Answer:
By adding, a few drops of AgNO3
Dilute HCl reacts with silver nitrate to give a white precipitate of silver chloride.
On the other hand there is no reaction observed when dilute Nitric acid is treated with silver nitrate solution. That is obvious
Reactions :-
HCl(aq) + AgNO3(aq) >>> AgCl(s) + HNO3(aq)
HNO3(aq) + AgNO3(aq) >>> No reaction + No precipitate
The process of splitting an atom into two nuclei is the nuclear fission
A large quantity if hydronium ions indicates an Arrhenius acid.
Answer:
15.3 g
Explanation:
- Fe₂O₃ (s) + 2Al (s) → 3Fe (l) + Al₂O₃ (s)
First we convert 8.0 grams of aluminum into moles, using its molar mass:
- 8.0 g Al ÷ 27 g/mol = 0.30 mol Al
Then we <u>convert 0.30 moles of aluminum into moles of aluminum oxide</u>, using the<em> stoichiometric coefficients</em>:
- 0.30 mol Al * = 0.15 mol Al₂O₃
Finally we convert 0.15 moles of Al₂O₃ into grams, using its molar mass:
- 0.15 mol Al₂O₃ * 102 g/mol = 15.3 g Al₂O₃
