The steps usually involves adding the known solution (the titrant) to a known quantity of the unknown solution (the analyte) until the reaction is complete which can be understood in detail as below with the help of through out process of titration.
<h3 /><h3>What is Titration ?</h3>
A titration is a technique used to work out the concentration of an unknown solution based on its chemical reaction with a solution of known concentration.
Steps in order to determine the concenteration of base solution ;
(Acid-Base Titration)
- Choose the titrant.
- Choose the titrate.
- Select the normality of the titrate.
- Choose the volume of the liquid to be pipetted out.
- Select the indicator.
- Start titration.
- End point is noted at the colour change of the solution.
- From the final reading the normality of titrant can be calculated by the equation:
N₁V₁=N₂V₂
- After finding the normality, the amount of given substance in the whole of the given solution can be calculated by the equation:
Mass = Equivalent weight x Normality \ Volume {1000}

The enthalpy of the reaction can be obtained from the enthalpies of formation as -16.2 kJ/mol.
<h3>What is the enthalpy of reaction?</h3>
We know that any time that there is a chemical reaction, there is an interaction that place between the reactants and the products and as such we are going to get new substances and these are the substances that I have referred to here as the products of the reaction.
In this case, we are asked to obtain the enthalpy change of the reaction. This tells us the heat that could have been absorbed or evolved in the reaction. We have to at this point know that the enthalpy change of the reaction gotten from;
Sum of enthalpy of the products - Sum of enthalpy of the reactants
ΔH = [(-484.5)] - [(-393.5) + (-74.8)]
ΔH = (-484.5) + 468.3
ΔH = -16.2 kJ/mol

It suggests that life changes over time by showing different animals at different stages in their life, also giving more than one example on how they can change during early development and throughout their lives
Answer:
Weight of boulder = 22,400 gram
Explanation:
Given:
Volume = 8,000 cm³
Density = 2.8
Find:
Weight of boulder
Computation:
Weight of boulder = Volume x Density
Weight of boulder = 8,000 x 2.8
Weight of boulder = 22,400 gram
