Answer:
Actual yield = 20.52 g
Explanation:
Given data:
Theoretical yield = 25.3 g
Percentage yield = 81.1 %
Actual yield = ?
Solution:
Formula:
Percentage yield = Actual yield /theoretical yield × 100
81.1 % /100 = Actual yield / 25.3 g
0.811 = Actual yield / 25.3 g
Actual yield = 0.811 × 25.3 g
Actual yield = 20.52 g
Answer:
If the electronegativity of two atoms is basically the same, a nonpolar covalent bond will form, and if the electronegativity is slightly different, a polar covalent bond will form.
Explanation:
that's your answer very easy.

Actually Welcome to the Concept of the Ionic bonds.
Since Sodium (Na) is a cation and Chlorine (Cl) is a Anion, they both form a Ionic bond called as NaCl (common salt)
So answer is, Na and Cl
