Answer:
Physical properties
Explanation:
These properties are the ones that you can observe or collect by your senses, for example the color, the odor, the sound, the texture, etc. In this case the substance is not going to change to a new one, it could be that is changing of state.
Answer:
This is not a redox reaction.
Explanation:
A redox reaction is a reaction that involves reduction and oxidation processes. The best way to identify a redox reaction. Changes in the oxidation number f the species indicates that it is a redox reaction.
Na+
Reactant side = +1, Product Side = +1; No change
Cl-
Reactant side = -1, Product Side = -1; No change
Ag+
Reactant side = +1, Product Side = +1; No change
N
Reactant side = +5, Product Side = +5; No change
O
Reactant side = -2, Product Side = -2; No change
There is no change in any of the oxidation numbers, Hence this is not a redox reaction.
Answer:
Isotopes are atoms of the same element that have different numbers of neutrons but the same number of protons and electrons. The difference in the number of neutrons between the various isotopes of an element means that the various isotopes have different masses.

Greetings!
I believe the answer is true.
While precipitation does require a lot of energy, evaporation takes longer, and requires more energy from heat, whereas precipitation doesn't really require any.
Hope this helps you!

Because neither can be created or destroyed
