Which reaction is an example of heterogeneous catalysis? A. Ethene gas reacts with hydrogen gas by using a nickel catalyst.

B. Hydrogen peroxide decomposes by using an aqueous iodide ion catalyst.

C. Formic acid decomposes by using an acidic catalyst.

D. Sulfur dioxide gas is converted to suffer trioxide gas by using nitrogen chloride gas.

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.

diaria maybe go see a doctor about that
