Answer:

Cl + e-  → Cl-

Explanation:

The electrically neutral chlorine has 17 protons and 17 electrons, 7 of which are in its outer energy level. When an electron is added to a chlorine atom to complete its outer energy level it has more electrons than electrons. Electrons are negative and that is why the charge of chlorine becomes -1

How to solve 5gNaCl= MolE NaCl
valentinak56 [21]

0.086mole

Explanation:

The problem is very simple. It involves conversion from mass to number of moles of NaCl

What is mole?

 A mole is a unit of measuring chemical substances. It is the amount that contains the avogadro's number of particles.

How is it related and can be converted from mass;

 

Number of moles of a substance = \frac{mass}{molar mass}

Since we know the mass, we can find the molar mass and put into this equation;

Molar mass of NaCl = 23 + 35.5 = 58.5g/mol

Number of moles of NaCl = \frac{5}{58.5}  = 0.086mole
