<span>In the distant future, earth was no longer habitable by humans due to extreme pollution and excessive waste. Humans were not allowed to go back to earth due to the severity of the planet's condition and they dwell in space for hundreds of years while WALL-E, short for Waste Allocation Load Lifter Earth-class, was the only robot left to clean the planet, little by little.</span>
Well that is up to you what did you not know but learned recently.
Answer:
30
According to the Law of Conservation of Matter, there will be 30 atoms of product in the reaction.
LAW OF CONSERVATION OF MATTER:
The law of conservation of matter states that matter can neither be created nor produced in a chemical reaction.
This further means that the amount of matter in the reactant of a reaction must equate that of the products.
Hence, if 10 atoms of carbon (C) react with 20 atoms of oxygen (O), there will be 10 + 20 = 30 atoms of product in this reaction.
Therefore, According to the Law of Conservation of Matter, there will be 30 atoms of product in the reaction.
<span>It was a heterogeneous mixture.
Since you were able to separate the mixture than means they are heterogeneous mixture </span>
