3. How many moles of H2SO4 (sulfuric acid) will react with 21 mol of Al? 2Al + 3H2SO4  Al2 + 3H2

pls help i really want to understand this

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.

i think is conclusions.i think so
