The correct answer would be the last option. A double displacement type of reaction involves the switching of places the cations and anions accordingly. The given reaction is erroneous since in the product side the anions and cations are being paired which would not make sense. The correct reaction should be
4NaBr + Co(SO3)2 yields <span>CoBr4 + 2Na2SO3</span>
Because 1,2-diaminoethane is base, this compound gain protons from acid (in this example hydrochloric acid) and becaume ionic compound with positive charge (cation).
1,2-diaminoethane is organic compound and hydrochloric acid is inorganic compound.<span>
Balance chemical reaction:
</span>H₂NCH₂CH₂NH₂(aq) + 2HCl(aq) → ⁺H₃NCH₂CH₂NH₃⁺(aq) + 2Cl⁻(aq).
Usual s I have no idea sorry
Answer:
K = 0.167
Explanation:
The equilibrium constant, K of a reaction, is defined as the ratio of the concentrations of products and concentrations of reactants.
For the reactions:
A + B ⇄ C + D
For the definition, K is:
K = [C] [D] / [A] [B]
K = [4.0M] [4.0M] / [9.6M] [10.0M]
<h3>K = 0.167</h3>
