Answer:
Explanation:
The Lewis structure of AlF₄⁻ has 32 valence electrons.
Answer:
Explanation:
Na₂S₂O₃ + 4Cl₂ + 5H₂O → 2NaHSO₄ + 8HCl.
4 moles 8 moles
4 moles of Cl₂ forms 8 moles of HCl
.25 moles of Cl₂ forms 8 x .25 / 4 moles of HCl
HCl formed = .50 moles .
E is the answer .
Answer:
False.
Explanation:
The given statement is false because for hot vacuum filtration, the filter paper should be wet rather than dry when pouring the hot solution into the Buchner funnel. This is because The possible explanation the filter paper needs to be wetted is not only to allow it to adhere to the funnel, but also to promote the solute to filter down readily across its pores of the paper without wetting it (this is true for organic and aqueous solvents).
Answer:
D). Much lower than
Explanation:
When a ketone and its enol are in equilibrium, under most conditions the concentration of the enol is <u>Much lower than</u> the concentration of the ketone
because :
Carbon- oxygen bond is more stable(stronger) than Carbon-Carbon Bond
Keto - enol tautomerism is :
Ketone has C=O and enol has C=C
C=O bond energy is 745 kJ/mol
C=C bond energy is 614 kJ/mol
