</span>The concentrations<span> of reactants and products in an equilibrium mixture are determined by </span><span>the </span>equilibrium constant K<span>.
</span>When writing chemical equations for reversible reactions, two arrows are used, for example: NH₄Cl(s) ⇆ NH₃(g) + HCl(g) or
CuSO₄(s) + 5H₂O(l) ⇆ CuSO₄·5H₂<span>O(s).</span>
The acid/base pair that give equivalence point that Cannot be predicted by general knowledge is NaOH and HCI ONH.
<h3>What is an Acid and base?</h3>
An Acid is a substances that is corrosive in nature and turn blue lithmus paper to red which it react with base to produce salt and water.
Acid dissolve metals.
Base is a substance that turn red lihthmus paper to blue and react with acid to produce salt and water.
Therefore, The acid/base pair that give equivalence point that Cannot be predicted by general knowledge is NaOH and HCI ONH.

Answer:
D. Its temperature will remain 100 C until all the vapours condenses
Explanation:
Heat absorbed by a substance to change the state of matter is known as latent heat. This heat is utilized to break the bonds between atoms of the substance so that they can undergo phase change.
So, when water boils at 100 degree Celsius then temperature will remain constant unless and until all the water changes into vapor. As it is the latent heat that breaks the bonds between hydrogen and oxygen atoms of water so that liquid state can change into gaseous state.
Since latent heat is a hidden heat, that is why, it does not get reflected and there is no change in temperature due to it.
Thus, we can conclude that it is true that temperature will remain at 100°C until all the vapor condenses for a sample of water vapor at 101°C as it cools.
Answer: -22.2 kJ
Explanation:
According to Hess’s law of constant heat summation, the heat absorbed or evolved in a given chemical equation is the same whether the process occurs in one step or several steps.

According to Hess’s law, the chemical equation can be treated as algebraic expressions and can be added or subtracted to yield the required equation. That means the enthalpy change of the overall reaction is the sum of the enthalpy changes of the intermediate reactions.

(2) 
(3) 
Reversing 1 ,2 and 3 and halving 1 and 2 and then adding we get net equation:
(4) 
Therefore, the heat of reaction, ΔH, for the reaction is -22.2 kJ
