Answer:
7.63 L is the produced volume of ammonia.
Explanation:
The balanced reaction of decomposition is this:
(NH₄)₂CO₃ (s) → 2NH₃ (g) + CO₂ (g) + H₂O (g)
We convert the mass of carbonate to moles → 15 g . 1mol / 96g = 0.156 mol
Ratio is 1:2, so the 0.156 moles will produce the double of moles of ammonia. → 0.156 . 2 = 0.312 moles
We use now, the Ideal Gases Law to determine the volume
Pressure . Volume = moles . R . T
T → 25.5°C + 273 = 298.5K
1 atm . V = 0.312 mol . 0.082 L.atm/mol.K . 298.5K
V = (0.312 mol . 0.082 L.atm/mol.K . 298.5K) / 1 atm → 7.63 L
HClO₄ + KOH → KClO₄ + H₂O
HClO₄ - perchloric acid
KOH - potassium hydroxide
We have this
<span>C M = n / V => n = C M . V = 0,25 . 0,4 = 0,1 mole </span>
<span>m Na2CO3 = n . M = 0,1 . 106 = 10,6 g</span>
Carbonate compounds have a negative valency (because they contain oxygen), so NaCO3 has a negative valency (it’s a negatively-charged ion) which makes it basic or alkaline.
