RCHO+ 2[Ag(NH3)2]OH = RCOOH + 2Ag + 4NH3 + H2O For every molecule of aldehyde, 2 ions of Ag+ are used, thus n(A)/n(Ag+)=1/2 and n(B)/n(Ag+)=1/2 Now if the amount of Ag+ ions is the sum of the ions that reacted with A and the ions that reacted with B n(...
How to calculate enthalpy of combustion Standard Enthalpy of Combustion: Standard enthalpy of combustion, {eq}\Delta H_c^{\theta} {/eq} is the enthalpy change when one mole of substance is burnt in plentiful oxygen under standard temperature and pressure. Answer and Explanation: 1 Become a...
