Answer:

The grams in 3 mol of KBr are: 357 grams.

Explanation:

We calculate the weight of 1 mol of KBr

Weight KBr = Weight K + Weight Br= 39,098grams +79,904grams= 119, 002 grams/mol

1 mol KBr--------------119, 002 grams

3 mol KBr-------------x= (3 mol KBr x119, 002 grams)/ 1 mol KBr= 357, 006 grams

Why do covalent bonds form between elements with similar electronegativity?
sesenic [268]

A COVALENT BOND, FORMS BETWEEN ELEMENTS WITH SIMILAR  ELECTRONEGATIVITY AS SHARING OF ELECTRON PAIRS BETWEEN ATOMS IS EASIER AS THEY ARE IDENTICAL.

Explanation:

Bonding atoms with similar electronegativity values form covalent bonds.

A covalent bond, also called a molecular bond, is a chemical bond that involves the sharing of electron pairs between atoms.

Covalent bonds form between two nonmetal atoms with identical or relatively close electronegativity values

Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons, also it is the strength an atom has to attract a bonding pair of electrons to itself.

Pure covalent bonds result when two atoms of the same electronegativity bond. This occurs only when two atoms of the same element bond with each other.
