The right response is to raise the internal gas pressure. When a sealed glass jar is heated, the temperature of the gas within rises, causing the gas molecules to travel faster and collide with the jar's walls more often and with more force, increasing the gas's pressure.
What is gas molecule?Gas molecules are made up of atoms that are linked together. These interatomic connections function similarly to springs, connecting atoms of varying masses. This connection vibrates at a constant frequency known as the natural frequency. Atoms, molecules, and/or ions are all present in gases, liquids, and solids, but their behavior varies between the three phases. The graphic below depicts the tiny differences. A gas as seen via a microscope. A gas is a condition of stuff that does not have a set volume or form. Air, water vapor, and helium are examples of gases. A gas is a kind of stuff that does not have a defined volume or shape. To put it another way, a gas takes on the shape and volume of its container.
Here,
The correct answer is Increase the internal gas pressure as When a sealed glass jar is heated, the temperature of the gas within rises, forcing the gas molecules to travel faster and hit with the jar's walls more often and with more force, raising the gas's pressure.

Action and reaction forces are described by newtons what law of motion
According to Newton, whenever objects A and B interact with each other, they exert forces upon each other. ... These two forces are called action and reaction forces and are the subject of Newton's third law of motion. Formally stated, Newton's third law is: For every action, there is an equal and opposite reaction.
There are total three laws of newtons, first law of newtons, second law of newton and third law of newton. Therefore, action and reaction forces are described by newtons third law of motion.
What is newton's third law?Newton's first law is also called law of inertia. An object at rest remains at rest, and an object in motion remains in motion at constant speed and in a straight line unless acted on by an unbalanced force.
Third law states that for every action there is an equal and opposite reaction. Third law is applicable in many field of physics. The third law is applicable in the running of rockets. The third law is also used by swimmers during swimming in pool.

metallic pan is provided with a wooden plastic handle give reason
The metallic pan iis most likely going to be used on a stove.
The stove is heating something, and the conductive metallic pan will, well, conduct that heat throughout the entire body of the pan. Doing this will spread the heat to the handle, burning your hands.
Both wood and plastic are insulators, and they do not conduct heat or electricity. They will insulate your hands and protect them from the heat.

Explain the process of sublimation. Name one substance that sublimes at room temperature and pressure.
Answer:
Here's what I get
Explanation:
Sublimation is the conversion of a solid directly to a gas, without passing through the liquid state.
It occurs when the molecules of a solid have absorbed enough heat (kinetic energy) for some molecules to overcome the attractive forces of their neighbours and escape directly into the vapor phase.
One substance that sublimes at room temperature and pressure is CO₂ (dry ice).
Naphthalene is a substance that sublimes at room temperature and pressure.
What do you mean the process of sublimation ?Sublimation is defined as a process in which solid converts into gas directly without converting into liquid.
In the sublimation process, the reaction is an endothermic reaction, as the chemical bonds between molecules are broken down in order to release them into the air. Therefore ,the energy is released and so it is an endothermic reaction.
The heat or energy required to change the state from solid to gas is called the enthalpy of sublimation .Generally, it is expressed as KJ/m o l. Sublimation only occurs at pressures and temperatures .
Hence , Naphthalene is a substance that sublimes at room temperature and pressure.

Solids, liquids and gases are the three most commonly accepted phases of matter. Explain the properties of each phase, including their relative energy.
Answer:
Here's what I get
Explanation:
The molecules of a substance attract each other.
They are also in constant motion.
Their kinetic energy increases with the temperature.
1. Solids
If the temperature is low enough, the molecules will have little kinetic energy.
They will not be able to escape the attractions of their neighbours, so they will be fixed in place in a crystalline array.
All they can do is vibrate about their position in the array.
The substance will be a solid.
2. Liquids
If the temperature is higher, the molecules will have enough kinetic energy to slide past each other, but not enough to escape the attractions of nearby molecules.
The substance will be a liquid.
3. Gases
If the temperature is high enough, the molecules will have enough kinetic energy to escape from the surface and fly off into space.
The molecules will on average so far apart that they won't feel the attractions of others.
When they do collide, they will have energy to bounce off each other rather than stick together.
The substance will be a gas.

