What are 3 toxicants associated with sewage?
Answers
Final Answer:
Three toxicants associated with sewage are heavy metals, organic pollutants, and pathogenic microorganisms.
Explanation:
1. Heavy Metals: Sewage can contain heavy metals such as lead, mercury, and cadmium, which are often discharged into wastewater from industrial processes and urban runoff. These toxic metals can contaminate water bodies, accumulate in aquatic ecosystems, and pose significant health risks to both aquatic life and humans when consumed through contaminated water or seafood.
2. Organic Pollutants:*Sewage also contains a variety of organic pollutants, including pesticides, solvents, and synthetic chemicals. These substances can originate from household products, industrial discharges, and agricultural runoff. Organic pollutants can have adverse effects on aquatic ecosystems by disrupting the balance of the ecosystem, affecting water quality, and harming aquatic organisms.
3. Pathogenic Microorganisms: Sewage is a potential carrier of pathogenic microorganisms such as bacteria, viruses, and parasites. When sewage is improperly treated or discharged into water bodies without adequate disinfection, it can lead to the contamination of drinking water sources and recreational waters, causing waterborne diseases and infections in humans.
Proper sewage treatment and wastewater management are essential to minimize the release of these toxicants into the environment and protect human health and aquatic ecosystems.

Answer:
solid
Explanation:
because solid has a definite shape and volume
Answer:
Liquid
Explanation:
This is because the intermolecular forces of attraction are strong enough to hold the molecules together but not so strong as to fix them into definite positions (as in solids). Instead, they possess fluidity and hence no definite shape.

2 Which contributes to the dissolution of sugar in water?
A the dissociation of an ionic compound in water
B a strong pull of water molecules on an ionic compound
C the dissociation of a polar covalent compound in water
D a strong pull of water molecules on a polar covalent compound
Answers
These are two questions and two answers.
Question 1: Which best defines concentration?
Answer: option A, ratio that describes the amount of solute divided by the amount of solvent or solution
Explanation:
There are many different measures of concentration: percent, molarity, molality, mole fraction are some examples.
All of them express the ratio of solute to solvent or solution, in different kind of units, may be mass, number of moles, or volume.
Molarity is number of moles of solute per liter of solution. Molality is number of moles of solute per kg of solvent.
So, as you see it is always a ratio of the amound of solute, but it is not a fixed unit.
Question 2. Which contributes to the dissolution of sugar in water?
Answer: option D, a strong pull of water molecules on a polar covalent compound.
Explanation:
Sugar is not a ionic compound so it does not dissociate.
Sugar is a molecule, so it remains as such in solution.
Sugar is polar, so it can be dissolved in water that is a polar solvent (like dissolve like, is the rule).
The dissolution is explained by the fact that the pull exerted by the molecultes of solvent on the molecules of solute, is greater than the pull that the molecules of solute extert among themselves.
That permits the molecules of solvent surround the molecules of solute and get them appart of the solid substance to form the aqueous solution.
Concentration is the ratio that describes the amount of solute divided by the amount of solvent or solution; option A
The dissociation of sugar in water is due to a strong pull of water molecules on a polar covalent compound; option D
What is concentration of a solution?
Concentration of a solution is the amount of solute present in a given volume of solution.
Thus, concentration is the ratio that describes the amount of solute divided by the amount of solvent or solution.
The dissolution of sugar in water forms a sugar solution.
Sugar is a polar covalent molecule. The dissociation of sugar in water is due to a strong pull of water molecules on a polar covalent compound.
