Molar mass Argon ( Ar ) = 39.95 g/mol
39.95 g ---------------- 6.02 x 10²³ atoms
0.377 g ---------------- ( atoms Ar )
( atoms Ar ) = 0.377 x ( 6.02 x 10²³ ) / 39.95
( atoms Ar ) = 2.26954 x 10²³ / 39.95
= 5.68 x 10²¹ atoms Ar
hope this helps!
<u>Answer:</u>
<em>The energy to turn the ice into water:</em>
- The energy that is required to change the state of ice into a liquid is obtained in the form of heat energy from the ambient temperature of the warm room.
- Once this heat energy is absorbed, the individual molecules of ice gain kinetic energy and start vibrating faster.
- Yet, the temperature of the ice remains constant until the ice reaches its melting point because this energy is first utilised to break all the bonds of the lattice structure of the ice.
- After all the bonds are broken and all of the ice has changed into water, if more heat is provided again, then the temperature of the water will increase.
Answer: Option (d) is the correct answer.
Explanation:
Atomic number of carbon is 6 and its electronic distribution is 2, 4. Therefore, in order to become stable and completely fill its octet carbon readily share its valence electrons with another atom.
For example, 
A carbon atom is also able to form a double double with valence electrons of other atom.
Thus, we can conclude that a carbon atom has a strong tendency to share electrons.
