. A 300 kg Blue car is moving rightward at 3 m/s, about to collide with a 100 kg Red car. Adjust the velocity of the Red car so that the total momentum of the system is 800 kg m/s. (Adjust the velocity
of the Red car so that the sum of the momentum of the Blue car and the momentum of the Red car
equal 800 kg m/s.) What happened?

we need the questions , i may then you.

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.
