Answer:
The answer is 18 LExplanation:
In order to find the volume , we use the formula for Boyle's law which is
[tex]P_1V_1 = P_2V_2[/tex]
where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume
Since we are finding the final volume
[tex]V_2 = \frac{P_1V_1}{P_2} \\[/tex]
From the question
P1 = 12 atm
V1 = 9 L
P2 = 6 atm
We have
[tex]V_2 = \frac{12 \times 9}{6} = \frac{108}{6} \\ [/tex]
We have the final answer as

Atoms contain positively charged protons and negatively charged electrons. Why does an ordinary atom have no charge?
Atoms contain positively charged protons and negatively charged electrons. The atoms contain the same number of protons and electrons so the positively charged protons balance out the negatively charged electrons. Therefore, an atom is electrically neutral because it has no charge.

Using the formula Q = m x ^T x Cp, solve for energy, and round your answer to the correct number of sig figs and show all work:
1) How much heat is absorbed by 1210. g water (Cp = 4.184 J/g*C) when it is heated from 20*C to 45*C
Answer:
Q = 126.5 kJ
Explanation:
Given that,
Mass, m = 1210 g
Specific heat of water, c = 4.184 J/g°C
Initial temperature, [tex]T_i=20^{\circ} C[/tex]
Final temperature, [tex]T_f=45^{\circ} C[/tex]
We need to find the heat absorbed by water. The formula that is used to find the heat absorbed is given by :
[tex]Q=mc\Delta T[/tex]
Putting all the values in it we get :
[tex]Q=1210\ g\times 4.184\ J/g^{\circ} C\times (45-20)^{\circ} C\\Q=126566\ J\\\\\text{or}\\\\Q=126.5\ kJ[/tex]
So, the amount of heat absorbed is 126.5 kJ.
How many electrons should Nitrogen (N) have around its Lewis dot model?
Answer:
5
Explanation:
5 electrons Nitrogen (N) have around its Lewis dot model. Therefore, the correct option is option D among all the given options.
What is nitrogen?Nitrogen (N), a nonmetallic element belonging to Periodic Table Group 15 [Va]. It is a colorless, flavorless, and odorless gas that makes up the majority of the atmosphere on Earth and is a component of all living things.
In terms of cosmic abundance, nitrogen is the sixth most abundant element. The main supply of nitrogen for trade and industry is the atmosphere of Earth, which contains 75.51 percent nitrogen by weight. Aside from nitrogen oxides and nitric acid, the atmosphere also includes variable tiny quantities of ammonia and ammonium salts. 5 electrons Nitrogen (N) have around its Lewis dot model.
Therefore, the correct option is option D.

For this assignment, you will develop a model that shows a roller coaster cart in four different positions on
a track. You will then use this model to discuss the changes in potential, kinetic, and thermal energy of
the cart as it moves along the track.
Answer:
This should help :)
Explanation:
The cart has a lot of potential energy, little kinetic energy, and little thermal energy when it is in position A. The kinetic energy and potential energy both rise as the cart moves towards position B, while the thermal energy rises as thermal energy from the track is transmitted to the cart through friction
What is Kinetic energy ?
Kinetic energy, which may be seen in the movement of an object, particle, or group of particles, is the energy of motion.
The cart has a lot of kinetic energy, little potential energy, and little thermal energy after it reaches position C. The cart has some thermal energy and a high potential energy at point D.
It also has a low kinetic energy. Gravity, momentum, and friction are all connected with potential energy, kinetic energy, and thermal energy, respectively.
Position A is when the potential energy is at its highest, and its kinetic energy is at its peak in position C and at its lowest in position A, whereas thermal energy is at its peak in position B and at its lowest in position A.
