Please help: A 0.200 M NaOH solution was used to titrate a 18.25 mL HF

Chemistry
1 answer:
algol [13]3 years ago
7 0

The molar concentration of the original HF  solution : 0.342 M

Further explanation

Given

31.2 ml of 0.200 M NaOH

18.2 ml of HF

Required

The molar concentration of HF

Solution

Titration formula

M₁V₁n₁=M₂V₂n₂

n=acid/base valence (amount of H⁺/OH⁻, for NaOH and HF n =1)

Titrant = NaOH(1)

Titrate = HF(2)

Input the value :

\tt 0.2\times 31.2\times 1=M_2\times 18.25\times 1\\\\M_2=0.342

Give the clarification of heat and temperature on the basis of molecular motion?
sdas [7]

Explanation:

Heat is a form of thermal energy.

Heat is the sum of all the energy of the molecular motion in an object.

Temperature measures the average heat possessed by each molecule in a given substance.

 Molecules at a higher temperature possess more kinetic energy and they will move faster. This kinetic energy form is the heat variant of thermal energy.

Temperature is the measure of this heat energy of molecules.
