Hey there!
N₂ has a density of 1.25 grams per liter.
We have 2.31 liters of N₂.
2.31 x 1.25 = 2.8875
We have 2.8875 grams of N₂.
Find molar mass of N₂:
N: 2 x 14
------------
28 g/mol
2.8875 ÷ 28 = 0.10
There is 0.10 mol of nitrogen in 2.31 L of N₂.
Hope this helps!
Zinc is amphoteric which means it reacts with both acids and alkalis.
The balanced equation is: Zn + 2NaOH + 2H2O --> Na2Zn(OH)4 + H2(g).
Sodium zincate and hydrogen gas are the products.
Answer:
110L
Explanation:
Boyle's Law states that P1×V1=P2×V2
Volume is indirectly proportional to Pressure so P×V is constant
P1=55atm
V1=6L
P2=3atm
V2 is to be found
P1×V1=P2×V2
6×55=3×V2
330=3×V2
Answer: V2=110L
Where’s the question tho?
