According to the equation HCl + NaOH → NaCl + H2O,
the total number of moles of HCl that can be
neutralized by 80 grams of NaOH is

2 moles of HCl.

Explanation:

Given data:

Mass of NaOH = 80 g

Number of HCl neutralized by NaOH = ?

Solution:

Chemical equation:

NaOH + HCl         NaCl + H₂O

Number of moles of NaOH:

Number of moles = mass/ molar mass

Number of moles = 80 g/ 40 g/mol

Number of moles = 2 mol

Now we will compare the moles of NaOH and HCl,

               NaOH       :         HCl

                   1            :           1

                 2             :            2

Thus, 2 moles of HCl will neutralized by 80 gram of NaOH.

they are made of gases.

they have a spherical shape.

they make energy through fusion.

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
