The density of no2 in a 4.50 l tank at 760.0 torr and 25.0 °c is ________ g/l.
2 answers:
Answer:
The nitrogen dioxide gas is 4.43 g/L.
Explanation:
Pressure of the of the gas = P = 760.0 torr = 2.356 atm
(1 torr = 0.00131 atm)
Volume of the tank = 4.50 L
Temperature of the gas = 25 °C = 298 K
Moles of gas = n =
Using an ideal gas equation:
Density = 4.43 g/L
The nitrogen dioxide gas is 4.43 g/L.

Answer:
No. While gold would not react with a silver nitrate solution, nickel would.
Explanation:
Refer to the metal reactivity series.
Reactivity: .
Gold is positioned after silver in the reactivity series, meaning that gold is typically less reactive than silver. Thus, gold would not react with a solution of silver ions to produce silver metal.
However, since nickel is positioned before silver in the reactivity series, it is expected that nickel would react with silver ions in this solution to produce silver metal.
Thus, if the silver nitrate solution comes into contact with the two rings, the nickel ring would likely react with the solution, the gold ring would not.
