<span>Sedimentary rocks are formed when sediment is deposited out of air, ice, wind, gravity, or water flows carrying the particles in suspension. This sediment is often formed when weathering and erosion break down a rock into loose material in a source area.</span>
Answer:
An atom
Explanation:
Matter is composed of atoms and atom is further consist of smaller particles called electron, proton and neutrons.
The electron is subatomic particle that revolve around outside the nucleus and has negligible mass. It has a negative charge.
Symbol= e-
Mass= 9.10938356×10-31 Kg
It was discovered by j. j. Thomson in 1897 during the study of cathode ray properties.
While neutron and proton are present inside the nucleus. Proton has positive charge while neutron is electrically neutral. Proton is discovered by Rutherford while neutron is discovered by James Chadwick in 1932.
Symbol of proton= P+
Symbol of neutron= n0
Mass of proton=1.672623×10-27 Kg
Mass of neutron=1.674929×10-27 Kg
The atom interact with another atom by sharing or transferring the electrons. The properties of substances are depend upon the electrons present out side the nucleus.
<u>Answer:</u> In a chemical reaction, the total mass of the particles in the system stays the same
<u>Explanation:</u>
Law of conservation of mass states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form.
This also means that total mass on the reactant side must be equal to the total mass on the product side in a chemical reaction.
Every balanced chemical reaction follows law of conservation of mass.
<u>For Example:</u> Formation of water molecule
Total mass on reactant side = ![[2(2\times 1)+(2\times 16)]=36g/mol](https://tex.z-dn.net/?f=%5B2%282%5Ctimes%201%29%2B%282%5Ctimes%2016%29%5D%3D36g%2Fmol)
Total mass on product side = ![[2((2\times 1)+16)]=36g/mol](https://tex.z-dn.net/?f=%5B2%28%282%5Ctimes%201%29%2B16%29%5D%3D36g%2Fmol)
Hence, in a chemical reaction, the total mass of the particles in the system stays the same
Answer: it is the 4th option in there
Explanation:
<h2>
Answer:</h2>
Due to less inter molecular force of attraction.
<h2>
Explanation:</h2>
- Hydrosphere consist of complete water mass on earth's surface that includes ponds, lake, oceans, underground water, glaciers and water over earth's surface that is clouds, etc.
- Water exist in three phases i.e Solid(ice), Liquid(water) and Gas(water vapors).
- Solid(ice) generally are rigid.They have definite shape and volume. Hence, their kinetic energy is smaller than that of loose fluids as their particles cant move freely.
- Liquid(water) is generally more free-form than solid but they still have a definite volume, as they aim to take the shape of their container in which they are kept. The hydrogen-bonding in water makes the intermolecular forces more stronger, but inter molecular forces are not full bonds, so they are more free to move than of solids.
- Gases(water vapor) are free to move they neither have definite shape nor definite volume, they lack the inter molecular forces that hold liquids together, so they are more free to move than liquids.
Result: Water molecules in gas(vapor) phase in hydrosphere posses most kinetic energy.
