The volume which is occupied by 0.445 mol of carbon dioxide at 397K and 973mmHg is 11.32 L.
<h3>What is ideal gas equation?</h3>
Ideal gas equation will be represented as:
PV = nRT, where
P = pressure = 973 mmHg = 1.28 atm
V = volume = ?
n = moles = 0.445 mol
R = universal gas constant = 0.082 L.atm / K.mol
T = temperature = 397 K
On putting all these values, we get moles as:
V = (0.445)(0.082)(397) / (1.28) = 11.317 = 11.32 L
Hence required volume of gas is 11.32 L.

Answer:
there are 2 types of mixtures
Explanation:
homogeneous
heterogeneous
Answer:
D. gravity, friction, and an applied force.
Explanation:
There are 4 forces that act on an airplane in motion and they are:
Gravity and drag:
It acts in a downward direction—toward the center of the Earth.
Lift:
It is the force that acts at a right angle to the direction of motion through the air. Lift is created by differences in air pressure.
Thrust:
It is the force that propels a flying machine in the direction of motion.
Options:
conduct an experiment
form a hypothesis
draw a conclusion
state the cause
Answer:
'<u>State the cause'</u> is not part of the scientific method.
Explanation:
The scientific method has three wholistic steps:
- Test the hypothesis
- Make observations from the experiment to the hypothesis
- Draw a conclusion or prediction from the experimental results.
A cause is neither a scientific term nor is it part of the processes of experimentation.
