The rate constant for this first‑order reaction is 0.510 s−1 at 400 ∘C. A⟶products

How long, in seconds, would it take for the concentration of A to decrease from 0.990 M to 0.350 M?

particle   p is an electron and particle q is a neutron

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.
