Answer:

number of protons

The atomic number helps people identify elements according to the number of protons one atom of the element has. It essentially defines the element. While having a neutral charge, it also provides the number of electrons the element has (in one atom).

Explain why lime is added to lakes. Refer to the problem that exists and what lime does to the lakes.
aalyn [17]

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.

A student calculated the molarity of a solution prepared by dissolving 0.730 mol of table sugar (sucrose, C12H22O11) in 1.8x10^3

;

V=1.8⋅10

3 mL=1.8L;

C=0.730mol

1.8 L=0.406 M

C= 1.8L

0.730mol =0.406M

The student made a mistake because he did not convert a unit of volume from milliliters to liters. After all, molarity is defined as the number of moles of solute per liter of solution.
