The reason why the spectrum produced by a 1 gram sample of element z would have the same spectral lines at the same wavelengths as the spectrum produced by a 2gram is because Mass does not determine the spectral lines
hope this helps
Explanation:
Lime is added to lower the acidity of lakes when pH levels go too low.
Acidic environment is harmful to aquatic ecosystems. Acidity causes some minerals, such as phosphorus and calcium, in the water to become unavailable to aquatic organisms like plants and fishes ( This means the water hardness is reduced). The low nutrients cause stress and death in the aquatic environment lowering biodiversity. Applying lime raises the pH to neutral levels and improves the health of the aquatic life in the lake. This also improves economic activities in the lake like fishing.

Answer:
Ratio is 1:1 ; they have same number of molecules.
Explanation:
One mole of any compound have same number of molecules, irrespective of their chemistry and composition, i.e. 6.022x10^23 . This number is known as Avogadro's Number.
So the beaker with one mole of water contains = 6.022x10^23 molecules ;
and beaker with one mole of Hydrogen chloride = 6.022x10^23 molecules.
The comparative ratio is 1:1.
Answer:
