Answer:
answer is 12.18
Explanation:
(C2H5NH2, Kb = 5.6 x 10-4.)
Answer: it’s called a phase change
Explanation: the Solid ice was melted and went through a phase change to turn into liquid matter.
Sn + 2Cl2 ---> Sn⁺⁴Cl⁻¹4
2 mol 1 mol
2.85 mol x
x=(2.85*1)/2=1.425≈1.43 mol SnCl4
Answer:
no resonance
Explanation:
Since there is only one possible lewis structure C2H2 does not have resonance. A molecule has resonance if more than one lewis structure can be drawn for that molecule. For molecules with resonance, each lewis structure individually does not accurately depict the structure of the molecule
