Explanation:
Why can't krypton and xenon separate during the separation of gases in the air?
Answer:
The remaining gas is a mixture of argon, neon, krypton, and xenon. Because these elements are chemically very unreactive, chemical means cannot be used to separate them.
Explanation:
Answer:
They're in Group 0 as they have full outer shells meaning they are chemically unreactive as they already have full outer shells meaning they don't want to lose or gain any electrons. Thus, they can't separate during the separation of gases in the air.

Answer:
Q1: Gases, liquids and solids are all made up of atoms, molecules, and/or ions, but the behaviors of these particles differ in the three phases. ... gas are well separated with no regular arrangement. liquid are close together with no regular arrangement. solid are tightly packed, usually in a regular pattern.
Q2: Mass is how much stuff something is made of. Volume is how much space an object takes up.
2) A student determined the melting point of a substance to be 55.2DC. If the accepted value
is 50.1C, what is the percent error in the student's determination?
A) 12.0 B) 5.10 C) 10.2 D) 9.24
Answer:
C) 10.2
Explanation:
Formula: Actual-Expected/Expected
The actual was 55.2 while the expected was 50.1
55.2-50.1/50.1=0.101796407 * 100= 10.2%
The percentage error in the student's determination is 10.2%
The correct answer to the question is Option C. 10.2
From the question given above, the following data were obtained:
Measured value = 55.2 °C
Accepted value = 50.1 °C
Percentage error =?Next, we shall determine the absolute error. This can be obtained as follow:
Measured value = 55.2 °C
Accepted value = 50.1 °C
Absolute error =?Absolute error = |Measured – Accepted|
Absolute error = |55.2 – 50.1|
Absolute error = 5.1Finally, we shall determine the percentage error.
Absolute error = 5.1 °C
Accepted value = 50.1 °C
Percentage error =?[tex]Percentage error = \frac{Absolute error }{Accepted value} * 100\\\\= \frac{5.1}{50.1} * 100\\\\[/tex]
Percentage error = 10.2%Therefore, the percentage error in the student's determination is 10.2%.
The correct answer to the question is Option C. 10.2

How does the entropy of a geyser system change as energy is added to the system ??
Answer:
Entropy increases as temperature increases. An increase in temperature means that the particles of the substance have greater kinetic energy. The faster moving particles have more disorder than particles that are moving more slowly at a lower temperature.
Explanation:
The entropy of the system increase as the temperature increase because at higher temperature there will be more randomness in the molecules.
What is entropy?Entropy can be described as a measure of spontaneous changes that take place in a system. In simpler words, entropy is the tendency of the universe towards disorder.
Entropy measures of randomness or disorder of a thermodynamic system and is represented by ‘S’. The value of entropy is dependent upon the amount of substance so it is an extensive property.
The change in the value of entropy depends on changes in quantities such as temperature, pressure, volume, and the number of moles of substance present in the system.
When the temperature of the system increases the kinetic energy of the molecules increases and they start to move faster. Therefore, the entropy of the geyser system increase as energy is added to the system.

What is an isotope and how are they formed?
Answer:
Long story short, isotopes are simply atoms with more neutrons — they were either formed that way, enriched with neutrons sometime during their life, or are originated from nuclear processes that alter atomic nuclei. So, they form like all other atoms.

particles of liquids have enough energy to separate from other liquid particles true or false
Answer:
False
Explanation:
I particles have enough kinetic energy to partly overcome the force of attraction between them, matter exists as a liquid. The particles can slide past one another but not pull apart completely. This explains why liquids can change shape but have a fived volume.
two oxides, X and Y are added seperately to dilute sulfuric acid and dilute sodium hydroxide. X reacts with dilute sulfuric acid but Y does not react. Y reacts with aqueous sodium hydroxide but X does not react. which type of oxide are X and Y ?
Answer:
c
Explanation:
x basic and metallic while y is acidic
The study of chemicals is called chemistry.
The correct answer is B.
The compound which has oxygen in it is called oxide. According to the question, the element is react with the acid and base.
The X only reacts with the acidic compound but not basic compound hence the element X is basic in nature. while Y only reacts with the basic compound, not X, hence the Y element is acidic in nature.
Therefore, the correct answer is B.

NH4NO3->N2O+2H2O How many grams of NH4NO3 are required to produce 33.0 games of N2O
Answer:
the moles of N2O are 33/(14.2 + 16) = 0,75 (mol)
NH4NO3 -----------> N2O + 2H2O
0.75 <--- 0.75
=> The moles of NH4NO3 are 0,75 mol
=> m = 0,75(14.2 + 4 + 16.3) = 60 (g)
Explanation:
Answer:
60 grams of NH4NO3
