Answer:
The pH of 0.001 M HNO3 is pH 2.0
Carbonic acid's chemical formula is H2CO3. Its decomposition to water (H2O) and carbon dioxide (CO2) is represented by the equation:
H2CO3(g) → H2O(l) + CO2(g)
Answer:
Expansion: increase in size Contraction: decrease in size
Explanation:
Answer:
T =201.4k
Explanation:
pressure = 102000pa= 1.007atm
v = 8L
n = 0.487mole
R = 0.08206Latm.mol-¹k-¹
T = ?
- using ideal gas equation
- pv=nRT
- 1.007 x 8=0.487 x 0.08206 x T
- 8.056 = 0.040 x T
- T = 8.056/0.040
- T = 201.4K
