C6H14 has a lower boiling point than C11H24.
The formula H4N2O3 represents a salt containing ammonium (NH4+) and nitrate (NO3-) ions. These ions are often present in fertilisers because they effectively deliver nitrogen to plants.
The empirical formula H4N2O3 represents a salt used in fertilisers and it contains hydrogen, nitrogen, and oxygen. In this salt, the ions present are the ammonium ion (NH4+) and the nitrate ion (NO3-). Hydronium and nitrogen dioxide might also be present in the compound. However, the most relevant ions are generally the ammonium and the nitrate ions, because they are often used in fertilizers due to their abilities to effectively deliver nitrogen to plants.

Answer:
suspension
Explanation:
The volume of 0.44 moles of ethylene gas at STP is approximately 10.33 liters.
To calculate the volume of gases at Standard Temperature and Pressure (STP), we can use the ideal gas law:
PV = nRT
Where:
P = Pressure (at STP, it's 1 atmosphere, or 1 atm)
V = Volume (in liters)
n = Number of moles
R = Ideal gas constant (0.0821 L·atm/mol·K)
T = Temperature (at STP, it's 273.15 K)
Let's calculate the volume for each gas:
For 7.6 moles of Ar (argon):
P = 1 atm
n = 7.6 moles
R = 0.0821 L·atm/mol·K
T = 273.15 K
Now, plug these values into the ideal gas law:
V = (nRT) / P
V = (7.6 moles * 0.0821 L·atm/mol·K * 273.15 K) / 1 atm
V ≈ 172.75 liters
So, the volume of 7.6 moles of argon gas at STP is approximately 172.75 liters.
For 0.44 moles of C2H3 (ethylene):
P = 1 atm
n = 0.44 moles
R = 0.0821 L·atm/mol·K
T = 273.15 K
Now, plug these values into the ideal gas law:
V = (nRT) / P
V = (0.44 moles * 0.0821 L·atm/mol·K * 273.15 K) / 1 atm
V ≈ 10.33 liters
