NH₄Cl
BASIC
<span>THE CATION: comes from the cation of a strong Base (i.e. Na+, K+, Li+)
The Anion: comes from the conjugate base of a weak acid
</span>Sodium Acetate - CH₃COONaSodium Phosphate - <span>Na₃PO₄
</span>Calcium Acetate - (CH₃COO)₂Ca
NEUTRAL
<span>THE CATION: comes from a strong base
THE ANION: comes from a strong acid
</span>Sodium Nitrate - NaNO₃
Barium Chloride - BaCl₂Potassium Chloride - KCl
Answer:
1.45 mol
Explanation:
Given data
- Volume of the gas (V): 8.77 L
- Temperature of the gas (T): 20 °C
- Pressure of the gas (P): 3.98 atm
Step 1: Calculate the absolute temperature (Kelvin)
We will use the following expression.
Step 2: Calculate the number of moles (n) of the gaseous sample
We will use the ideal gas equation.
Answer:
The colour of the solution will change from blue to transparent and copper will be observed as a layer on the Aluminium piece.

Answer:
The volume of water added is 30 mL
Explanation:
Given data
- Initial concentration (C₁): 0.4 M
- Initial volume (V₁): 10 mL
- Final concentration (C₂): 0.1 M
We can find V₂ using the dilution rule.
C₁ × V₁ = C₂ × V₂
0.4 M × 10 mL = 0.1 M × V₂
V₂ = 40 mL
The volume of water added is
V₂ - V₁ = 40 mL - 10 mL = 30 mL
