sorry i wanna play roblox so here are the rest answers> - swipe
2. - the number of atoms, types of elements, and mass of reactants and products are equal.
3. - 64 grams
4. - 1.503x10^23
5. - polar sugar molecules dissolve in water, which is polar.
6. - high temps mean more kinetic energy, which keeps sodium and chlorine ions from combining, which
increases solubility.
7. - it accepts protons and only partially dissociates in water.
8. - ph3 is stronger acid than nh3
9. - cooling a purple solution will turn it pink
