Explanation:
From the parameters given here in this question;
n= 1.46 moles
P= 0.982 miles
T= 13°C + 273 = 286 K
R= 0.0821 L.atm/mol.K
We are to find the volume using the ideal gas equation which states that;
PV=nRT
V= nRT/P
V= 1.46 × 0.0821 × 286/0.982
V= 34.9 L
b) Boyle's law can be proven from the kinetic theory of gases. Boyle's law states the relationship between the volume and pressure of an ideal gas. Boyle's law states that the pressure of a given mass of ideal gas is inversely proportional to it's volume at constant temperature and pressure. This is the only correct statement among the options listed in the question.
Answer:
A- observation
B- hypothesis
C,D,E- experiment
F- conclusion
Explanation:
Lucia has just carried out the scientific process. An observation refers to paying close attention to a particular phenomenon in nature. This leads to the proposition of an intelligent guess about the observed phenomenon. This intelligent guess is called a hypothesis.
The hypothesis now guides the design of an experiment designed to confirm or disprove the hypothesis. The results of the experiment now leads to the formulation of a conclusion as Lucia has just done.
Answer:
since mass percent is based on the proportions of elements in a compound, the mass of a sample does not matter
Hello!
To find how many feet are in 4.3 miles you would multiply 5820 by 4.3.
Your answer would be 22,704 feet
Hope it helps!
