Zamiast małej litery c, jako symbolu stężenia molowego, stosuje się czasem wzór cząstki w nawiasach kwadratowych, np. [NH 4 NO 3] = 0,5 mol/dm³, co oznacza roztwór azotanu amonu o podanym stężeniu.
30 paź 2024 · Nasz kalkulator molarności jest narzędziem do przeliczania stężenia masowego dowolnego roztworu na stężenie molowe (lub przeliczania gramów/ml na mole). Przy jego użyciu możesz również obliczyć masę substancji potrzebną do osiągnięcia pożądanej molarności.
23 cze 2023 · According to Le Chatelier's principle, if pressure is increased, then the equilibrium shifts to the side with the fewer number of moles of gas. This particular reaction shows a total of 4 mol of gas as reactants and 2 mol of gas as products, so the reaction shifts toward the products side.

c Example 1: CO (g) + 3 H 2 (g) ¾¾fi ‹¾¾ CH 4 (g) + H 2 O (g) When 1.00 mol CO and 3.00 mol H 2 are placed in a 10.0 L vessel at 927 ° C and allowed to come to equilibrium, the mixture is found to contain 0.387 mol H 2 O. Calculate the equilibrium constant for this reaction.
Calculate \(ΔG\) for the reaction of nitric oxide with oxygen to give nitrogen dioxide under these conditions: T = 50°C, P NO = 0.0100 atm, \(P_{\ce{O_2}}\) = 0.200 atm, and \(P_{\ce{NO_2}} = 1.00 × 10^{−4} atm\). The value of \(ΔG^o\) for this reaction is −72.5 kJ/mol of O 2. Are products or reactants favored? Answer
18 maj 2021 · In this work, a secondary-N-doping strategy is developed for enhancing the ORR electrocatalytic performance of Co(OH) 2 /NC, where NC is prepared from pyrolysis of carbon with melamine at 900 °C, then Co(OH) 2 /NC is obtained from depositing Co(OH) 2 nanosheets on NC.
