1. How many moles of hydrogen are produced from 1.20 moles of aluminum?

1.80 moles of will be produced 1.20 moles of aluminium.

Explanation:

To calculate the moles :

The balanced chemical reaction is:

According to stoichiometry :

2 moles of produce = 3 moles of

Thus 1.20 moles of will produce=  of

Thus 1.80 moles of will be produced 1.20 moles of aluminium.

it is the most commonly accepted one

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.
