Answer: Option (d) is the correct answer.
Explanation:
A covalent bond is defined as the bond formed by sharing of electrons between the two chemically combining atoms.
For example, atomic number of chlorine is 17 and it has 7 valence electrons.
To attain stability it need to gain one more electron.
So, when one chlorine atom chemically combines with another chlorine atom then there occurs sharing of electrons between the two. As a result, there will be sharing of electrons.
A molecule is defined as the specie that contains same type of atoms which are chemically combined together in a fixed ratio by mass.

<u>Answer:</u> 120 mL of ethanol must be added.
<u>Explanation:</u>
We are given:
60% ethanol by volume
This means that 60 mL of ethanol is present in 100 mL of solution
Given volume of solution = 200 mL
Applying unitary method:
If 100 mL of solution contains 60 mL of ethanol
So, 200 mL of solution will contain = of ethanol
Hence, 120 mL of ethanol must be added.
Answer:
sublimation
Explanation:
immediately into a gas when thermal energy is added to it. The process is called sublimation. Sublimation is the change of state from a solid to a gas without going through the liquid state.
