What is an electron?
An electron is a negatively charged subatomic particle. It can be either free (not attached to any atom) or bound to the nucleus of an atom. Electrons in atoms exist in spherical shells of various radii, representing energy levels. The larger the spherical shell, the higher the energy contained in the electron.
What is the role of electrons?
Electrons play an essential role in numerous physical phenomena, such as electricity, magnetism, chemistry and thermal conductivity, and they also participate in gravitational, electromagnetic and weak interactions.

a side reaction occurs when acid is added to the system. which species reacts with the acid?
A side reaction occurs when acid is added to the system, so the species reacts with the acid is base.
What are acids?Acids are those species which have a pH range in between 0 to 7, generally acids are present with hydrogen atom in their molecular formula.
If in any reaction after adding the acid, side reaction wiull occur then in this condition base will reacts with the acid as it has the opposite behavior as of acid and formation of salt & water molecules takes plavce.
Hence the needed species is base.

the wind pushes a paper cup along the sand at a beach. the cup has a mass of 0.025 kg and accelerates at a rate of 5 m/s2. how much force is the wind exerting on the cup
To find the force,
⇒ must know the force's formula ⇒ F = MA
M: mass of the objectA: acceleration of the objectLet's consider the information given:
cup has a mass of 0.025kg --> 'M'accelerates at a rate of 5 m/s^2 --> 'A'Let's solve:
[tex]F=MA=0.025kg*5m/s^2=0.125N[/tex]
Thus the force is 0.125N
Answer: 0.125N

two step mole conversions, giving brainliest
Answer:
Our process will be to change the mass of NO2 to moles by dividing by the molar mass, and then we multiply the number of moles with Avogadro's number (6.02 x 10^23)
Molar mass of NO2 = (14) + (16)x2 = 46g/mol
45.8/46 = 0.99 or just 1 mole when you round it.
Now just multiply the moles with Avogadro's number
1 x (6.02 x 10^23)
= 6.02 x 10^23 molecules of NO2 reside in 45.8g of NO2

Which statement describes how a substance melts?(1 point) Molecules in the substance gain kinetic energy and then become less tightly bound to each other. Molecules in the substance gain kinetic energy and then become less tightly bound to each other. Molecules in the substance lose kinetic energy and then become more tightly bound to each other. Molecules in the substance lose kinetic energy and then become more tightly bound to each other. Molecules in the substance lose kinetic energy and then become less tightly bound to each other. Molecules in the substance lose kinetic energy and then become less tightly bound to each other. Molecules in the substance gain kinetic energy and then become more tightly bound to each other. Molecules in the substance gain kinetic energy and then become more tightly bound to each other.
Answer:
Molecules in the substance gain kinetic energy and then become less tightly bound to each other.
Explanation:
According to the forces of attraction , for a substance to melt molecules in the substance gain kinetic energy and then become less tightly bound to each other.
What are forces of attraction?Forces of attraction is a force by which atoms in a molecule combine. it is basically an attractive force in nature. It can act between an ion and an atom as well.It varies for different states of matter that is solids, liquids and gases.
The forces of attraction are maximum in solids as the molecules present in solid are tightly held while it is minimum in gases as the molecules are far apart . The forces of attraction in liquids is intermediate of solids and gases.
The physical properties such as melting point, boiling point, density are all dependent on forces of attraction which exists in the substances.
