Najpierw ustawiamy wszystkie współczynniki na 1: 1 K 2 O + 1 H 2 O = 1 KOH. Dla każdego elementu sprawdzamy, czy liczba atomów jest zrównoważona po obu stronach równania. K nie jest zrównoważony: 2 atomów w odczynnikach i 1 atomów w produktach. Aby zrównoważyć K po obu stronach: Pomnóż współczynnik dla KOH przez 2. 1 K 2 O + 1 H 2 O = 2 KOH.
Thermodynamics of the reaction can be calculated using a lookup table. ΔS = S products - S reactants. If ΔS < 0, it is exoentropic. If ΔS > 0, it is endoentropic. ΣΔS° (products) > ΣΔS° (reactants), so KOH = K2O + H2O is endoentropic (increase in entropy). ΔG = G - G. If ΔG < 0, it is exergonic.
Step-by-Step Guide to Balance: K + H₂O = KOH + H₂1. Write down the unbalanced equation: K + H₂O = KOH + H₂2. List the number of atoms for each element on b...
H is balanced: 2 atoms in reagents and 2 atoms in products. O is balanced: 2 atoms in reagents and 2 atoms in products. All atoms are now balanced and the whole equation is fully balanced: K 2 O (s) + H 2 O (l) = 2 KOH (aq) Balancing step by step using the algebraic method.
13 lis 2015 · Provided that the given reactants and products are correct, the balanced equation is 2KO2 + 2H 2O → 2KOH + O2 + H 2O2. Explanation: First tally all the atoms involved in the reaction. You can do this by looking at the subscripts. KO2 + H 2O → KOH + O2 + H 2O2 (unbalanced) left side: K = 1. O = 2 + 1 (do not add this up yet) H = 2. right side:
