are these all sythesis reactions?

Question

1. AL + CL2---> ALCL3
2. Na + CL2---> NaCL
3. H2 + O2---> H2O
4. Mg + O2---> MgO
5. H2 + N2---> NH3

Answer 1

Yes, I think so. They're all reactions where you're combining two molecules and making one larger one.

Answer 2

I see a trend, since I am working my way backwards through these questions.

Answer yes, and you will be OK, since pretty much they all are. Once again, you could argue that Cl, O, and N are diatomic molecules . . . but you would loose.

Say yes and get an "A".
