Answer:
Bothersome pollutants are pollutants that persist in water.
Explanation:
Bothersome pollutants are those pollutants that have deleterious effects on human health which are consistently lodged into water bodies. Bothersome pollutants include petroleum products, heavy metals, and toxic chemicals etc.
Many of these bothersome pollutants are non biodegradable. They accumulate at the bottom of the ocean thereby causing problems for aquatic organisms and disrupting the aquatic ecosystems in the ocean.
These bothersome pollutants are not soluble in water hence we can not just destroy them by dissolving them in water. They persist in the aquatic ecosystem and can even migrate from place to place thereby spreading pollution.
In order to balance this equation you need to count each element and how many of the individual elements are in the equation. _H2+N2=2 NH3 You multiply the 2 (Which is the coefficient) by the 3 (which is the subscript) This would equal 6 which indicated there are 6 hydrogen atoms on the right side so the left side should also have 6 hydrogen atoms
The missing coefficient on the left side must multiple the 2 to become 6 hydrogen Answer=3
Answer:
Molarity = 0.4 mol.L⁻¹
Solution:
Molarity is given as,
Molarity = Moles / Volume of Solution
Also,
Moles = Mass / M.mass
So,
Molarity = Mass / (M.mass × Volume of Solution)
Data Given,
Mass = 89 g
M.mass of Na₂SO₄ = 142 g.mol⁻¹
Volume = 1.5 L
Putting Values,
Molarity = 85 g ÷ (142 g.mol⁻¹ × 1.5 L)
Molarity = 0.399 ≈ 0.4 mol.L⁻¹
