Answer:
The reaction is:
H⁺
CaCO₃ ⇄ Ca²⁺ + CO₃ ⇄ HCO₃
The standard free energy change is ΔG = ΔH - TΔS
Explanation:
Limestone is a mineral familiar with calcium carbonate, and being very common, the acid present in acid rain dissolves it reacting with carbonate, since the acids present in acid rain are characterized by being highly soluble in water and are also strong acids. The reaction is as follows:
H⁺
CaCO₃ ⇄ Ca²⁺ + CO₃ ⇄ HCO₃
The spontaneity of the reaction is equal to:
ΔG = ΔH - TΔS
The sign of the standard free energy changes from positive to negative.
The volume (in dL) of the piece of iron having a mass of 3.92 kg is 4.99 dL
<h3>What is density? </h3>
The density of a substance is simply defined as the mass of the subtance per unit volume of the substance. Mathematically, it can be expressed as
Density = mass / volume
<h3>How to determine the volume of the iron</h3>
From the question given above, the following data were obtained:
- Mass of iron = 3.92 kg = 3.92 × 1000 = 3920 g
- Density of iron = 7.86 g/cm³
- Volume of iron =?
Density = mass / volume
Thus,
Volume = mass / density
Volume of iron = 3920 / 7.86
Volume of iron = 498.7277 cm³
Divide by 100 to express in dL
Volume of iron = 498.7277 / 100
Volume of iron = 4.99 dL
Thus, the volume of the iron is 4.99 dL

=22.78 g
Answer:
c iodine
Explanation:
fluorine is a halogen group element like Bromine, Iodine,Astatine,Chloride
I do not know if this is the correct answer,
Ionic Bonds - Whichever two atoms give one electron to the other
Covalent Bond - Is whenever two atoms share electrons and they go back and forth between the two
I do not know what the third type is you would have to comment and let me know and I will try to find it for you! :)
