is a polyprotic acid. Write balanced chemical equations for the sequence of reactions that carbonic acid can undergo when it's d

Burka [1]

Answer:

H₂CO₃ H₂O ⇄ HCO₃⁻ + H₃O⁺ Ka1

HCO₃⁻ + H₂O ⇄ CO₃⁻² + H₃O⁺ Ka2

CO₃⁻² + H₂O ⇄ HCO₃⁻ + OH⁻ Kb1

HCO₃⁻ + H₂O ⇄ H₂CO₃ + OH⁻ Kb2

Explanation:

Formula for carbonic acid is: H₂CO₃

It is a dyprotic acid, because it can release two protons. We can also mention that is a weak one. The equilibrums are:

H₂CO₃ H₂O ⇄ HCO₃⁻ + H₃O⁺ Ka1

HCO₃⁻ + H₂O ⇄ CO₃⁻² + H₃O⁺ Ka2

When the conjugate strong bases, carbonate and bicarbonate take a proton from water, the reactions are:

CO₃⁻² + H₂O ⇄ HCO₃⁻ + OH⁻ Kb1

HCO₃⁻ + H₂O ⇄ H₂CO₃ + OH⁻ Kb2

Notice, that bicarbonate anion can release or take a proton to/from water. This is called amphoteric,

What would cause the equilibrium to shift left in this reaction? CO + 3H2 ? CH4 + H2O A. Adding heat to the product mixture B. A

Irina-Kira [14]

Answer:

Pretty sure the answer is A on Plato

Explanation:

I looked it up, and it said that raising the temperature would cause the equilibrium to shift left.

1 Clouds are formed when millions of drops of water become suspended in the air. Which

ioda

Answer:

C Condensation of water vapor

Explanation:

One of the components of the atmosphere is water vapour. Water vapour is always present in air.

This water vapour may combine with particles of dust and smoke and condense around them to form clouds.

As more water vapour condenses and coalesces, the clouds become thicker and precipitation eventually follows.

Classify each of the following as an exothermic or endothermic reaction:

serious [3.7K]

<h3><u>Answer;</u></h3>

1) 2H2(g)+O2(g)⟶Δ2H2O(g)+483.6kJ - Exothermic

2) 6CO2(g)+6H2O(l)+15000kJ⟶C6H12O6(aq)+6O2(g) - Exothermic

3) 2Al(s)+Fe2O3(s)⟶Al2O3(s)+2Fe(s)+850kJ - Exothermic

<h3><u>Explanation</u>;</h3>

Exothermic Reaction is a chemical reaction in which heat is given out is known as exothermic reaction, while, and endothermic Reaction is a chemical reaction in which heat energy is absorbed is known as endothermic reaction.
The reaction between carbon dioxide and water is an example of an exothermic reaction. When most gases dissolve in solution, the process is exothermic meaning that heat is released as the gas dissolves
The reduction of ferric oxide by aluminium is highly exothermic and therefore the iron formed will be in the molten state.
