Which of the following best represents the reaction between sulfuric acid and calcium hydroxide? f h2so4 + 2ca(oh)2 → 2caso4 + 3h2o g h2so4 + ca(oh)2 → caso4 + 2h2o h hso4 + caoh → caso4 + h2o j h2so4 + ca(oh)2 → caso4 + h2o

g. H₂SO₄ + Ca(OH)₂ → CaSO₄ + 2H₂O.

Explanation:

Sulfuric acid is represented as H₂SO₄ and calcium hydroxide is represented as Ca(OH)₂.

g. H₂SO₄ + Ca(OH)₂ → CaSO₄ + 2H₂O.

f. H₂SO₄ + 2Ca(OH)₂ → 2CaSO₄ + 3H₂O

is not correct that the no. of S, and O is not equal in both reaction sides.

S in reactants (1) while in products (2).

O in reactants (8) while in products (11).

h. HSO₄ + CaOH → CaSO₄ + H₂O

The reactants is represented in a wrong way.

j. H₂SO₄+ Ca(OH)₂ → CaSO₄ + H₂O

is not correct that the no. of H and O is not equal in both reaction sides.

H in reactants (4) while in products (2).

O in reactants (6) while in products (5).

So, the right choice is: g. H₂SO₄ + Ca(OH)₂ → CaSO₄ + 2H₂O.

acid rain does not usually kill trees directly. instead, it is more likely to weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil. the main atmospheric pollutants that affect trees are nitrates and sulphates.

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.
