Answer:

The answer to your question is: 1 J = 10, 000, 000 ergs

Explanation:

(1 kgm²/s²)(1000 g/ 1 kg) = 1000 gm²/s²

(1000 gm²/s²)(100 cm/1 m) = 1 00 000 gmcm/s²

1 00 000 gmcm/s² (100 cm / 1m) = 10 000 000 gcm²/s²

                                                       = 10 000 000 ergs

A buffer is prepared by adding 12.0g of ammonium chloride (NH4Cl) to 250mL of 1.00 M NH3 solution?The pH is 9.3 Write the net io
solniwko [45]

Answer:- NH_3(aq)+H^+(aq)\rightleftharpoons NH_4^+(aq)

Explanations:- The solution we have is a buffer solution and we know that a buffer solution resists a change in its pH if a strong acid or base is added to it.

Here, the buffer solution we have is of a weak base and it's conjugate acid. So, a strong acid(nitric acid) is added to this buffer then it reacts with the base present in the buffer so that the acid could be neutralized. This is called buffer action.

The net ionic equation is written as:

NH_3(aq)+H^+(aq)\rightleftharpoons NH_4^+(aq)

Note that HNO_3 is a strong acid and nitrate ion is the spectator ion so it is not included in the net ionic equation.
