</span><span>1) Water at 0.0060 atm and 0.01° C is at its triple point.
</span>
2) The triple point is the point in the phase diagram at which the three physical states coexist: gas, liquid and solid.
3) That means that water can freeze and boil at the same time. In fact they can happen any of the six changes of phase: freezing (liquid to solid), melting (solid to liquid), evaporation (liquid to gas), condensation (gas to liquid), sublimation (solid to gas), and deposition (gas to solid).
The phase diagram is unique for any substance, meaning that it is different for different substances: the normal boiling and melting points are different.
The correct answer is (4) A large amount of energy is produced in a nuclear fission reaction.
Choice (1) is false, the products are radioactive, and often have to be buried underground for long periods of time. Choice (2) is false, because the reactants are often unstable to allow them to decay and release energy. Choice (3) is false, because the radioactive substances can affect living organisms.
Oxygen is an atom. Oxygen's atomic number is 8.
Water is a molecule that uses the Oxygen atom in it's make up:
H2O:
2 Hydrogen atoms
1 Oxygen atom.
Once I told a chemistry joke
I got no reaction.
What do you do with a sick chemistry teacher?
If you can't helium, and can't curium, you might as well barium.
I don't trust atoms,
I heard they make up everything
Hope I helped make ur day. :)
