Carbonic acid is a weak acid. Its weak ionization constant (Ka) is equal to:

Ka = [H⁺] [HCO₃⁻] / [H₂CO₃]

A weak acid is an acid that dissociates partially in the water.

The equation for the acid dissociation of carbonic acid is:

H₂CO₃ ⇄ H⁺ + HCO₃⁻

The weak ionization constant (Ka) is the equilibrium constant for this reaction, that is, the product of the concentration of the products divided by the product of the concentrations of the reactants, all of them raised to their stoichiometric coefficients.

Ka = [H⁺] [HCO₃⁻] / [H₂CO₃]

Carbonic acid is a weak acid. Its weak ionization constant (Ka) is equal to:

Ka = [H⁺] [HCO₃⁻] / [H₂CO₃]

Chromium;

[Ar]4s1 3d5

Strontium;

[Kr]5s2

Phosphorus;

[Ne]3s2 3p3

6p- n=6, l= 1, ml= 1, ms= 1/2

3d- n=3, l=2, ml=2,ms=1/2

GuDViN [60]

Answer:

The density of the stone whose mass is 25 g and its volume is 5 mL is 5 g/mL.

We have a graduated cylinder holding a volume of water equal to 2 mL. After a stone is added, the height of the water rose to 7 mL. The volume of the stone is equal to the difference in the levels of water.

The stone has a volume of 5 mL and a mass of 25 g. Its density, that is the ratio of the mass to the volume, is:

The density of the stone whose mass is 25 g and its volume is 5 mL is 5 g/mL.The density of the stone is 5 g/cm³.

Mass = 25 g

Volume = 7 mL – 2 mL = 5 mL = 5 cm³

Density = mass/volume = 25 g/5 cm³ = 5 g/cm³
