Explanation:
mole = mass in g/ molecular weight
molecular weight of Al2O3 =2(13) + 3(16) =74g/mol
reacting mass = 27 g
mole = 27/74 = 0.36mol
Answer:
Amide
Explanation:
O=NH2 is the Amide group versus NH2, which is the amine group.
Answer:
318 kPa
Explanation:
Step 1: Given data
- Initial volume (V₁): 0.375 L
- Final pressure (P₂): 95.5 kPa
- Final volume (V₂): 1.25 L
Step 2: Calculate the initial pressure of the gas
Assuming constant temperature and ideal behavior, we can calculate the initial pressure of the gas using Boyle's law.
P₁ × V₁ = P₂ × V₂
P₁ = P₂ × V₂ / V₁
P₁ = 95.5 kPa × 1.25 L / 0.375 L = 318 kPa
Delta H = q / mass * delta temperature
