Answer:
Your cation is Pb2+
Explanation:
This is the explanation by chemical reactions
HCl (l) ----> H+(aq) + Cl-(aq)
Pb2+(aq) + 2Cl-(aq) ---> PbCl2 (s) ↓
H2SO4 (l) ----> 2H+ (aq) + SO4-2(aq)
Pb2+(aq) + SO4-2(aq) ---> PbSO4 (s) ↓
NaOH (l) ---> Na+(aq) + OH-(aq)
Pb2+(aq) + 2OH-(aq) ---> Pb(OH)2 (s) ↓
If the reaction takes place in a strong alkaline medium, lead hydroxide dissolves in excess of base
Answer:
K(eq) = 15 (2 sig. figs)
Explanation:
Rxn: CO(g) + 2H₂(g) ⇄ CH₃OH(l)
C(eq): 0.150M 0.360M 0.282M
Keq = [CH₃OH(l)]/[CO(g)][H₂(g)]
= (0.282M)/(0.150M)(0.360M)²
= 14.50617284 (calc. ans.)
= 15 (2 sig. figs.)
They contain the same number of molecules; however, the masses can differ depending on the molar masses of the substances.
...because hydrogen bonds are formed between ammonia molecules.
