Answer:
A bond in which the electronegativity difference between the atoms is between 0.4 and 1.7 is called a polar covalent bond.
A polar covalent bond is a covalent bond in which the atoms have an unequal attraction for electrons and so the sharing is unequal.
Answer:
C. identifying the half reactions
Explanation:
Answer: 35.4 grams
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.
where,
Molality = 2.65
n= moles of solute =?
= volume of solution in ml = 445 ml
Putting in the values we get:
Mass of solute in g=
Thus 35.4 grams of is needed to prepare 445 ml of a 2.65 m solution of .
