<h3>What are decomposition reactions?</h3>
- Decomposition reactions are type of reactions in which a compound is broken down into two or more products.
- When a soluble substance or a compound is dissolved in water it forms an aqueous solution.
- When this happens the soluble compound such as ionic compounds ionizes to form ions.
- This is an example of decomposition reaction, since the ionic compound decomposes it ions making it.
- For example, sodium sulfide is an ionic compound that ionizes in water to form sodium and sulfide ions.
Na₂S(s) → 2Na⁺(aq) + S²⁻(aq)
Answer:
Volume of ammonia 3 L.
Explanation:
Given data:
Temperature = 25°C ( 25+273= 298 k)
Pressure = 99.5 kpa (99.5/101 = 0.98 atm)
Volume of nitrogen = 1.50 L
Volume of ammonia = ?
Solution:
Chemical equation:
N₂ + 3H₂ → 2NH₃
Moles of nitrogen:
PV = nRT
n = PV/RT
n = 0.98 atm × 1.50 L / 0.0821 atm. L/mol. K × 298 K
n = 1.47 /24.5 /mol
n = 0.06 mol
Now we will compare the moles of nitrogen with ammonia.
N₂ : NH₃
1 : 2
0.06 : 2×0.06 = 0.12 mol
Volume of ammonia:
PV = nRT
V = nRT/P
V = 0.12 mol× 0.0821 atm. L/mol. K × 298 K/ 0.98 atm
V = 2.9 atm. L /0.98 atm
V = 3 L
Answer:
I think it's B
But A seems a good answer too
It might be D
But Imma go for C
Explanation:
Answer:
B. F⁻
Explanation:
Which anion would bond with K⁺ in a 1:1 ratio to form a neutral ionic compound?
Select the correct answer below:
A. O²⁻. NO. K⁺ and O²⁻ form K₂O in a 2:1 molar ratio.
B. F⁻. YES. K⁺ and F⁻ form KF in a 1:1 molar ratio.
C. N³⁻
. NO. K⁺ and N³⁻ form K₃N in a 3:1 molar ratio.
D. S²⁻. NO. K⁺ and S²⁻ form K₂S in a 2:1 molar ratio.
