Why does an egg sink in fresh water but float in salt water??

Chemistry
1 answer:
maria [59]3 years ago
5 0
If an object is less dense than the water around it, it will float. Because salt water is denser than freshwater, some things float more easily in the ocean—or extremely salty bodies of the water, such as the Dead Sea. You can make your own dense water by adding salt to tap water.

Liquid does not act that a solid. how is it different from a solid and gas?
Wittaler [7]
Unlike solid matter, where particles are tightly packed and slightly vibrating, or gas, where particles go around everywhere and are extremely loose, a liquid has particles that are loosely packed but are still in slight contact with each other. Hope that's good enough

The radius of an atom is dependent upon which 2 things? (Two answers)
matrenka [14]

Answer:

The correct options are;

C. The magnitude of attraction from its nucleus

D. The distance between the electrons and its nucleus

Explanation:

The atomic radius reduces, within a given period, as we move from left to right, the number of protons increases alongside the number of electrons and the while the quantum shell to which the extra electrons are added to is the same. Therefore, the radius of the atom is dependent on the magnitude of the attraction from the nucleus

Similarly, as we progress to the next period, with an extra quantum shell, the atomic radius is seen to increase.

Therefore, the atomic radius is determined by the distance between the electrons and its nucleus.

Are you friend with Nitrogen and Oxygen
Oduvanchick [21]

Nitrogen and oxygen do not react at ambient temperature. At high temperatures they have endothermic reactions and produces various oxides of nitrogen.

Explanation:

The difference between nitrogen and oxygen is the nitrogen has seven protons and seven electrons surrounding the nucleus. Whereas the oxygen has eight protons and electrons.

The atoms combines with one another to form molecules. The nitrogen is a inert, colorless gas with no smell or taste, its harmless to human beings.

The oxygen and nitrogen are abundant gases in the atmosphere and have similar physical properties. The oxygen (O2) is twice as soluble in water as nitrogen (N2).
