Answer:
the storm knocked down trees creating a dam blocking the path for water to move
Explanation:
The correct option is (a) H₂S : SO₂ = 2 : 2 and O₂ : H₂O = 3 : 2
<h3>What is molar Ratio ?</h3>
Molar ratio also known as stoichiometry is the ratio in which the reactants and products are either formed or reacted in the given equation
the balanced equation is as follows ;
2H₂S + 3O₂ --> 2SO₂ + 2H₂O
molar ratio can be determined by the coefficients of the compounds in the balanced reaction.
coefficient is the number in front of the chemical compound
coefficients for the compounds in this reaction are as follows ;
- H₂S - 2
- O₂ - 3
- SO₂ - 2
- H₂O - 2
therefore, correct option is (a) H₂S:SO₂ = 2:2 and O₂:H₂O = 3:2

Answer: Eutrophication is the enhancement of the growth of algae in the water body.
Explanation:
The scientists are worried for the climate change as if the climate changed to prolonged rainy then the frequent raining can remove toxic chemicals from the agricultural sites, landfills, industries, and from other locations and deposit them to the water body (river, lakes, ponds, and others). The deposition of the salts of nitrogen, phosphorus, and sulfur promotes the growth of algae in the water body. This leads to reduction in the concentration of oxygen in the water body. This is called eutrophication. The lack of oxygen can lead to mortality of aquatic animals.
