The statement which correctly describe the relationship between the reactants and the yield is this: 'the theoretical yield is calculated from the amount of the limiting reactants present'. The theoretical yields is the ideal maximum amount of a product that can be produced during a chemical reaction while the limiting reactant is the reactant that determines the maximum amount of product that can be formed.
Well a question to ask would be if the mass of the material has changed significantly as that would determine that the substance is radioactive or if there have been any high readings found by a Geiger meter in certain period of time
hope that helps
Explanation:
xác định nội năng chuẩn ΔU của phản ứng tổng hợp amoniac
ở 400 0 C, biết :
N 2(k) + 3H 2(k) = 2NH 3(k) ΔH 0 T = - 109,0 kJ
Density is mass over volume, so:
14.3/8.46≈ 1.6903 g/cm^3
Answer:
The solution becomes diluted.
Explanation:
When you add water to a solution, the number of moles of the solvent stays the same while the volume increases. Therefore, the molarity decreases.
Hope this helps!
