H2SO4 is added to a large beaker of water. How is the solution different from the original water?
Natasha_Volkova [10]

Answer is: A) The solution turns blue litmus to red.

Sulfuric acid (H₂SO₄) is a strong acid, it means that the solution of sufuric acid is more acidic (pH<7) than water (pH = 7).

Chemical dissociation of sulfuric acid in water:  

H₂SO₄(aq) → 2H⁺(aq) + SO₄²⁻(aq).

When solution turns phenolphthalein pink, it means it is basic (pH>7).

Sulfuric acid has more hydrogen ions (H⁺) and less hydroxide ions (OH⁻) than water.

likoan [24]

Answer: How hydroelectric plant is better over thermal power plant in creating less pollution?

Explanation:

The thermal power plant utilizes the coal as a fuel. The heat energy so produce after burning coal is used for generating electrical energy. The burning of the coal results in the production of pollutants. The carbon dioxide is also a chief pollutant of coal burning. This can pollute the air.

The hydroelectric plant is better than thermal power plant in the sense no fuel is required for this purpose the energy from water currents are used for generating electrical energy.  

So, the citizens should research about hydroelectric plant and try to know how it is efficient in providing routine energy supply and impact it exerts on the environment if used as a source of energy generation.
