Simple. It always was. Time begins when matter began, so, simply put, it's always existed.
this law states that ' matter can neither be created nor destroyed in a chemical reaction". As the fundamental structural unit of matter is an atom . hence the above law can also be stated as"atom can neither be created nor destroyed in chemical reaction"
When the sun was being born, matter that was circling around it formed into planets. There was hundreds of planets, but most of them were destroyed when they crashed into each other. Eventually, only the main 8 planets were left. Then water came on earth from comets.(scientists think so anyway) and life was formed
No. Diamonds are erupted to the surface of the earth by volcanic pipes, together with other matter, including kimberlite. There is no pattern in the eruption that determines the existence of diamonds.
For a stellar black hole, yes. Mass cannot be created or destroyed. Generally a black hole will be less massive than the star from which it formed, as much of the star's mass gets blasted when the star dies in a supernova. A black hole can gain mass over time as matter falls into it.
Compounds are formed when elements of matter are chemically combined.

Due to the scientific law that states that matter cannot be created nor destroyed, it is extremely likely that all of the stars in our universe were formed from older stars that had released some or all of their matter.
Divergent: Created Collision\Subduction: Destroyed
No. Saturn has rings, but it is no way owes its existence to them. It is uncertain how the rings formed, but they may be what is left of a moon that was destroyed.
Anti matter isn't created, but "formed". No one can create matter (or anti-matter) nor destroy it.
Where is the crust neither formed nor destroyed? -In the subduction zone the crust is neither formed nor destroyed.
How are the continental plants formed and how are they eventually destroyed ? (AS 1)

a mixed compound accours when new compounds are formed
Compounds are formed when elements of matter are chemically combined.
That is a law, specifically the law of conservation of mass. This states that matter can neither be created nor destroyed in a chemical change. This was proved in Lavosier's experiment where he determined that the total lass of the products formed by burning were equal to the mass of the matter burned and oxygen consumed.
