Determine the volume in mL of 0.242 M NaOH(aq) needed to reach the equivalence (stoichiometric) point in the titration of 46.79
Alla [95]

The volume (in mL) of 0.242 M NaOH solution needed for the titration reaction is 39.44 mL

<h3>Balanced equation </h3>

CH₃CH₂COOH + NaOH —> CH₃CH₂COONa + H₂O

From the balanced equation above,

  • The mole ratio of the acid, CH₃CH₂COOH (nA) = 1
  • The mole ratio of the base, NaOH (nB) = 1

<h3>How to determine the volume of NaOH</h3>
  • Volume of acid, CH₃CH₂COOH (Va) = 46.79 mL
  • Molarity of acid, CH₃CH₂COOH (Ma) = 0.204 M
  • Molarity of base, NaOH (Mb) = 0.242 M
  • Volume of base, KOH (Vb) =?

MaVa / MbVb = nA / nB

(0.204 × 46.79) / (0.242 × Vb) = 1

Cross multiply

0.242 × Vb = 0.204 × 46.79

Divide both side by 0.242

Vb = (0.204 × 46.79) / 0.242

Vb = 39.44 mL

Thus, the volume of NaOH needed for the reaction is 39.44 mL

Atoms are composed of a central nucleus which is surrounded by orbiting
ad-work [718]

Answer:

            Atoms are composed of a central nucleus which is surrounded by orbiting <u>Electrons</u>.

Explanation:

                   The word Atom is derived from atomos meaning indivisible particle. An atom is a very small sized particle and its size is approximately 100 picometers.

                    Atoms are composed of a Nucleus which contains protons and neutrons and the nucleus is surrounded by orbiting electrons. Also, the nucleus is positively charged due to +ve protons and the electrons revolving around nucleus are -vely charged making overall atom neutral in nature.

                   Atoms react with another atoms due to the presence of valence electrons present in the valence shell of an atom. The valence electrons would make a covalent bond by mutually sharing the electrons or it may form an ionic bond by gaining and loosing valence electron.
