Which pair of elements can form ionic bonds?
Sindrei [870]

Answer:

E.  potassium (K) and bromine (Br)

Explanation:

An ionic bond is formed between compounds with a large electronegativity difference between them. It is usually between a metal and non-metal.

  • Potassium is a true metal found in group 1 on the periodic table.
  • Bromine is a highly electronegative non-metal which is a halogen.
  • Potassium will lose one of its electrons which will be gained by the Bromine.
  • The electrostatic attraction between the two species will cause the ionic bond to form.
  • The ability of one specie willing to lose electron and the other gaining, is the main bed rock of ionic bonding.

Answer:

Theoretical yield = 3.75g

Explanation:

Percent yield is defined as one hundred times the ratio between actual yield and theoretical yield. The expression is:

Percent yield = Actual Yield / Theoretical Yield * 100

In the problem, your actual yield was 3-00g.

Percent yield is 80.0%.

Solving for theoretical yield:

80% = 3.00g / Theoretical yield * 100

Theoretical yield = 3.00g / 80.0% * 100

<h3>Theoretical yield = 3.75g</h3>
