Electronegativity is the tendency of atom to attract shared pair of electron towards itself . Its value is out of 4 , and Fluorine is higly electronegative.
So,
D electronegativity, is the correct answer.
Answer:
0°C.
Explanation:
Hello,
In this case, given the heating curve of water on the attached document, we can notice that at 0 °C the solid starts melting, which means that the melting point is reached. Melting point is known as a physical change whereby a solid changes to liquid by the addition of heat as it allows the molecules to separate to each other.
Best regards.
Molar mass ( CuSO₄) = 159.609 g/mol
159.609 g ----------------- 6.02 x 10²³ molecules
? g ------------------ 3.36 x 10²³ molecules
mass = ( 3.36 x10²³) x 159.609 / 6.02 x 10²³
mass = 5.36 x 10²⁴ / 6.02 x 10²³
mass = 8.90 g
hope this helps!
The atoms in a solid are so attracted to each other that they vibrate and don't move past each other. The molecules of a liquid are attracted to each other, but move more freely and past one another.
