Similes and metaphors are poetic devices. What does this
mean?
Answer:
Both similes and metaphors are a poetic device because authors can be seen using them while writing their poem to give the reader a deeper understanding of the character and the setting. Metaphor is a figure of speech that talks about one this but refers to another. On the other hand, a simile is a figure of speech that compares two things together. Usually using the work "like" or "as".

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.

determine the kinetic energy of an 833.0 kg roller coaster car moving at a speed of 20.0 m/s
Answer:
166,600J
Explanation:
Kinetic energy (K.E), which is the energy due to motion of a body, can be calculated by using the formula;
K.E = 1/2 × m × v²
Where;
K.E = kinetic energy (joules)
m = mass of body (kg)
v = speed or velocity (m/s)
According to this question, the mass of the roller coaster is 833.0 kg while its velocity/speed is 20.0m/s.
K.E = 1/2 × 833 × 20²
K.E = 1/2 × 833 × 400
K.E = 1/2 × 333200
K.E = 166,600
Therefore, the kinetic energy of the roller coaster car is 166,600J.

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

2222222c is right, but here's a better visualization of the answer!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.

I need help in this problem for an assignment. Please
Answer:
1) increases
2)increases
3) Decreases
4) increases
5) increase
6) decreases
Explanation:
Let us remember that in a solid, the molecules of the substance are trapped in fixed positions hence the entropy of a solid is less than that of liquid as well as less than the entropy of a gas.
Reaction (1) and (2) deal with a change of state from solid to liquid or gas leading to increase in entropy.
In reaction (3) the aqueous reactants convert into a liquid product leading to a decreases in entropy.
Reaction (4) and (5) has to do with change of a solid to a gas as well as an increase in volume leading to an increase in temperature.
For reaction(6), a solid is formed so entropy decreases
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.

A 5.0 balloon containing nitrogen gas is cooled from 25 degrees to 5°C. What is the final volume of the balloon?
Answer:
5.4
Explanation:
V1=5.0
T1=25+ 273=298
V2= z(unknown)
T2=5+273=278
V1/T1 =V2/T2
V2=V1T2/T1
=5*298/278
=5.4
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.
