PH is calculated using <span>Handerson- Hasselbalch equation,
pH = pKa + log [conjugate base] / [acid]
Conjugate Base = Acetate (CH</span>₃COO⁻)
Acid = Acetic acid (CH₃COOH)
So,
pH = pKa + log [acetate] / [acetic acid]
We are having conc. of acid and acetate but missing with pKa,
pKa is calculated as,
pKa = -log Ka
Putting value of Ka,
pKa = -log 1.76 × 10⁻⁵
pKa = 4.75
Now,
Putting all values in eq. 1,
pH = 4.75 + log [0.172] / [0.818]
pH = 4.072
11.2L/22.4L (STP value) x 1 mol of CH4 x 16.04 g of CH4 = 8.2 g
It can be made true by changing "cannot" to "can".
Answer:
The
of the given reaction is -129.6 kJ
Explanation:
The given chemical reaction is as follows.
Enthalpy of each reactant and products are as follows.
In the given chemical reaction involved two C-H bonds in the reactant side and one C-C bond in the product side therefore, the enthalpy of formation will be the negative.
Therefore, The of the given reaction is -129.6 kJ
Answer: intermolecular forces are described as forces that either cause attraction or repulsion between neighbouring particles or molecules
Explanation: liquids with strong intermolecular forces has the following properties:
1.) High boiling point
2.) high surface tension
3.) Low viscosity
4.) Low vapour pressure
While liquids with weak intermolecular forces has the following properties:
1.) Low boiling point
2.)low surface tension
3.) High viscosity
4.) High vapour pressure.
