Are found along volcanic island arcs
V = maximum capacity of human lung = 3 liter = 3 x 0.001 m³ = 0.003 m³ (Since 1 liter = 0.001 m³)
P = pressure of oxygen = 21.1 kilo pascal = 21.1 x 1000 = 21100 Pa (since 1 kilo = 1000)
T = temperature of air = 295 K
n = number of moles of oxygen
Using the ideal gas equation
PV = n RT
inserting the above values in the equation
(21100) (0.003) = n (8.314) (295)
n = 0.026 moles
The metric system is used all around the world because it goes off a ten number base and is easy to calculate.
qualitative data is in words
quantitative data is in numbers
Answer:
331 g
Explanation:
Step 1: Write the balanced equation
N₂(g) + 3 H₂(g) → 2 NH₃(g)
Step 2: Calculate the moles corresponding to 400 g of ammonia
The molar mass of ammonia is 17.03 g/mol.
Step 3: Calculate the moles required of nitrogen
The molar ratio of N₂ to NH₃ is 1:2.
Step 4: Calculate the mass corresponding to 11.8 moles of nitrogen
The molar mass of nitrogen is 28.01 g/mol.
Answer:
Both have the same amount of particles.
Explanation:
From Avogadro's hypothesis, we understood that 1 mole of any substance contains 6.02×10²³ particles.
This implies that 1 mole of Hydrogen contains 6.02×10²³ particles. Also, 1 mole of oxygen contains 6.02×10²³ particles.
Thus, 1 mole of Hydrogen and 1 mole of oxygen contains the same number of particles.
