Explanation:
I did the lesson already and got it correct lol
Answer:
The final state of the substance is a gas.
The sample is initially a liquid. One or more phase changes will occur.
Explanation:
Let's consider the phase diagram for Argon (not to scale).
<em>A sample of argon is initially at a pressure of 49.6 atm and a temperature of 101.4 K. The pressure on the sample is reduced to 0.680 atm at a constant temperature of 101.4 K. Which of the following are true? Choose all that apply </em>
<em>The final state of the substance is a gas.</em> TRUE. At 0.680 atm and 101.4 K, the substance is a gas.
<em>The gas initially present will solidify.</em> FALSE. Initially, Ar is present as a liquid.
<em>The final state of the substance is a solid.</em> FALSE.
<em>The sample is initially a liquid. One or more phase changes will occur.</em> TRUE. The sample is initially liquid and only one phase change will occur.
Find volume of pillow
L=78cm
B=55cm
H=25cm




Now
Mass=5.5kg



Density of water=1000kg/m^3
As it is less than density of water it will float on water
Answer:
.259 g
Explanation:
PV = nRT
n = PV / RT
= .986 x 0.144 / .082 x 293.6
= .005897 moles
= .005897 x 44 g
= .259 g
a, c, and d are all chemical properties because they give information about how a substance will behave in the given reaction, and can’t be found without the substance undergoing some sort of chemical reaction. b, on the other hand, is a physical property—it can be determined without changing the substance’s chemical composition.
