<span>You have to use an activity series and then predict which metal by itself will replace the metal inside of the compound. These all appear to be single replacement reactions.</span>
Answer:
N = N1V1 +N2V2 +N3V3
(resultant ) ________________
V1+V2+V3
Answer:
C) It explains why mass is conserved
Explanation:
The experimental studies carried out by Antoine Laurent Lavoisier led him to conclude that in a chemical reaction, which takes place in a closed system, the sum of the masses of the reagents is equal to the sum of the masses of the products, as in the following scheme:
m (reagents) = m (products)
* Where m represents mass
Thus, for example, when 4 grams of hydrogen (H) react with 16 grams of oxygen (O), 20 grams of water (H₂O) are formed.
So also if 14 grams of carbon (C) react with 34 grams of oxygen, 48 grams of carbon dioxide (CO₂) are formed.
In short, the law of conservation explains that the proportion, by mass, of the elements that participate in the composition of a substance is always constant and does not depend on the chemical process by which the substance is obtained.
