Identify balance chemical equation from the following C+O2=CO2
H2+O2=H2O
2PbO+C=Pb+CO2
Fe2O3+2Al=Al2CO3+2Fe

C+O2=CO2

Explanation:

no.of atoms on reactant side= no.of atoms on product side

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.

it’s previous models   because when i picked that son of a gun’s answer it was wrong look for previous models because they might make it a different letter
