Since the container of the gas is rigid, the volume of the gas will remain constant. Therefore, when the number of particles were decreased in half then the pressure will also be half of the original given they both are subjected to the same temperature.
PV = nRT
V, T and R are constants so they can be lumped together to a constant k.
P/n = k
P1/n1 = P2/n2
since n2 = n1/2
P1/n1 = P2/<span>n1/2</span>
P2 = P1/2
What does percent composition tell you about a molecule?
O A. It tells you the ratio of elements in the molecular formula.
O B. It tells you how the elements are arranged in the molecule.
O C. It gives you the total number of atoms in the molecule.
D. It tells you how much of a molecule is made up of each element.
It’s B
Answer: It states that there is a fundamental limit to what one can know about a quantum system.
Explanation:
In setting up your equipment in front of the fume hood to eliminate
any vapors during the experiment. Use an iron ring stand with iron ring to back
up the clay triangle to clasp the crucible and lid. Alter the height of the
iron ring so the end of the crucible is about one centimeter above the inner
blue cone of the strong flame.
False, because generally forensics collect the evidence to make sure the evidence doesn’t get damaged or tainted.... hope this helps
