Answer:

The answer to your question is Isotope

Explanation:

Isotopes are atoms with the same number of protons and electrons but their atomic mass is different due to their number of neutrons is different.

In this kind of elements, the number of protons stays the same.

Some isotopes are radioactive but others do not.

Some isotopes are used to know the age of fossils or ancient things.

Explain a natural process, while<br> describe a natural process.
blagie [28]

Answer:

a natural process is water cycle.

Explanation:

during this process,water evaporates from different water bodies ,when the warm water rises,the cold and heavier water comes down to take its place.On the other hand,the warm water on rising,changes to water vapour.

This water vapour helps in the formation of clouds .

When the cloud becomes heavy and is not able to hold the water vapour, it falls down as rain or snow depending upon the climate and atmospheric temperature.

This process continues over and over again

What properties of water would help water travel up the leaf?
Anna [14]
The high surface tension of water pulls the concavity outwards, generating enough force to lift water from the roots to the leaves of plants. Thus, Cohesion, along with adhesion and surface tension creates a capillary action that keeps water molecules interacting and moving through the plants out to the leaf cells.

Read about reverse osmosis and multistage flash distillation .Then identify at least three advantages and three
ss7ja [257]

Answer:

Meaning, Advantages & Disadvantages of - Osmosis, Multiflash Distillatiob

Explanation:

  • Osmosis is movement of solvent (like water) through semi permeable membrane (like living cell) into solution of higher solute concentration.

Advantages - It assists equalising concentration of solute on two sides of membrane. Reverse Osmosis is used for efficient water softening, it is easy to maintain.

Disadvantages - It needs a lot of energy. A lot of pressure is required for deionisation. Water acidity level increases, as minerals get deionised.

  • Multistage flash distillation refers to desalination water distilling seawater, by flashing water portions in steams in various stages of concurrent heat exchangers.

Advantages - Its Cost efficient , distillation uses waste heat. It has High gain output ratio. Quality of feedwater is less significant, compared to reverse osmosis.

Disadvantages - It has high operating cost in case of waste heat unavailability. High temperature imply high corrosion & scale formation.

What is the difference between inert and stable?
Katena32 [7]
Inert means that the substance did not have a tendency to react at all, while stable means that the substance has reached a chemical state in which it is not likely to react. Stability is easier to overcome than inertness.
