NaH + H 2 O = Na {+} + OH {-} + H 2. Wyważanie krok po kroku metodą inspekcji. Zrównoważmy to równanie, stosując metodę inspekcji. Najpierw ustawiamy wszystkie współczynniki na 1: 1 NaH + 1 H 2 O = 1 NaOH + 1 H 2. Dla każdego elementu sprawdzamy, czy liczba atomów jest zrównoważona po obu stronach równania.
Przykłady: Fe, Au, Co, Br, C, O, N, F. Ładunki jonu nie są wspierane i będę ignorowane. Wymień grupy niezmienne w związkach chemicznych, aby uniknąć niejasności. Na przykład, C6H5C2H5 + O2 = C6H5OH + CO2 + H2O nie będzie bilansowane, ale XC2H5 + O2 = XOH + CO2 + H2O już tak.
21 gru 2023 · When the complex ion with EDTA is formed, the EDTA ligand displaces six aqua ligands at once. Ethylenediamine ligands displace two at a time and ammine ligands displace one at a time. Based on this we would expect [Ni(EDTA)]2 − to be the most stable and [Ni(NH 3) 6]2 + to be the least stable.
To balance a chemical equation, enter an equation of a chemical reaction and press the Balance button. The balanced equation will appear above. Use uppercase for the first character in the element and lowercase for the second character. Examples: Fe, Au, Co, Br, C, O, N, F.
23 cze 2023 · Solution. 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.
30 cze 2023 · Compare what happens if you replace two water molecules around a [Cu(H 2 O) 6] 2+ ion with either 2 ammonia molecules or one molecule of 1,2-diaminoethane. This second structure is known as a chelate from a Greek word meaning a crab's claw.
10 sie 2021 · Co(OH) 2 @NC polyhedron performs more excellent activity and durability compared with noble metal catalysts. In particular, Co(OH) 2 @NC presents excellent OER and ORR catalytic activity by virtue of its unique structure, high porosity and the synergistic catalysis between Co(OH) 2 and nitrogen-doped carbon.
