Write a balanced equation for the reaction of sulfur trioxide in the rain.

Sulfur trioxide has a chemical formula of SO₃. When it reacts with water, which is H₂O, the reaction is as follows:

SO₃ + H₂O → H₂SO₄

The product is sulfuric acid with a chemical formula of H₂SO₄. It is also known as acid rain.

Ans. : frostbite is when exposure to cold temperatures causes freezing to the skin or other tissues. it most commonly affects the hands, feet, and face. the longer areas are exposed to cold, typically the worse the frostbite. the water temperature used for rewarming a frostbitten part should be : (102 -105) f degrees.
