What Is the difference between organic and inorganic matter?
Charra [1.4K]
Organic compounds are compounds that contain carbon atoms.

Organic matter is any waste product that occurs naturally (i.e. snake skin, feces, and other traces of life).

Inorganic matter would lack carbon compounds. Radioactive waste at nuclear power plants is inorganic.

how many moles of sodium hydroxide would have to be added to 250 ml of a 0.403 m acetic acid solution, in order to prepare a buf
jonny [76]

The volume of the buffer solution having a ph value is calculated by henderson's hasselbalch equation.

Buffer solution is water based solution which consists of a mixture containing a weak acid and a conjugate base of the weak acid. or a weak base and conjugate acid of a weak base.it is a mixture of weak acid and a base. The pH of the buffer solution is determined by the expression of the henderson hasselbalch equation.

              pH=pKa + log [salt]/[acid]

Where, pKa =dissociation constant , A- = concentration of the conjugate base, [HA]= concentration of the acid. Here, a buffer solution contains 0.403m acetic acid  and 250 ml is added  in order to prepare a buffer with a ph of 4.750. Putting all the values in the henderson hasselbalch equation we find the pH of the buffer solution.

One success of Johann Döbereiner's law of triads was that it organized most of the known elements into three-element groups base
jenyasd209 [6]
That statement is true

it was easy to organize 'all' the elements in a group of threes because back then they only knew about 15 - 20 elements

hope this helps
