When we say an object is hot, we are describing its velocity thermal energy wavelength chemical energy?

1 answer:

3 0

I think the correct answer from the choices listed above is the second option. When we say an object is hot, we are describing its thermal energy. It is the energy that comes from heat. This heat is generated by the movement of tiny particles within an object. Hope this answers the question.

The radius of a helium atom is a 31 PM. What is the radius in nanometers?

Paladinen [302]

Answer:

Thus, the radius of the helium atom in nanometers is - 0.031 nm

Explanation:

Given that:-

The radius of the helium atom = 31 pm

Considering the conversion of length in pm to the length in nm as:-

1 pm = 0.001 nm

So,

Applying the above conversion factor in the radius of helium atom as:-

Radius = $31\times 0.001$ nm = 0.031 nm

Thus, the radius of the helium atom in nanometers is - 0.031 nm

Subject: Chemistry whoever does this right will give the brainliest <3)

Andru [333]

Answer:

1 A

3 main types of bond are

Ionic bond ( formed due to complete transfer of electron between atoms(

Covalent bond ( formed by mutual sharing of electron)

Metalic bond ( present in the metals due to mobile electrons)

1 B bond in CaO is ionic bond formation in attached image

1 C hydrogen bond with nitrogen is covelent NH3 ammonia is formed because a bond between two non metals is expected to be covalent

More their electronegativity difference between hydrogen and nitrogen is less than 1.7 that makes it covalent
