Answer : when a beaker of acid is titrated with a basic solution, the acid becomes neutralized.
Explanation :
The reaction in which an acid reacts with a base forming a salt and water is known as neutralization reaction.
During neutralization reaction, acid and base neutralize each other.
That means they both lose their properties and completely new substances are formed which have different properties
For example, a reaction of acid HCl with base NaOH produces water and salt, NaCl.
Therefore we can say that, when a beaker of acid is titrated with a basic solution, the acid is neutralized.
Answer:
ΔH = 1270kJ
Explanation:
Let's consider the following thermochemical equation.
B(s) + 3/2 O₂(g) → B₂O₃(s), ΔH = −1270kJ
Since ΔH < 0, this reaction is exothermic. According to the Lavoisier-Laplace law, if we reverse a reaction, its enthalpy will have the same value and opposite sign than the direct reaction.
B₂O₃(s) → B(s) + 3/2 O₂(g), ΔH = 1270kJ
For the inverse reaction, ΔH > 0, which means that it is endothermic.
