Compound is formed when two or more chemical elements are chemically bonded together. elements are made of atoms
Answer:
Titration
Explanation:
The best technique which can be used to determine the number of moles of the HCl in the sample is titration.
The given amount of HCl solution must be titrated with known concentration of the base like NaOH.
The volume of NaOH required must be noted also.
According to the reaction,

At equivalence point
Moles of
= Moles of 
Considering:-
Moles of 
Thus, in this way, moles of HCl can be determined.
<span>A neutralization reaction is a reaction in which an acid and a base react in an aqueous solution to produce a salt and water. An example of a neutralization reaction is the reaction of sodium hydroxide and hydrogen chloride to form sodium chloride and water. Answer is C.</span>
You need to first write a chemical equation and balance it
C₄H₁₀ + O₂ → CO₂ + H₂O
2 C₄H₁₀ + 13 O₂ → 8 CO₂ + 10 H₂O
1.0 moles X moles
1.0 mol C₄H₁₀ (

) = 4 moles of CO₂
