Arrange the compounds below in decreasing order of the ionic character of the bonds in them. a. CsF
b. OF2
c. SrF2
d. F2

> >    >

Explanation:

The percent ionic character is used to determine if a bond is more ionic or covalent. More is the percent ionic character, the more ionic the molecule is. If the electronegativity difference between two elements is higher than 1.7 it will be considered as ionic.

The electronegativity difference for CsF is (3.98-0.79) = 3.19

The electronegativity difference for is = (3.98-3.44) = 0.54

The electronegativity difference for is (3.98-0.95) = 3.0

The electronegativity difference for is  0.

Thus decreasing order of  ionic character of the bonds is CsF >   >    >

i think it is true since you can test the answer and can use observations to complete it.

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
