All you can conclude is that something must be burning with an orange flame.
Actually, the "something" that must be burning is the hydrogen that is produced when the sodium reacts with the water:
2Na + 2H₂O → 2NaOH + H₂ + heat
So much heat is produced that the hydrogen catches fire and some of the sodium evaporates into the flame.
The electrons in the sodium atoms get "excited" in the flame. When they drop back to a lower energy level, they emit energy in the form of an orange-yellow light.
There’s nothing to answer
Answer:
I don't think you can go on without doing a reaction since you touch really anything so no you can not go without any chemical reaction I think this is the answer
I think the correct answer would be the first option. A chemical reaction that has an increase in entropy and a decrease in enthalpy is spontaneous at high temperatures. This reaction absorbs heat for it to occur so supplying heat to it is important.
The answer to this question is that <span>the strong base will require less HCl to bring the pH to 7 than the weak base.
The string base ionizes completely so the [OH-] will be neutralized faster. The weak base has an equilibrium that will constantly shift</span> to compensate for any [OH-] loss, meaning more HCl will be needed to titrate it to lower pH.
