Dalton's atomic theory was based on the law of conservation of mass which states that the matter can neither be created nor be destroyed but it can only transformed into one form or another. In a chemical reaction, total mass of the reactants will be equal to the total mass of the products.
Taking an example,
Mass of 
= 16g
Mass of 
= 
Total mass on reactant side = 
Total mass on reactant side = 80g
Mass of 
= 44g
Mass of 
Total mass on product side = 
Total mass on product side = 80g
It is seen from the above example that the
total mass on reactant side = total mass on product side.
Answer:
Mass = 21.24 g
Explanation:
Given data:
Number of moles of ammonia = 7.08 mol
Mass of hydrogen reacted = ?
Solution:
Chemical equation:
3H₂ + N₂ → 2NH₃
Now we will compare the moles of ammonia and hydrogen.
NH₃ : H₂
2 : 3
7.08 : 3/2×7.08 = 10.62
Mass of hydrogen:
Mass = number of moles × molar mass
Mass = 10.62 mol × 2 g/mol
Mass = 21.24 g
Answer
1:1 is the answer.
Explanation:
All atoms want to fill their shell with electrons. You need to find the chemical compound.
Sulfur takes the two electrons from the magnesium to fill its 3p level.
It would be B because Gas is a state of matter that has no fixed shape and no fixed volume.