A solution cannot dissolve any more solute even though only a small amount of solute has
been added to the solvent. This solution is
1. saturated and concentrated
2. unsaturated and dilute
3. saturated and dilute
4. unsaturated and concentrated
Answer:
Explanation:
B.) Saturated
A saturated solution is when the maximum amount of solute that could be dissolved in that solvent volume at that temperature and pressure has been dissolved, adding more solute beyond this point would lead to the additional solute not dissolving in the solvent. When the maximum solute concentration in the solution that can be dissolved has been reached the solution is said to be saturated.

The reaction 2 NO(g) ⇌ N2(g) + O2(g) has a value of Keq = 2400 at a temperature of 2000 K. If 0.570 mol of NO(g) is initially placed in a 3.0 L container, calculate the equilibrium concentrations of each gas
Answer:
[tex][N_2]_{eq}=0.094M[/tex]
[tex][O_2]_{eq}=0.094M[/tex]
[tex][NO]_{eq}=0.002M[/tex]
Explanation:
Hello,
In this case, for the given chemical reaction, we write the following law of mass action:
[tex]Keq=\frac{[N_2][O_2]}{[NO]^2}[/tex]
That in terms of the change [tex]x[/tex] due to the reaction extent (ICE procedure) we can write:
[tex]Keq=\frac{x*x}{([NO]_0-2x)^2}[/tex]
Thus, the initial concentration of nitrogen monoxide is:
[tex][NO]_0=\frac{0.570mol}{3.0L} =0.19M[/tex]
Thereby, we write:
[tex]2400=\frac{x*x}{(0.19-2x)^2}[/tex]
That we can solve by suing the quadratic equation formula or solver to obtain two roots:
[tex]x_1=0.094M\\x_2=0.096M[/tex]
Nevertheless, the correct answer is 0.094 M since the other root will produce a negative concentration of nitrogen monoxide at equilibrium, therefore, the equilibrium concentrations turn out:
[tex][N_2]_{eq}=x=0.094M[/tex]
[tex][O_2]_{eq}=x=0.094M[/tex]
[tex][NO]_{eq}=0.19M-2x=0.19M-2(0.094M)=0.002M[/tex]

Answer:
Strontium, a group 2 element with an electron configuration of 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁶ 5s² , will form a +2 ion in a chemical bond.
Explanation:
An ionic bond is produced between metallic and non-metallic atoms, where electrons are completely transferred from one atom to another. During this process, one atom loses electrons and another one gains them, forming ions. Usually, the metal gives up its electrons forming a cation to the nonmetal element, which forms an anion.
So an ion is an atom or group of atoms that have an electric charge. A cation is an ion that has a positive charge.
The alkali metals in the earth (Elements IIA) lose two electrons to form a 2+ cation. Strontium is an alkali metal that loses the two electrons belonging to 5s², forming the +2 ion.

A. Two ions can combine in only one combination.
B. The number of ions is not fixed in a compound.
C. A roman numeral is used instead of a prefix
D. A subscript follows each name instead of a prefix.
Answer:
A.
Explanation: thats what i got right on the quiz lol
Prefixes are not used in naming ionic compounds because two ions can combine in only one combination.
It is common in organic chemistry and with a few other molecular species, to name the compound using a prefix such as di, tri, tetra etc to indicate the positions of moieties in the molecule. This is important because there could be several possible combinations of atoms in a molecule.
In the case of ionic compounds, the combining ions can only have one possible arrangement.
Hence, the reason why prefixes are not used in naming ionic compounds is because two ions can combine in only one combination.

Answer:
If you look at yourself in the front of the spoon, you see that the mirror forms an inverted real image.
Explanation:
The word 'concave' means to bend inwards.
A curved mirror is a mirror that has a curved reflecting surface.
The front side of the spoon is just like a concave mirror. If you look at yourself in the front of the spoon, you see that the mirror forms an inverted real image.
Concave mirrors produce real inverted image of an object only if it is placed further away from the mirror than the focal point.

What does the kinetic theory say about the kinetic energy present in solids
Answer: The kinetic energy of solids is limited to vibrational energies..the particles are tightly bound in their crystalline structure and can only bend, flex, and vibrate about relatively fixed position. When vibrational energies exceed the strength of the force holding the particles together, the crystal structure collapses and we say the material melted. The particles can now have, in addition to its vibrational energies, rotational energy. Chunks of the collapsed crystal can, like a ball floating in water, rotate without showing much translational energy. Generally, we associate solids with vibrational kinetic energy, liquids with rotational kinetic energy, and gases with translational kinetic energy. Actually though, liquids have both vibrational and rotational energies, and gases have all three.
