How many bonding electrons are in the Lewis structure of PCl₃?
Blababa [14]

Answer:

B.) 6

Explanation:

Attached below is the Lewis structure of PCl₃ . Since phosphorus (P) has 5 valence electrons and chlorine (Cl) has 7 valence electrons, there should be 26 valence electrons (5 + 7(3) = 26) in the Lewis structure.

Bonding electrons are the electrons present in the chemical bonds between two atoms.

There are 2 electrons shared in every single bond. Within PCl₃, there are 3 single bonds. As such, there are 6 bonding electrons in the Lewis structure of PCl₃.

A salt crystal has a mass 0.14mg,How many NaCl formula units does it contain?
klemol [59]
To determine the number of formula units in a sample of a compound you need to divide the number of grams by the formula mass. The formula mass of NaCl is 23 g/mol + 35.5 g/mol = 58.5 g/mol, and the number of grams of the sample is 0.14 mg * 1 g/ 1000 mg = 0.00014 g. Then the answer is 0.00014 g / 58.5 g = 2.30 * 10^ -6, which rounded to two significant figures is 2.4 * 10^ -6. So<span> the answer is 2.4 * 10^-6 or 0.0000024</span>
