I'm not exactly sure which one but I do know that an acid and a base react in a aqueous solution to form water, so i would probably eliminate the ones that aren't aqueous solutions.
The air escapes into the atmosphere.
An <em>emulsion</em> is a colloidal dispersion of one liquid in another liquid in which it does not dissolve.
<em>Ice cream</em> is essentially an emulsion of the fat in milk with a sugar solution trapped in a network of small ice crystals. Other chemicals are added to prevent the emulsion from separating, and air bubbles are mixed into the semisolid mixture.
<em>Up to 50 %</em> of the volume of ice cream can be air.
When the ice cream melts, the air bubbles are <em>no longer trapped</em>. They just escape into the atmosphere.
If you re-freeze the melted ice cream, its volume will be much less than the original.
Answer:
Atom
Explanation:
my theory:
Atoms are their own substance. It's atom because if you tried to break an atom, you would be going into nuclear physics. That would be unsafe and dangerous.
Answer : When the nuclear reaction produces too many neutrons.
Explanation : In a nuclear fission reactor where the reaction is controlled by regulating the number of neutrons produced by the chain reaction. Production of too many neutrons may cause an accelerated uncontrolled chain reaction which may cause enormous heat to be generated in a very short period of time inside the reactor which may result into an explosion.
For, this purpose control rods, made of neutron absorbing species, like cadmium, are placed in the nuclear reactors to control the excess number of neutrons at any point of reaction when required.
