The burning of coal produces sulfur dioxide, so2, a pollutant that slowly reacts in air to form so3. sulfur trioxide dissolves into airborne water droplets to form a very corrosive solution of sulfuric acid. which is a product of burning coal that hastens the transformation of sulfur dioxide into sulfur trioxide?

Particles of ash

Explanation:

Sulfur is present in the coal and enters while the coal is formation under the crust in variety of forms like sulfate, sulfides, etc.

The burning of coal in the air turns this sulfur to oxidize to form sulfur dioxide. The reaction is shown below.

This gas when aided by the UV light and the particles of ash and dust which are released from burning pf coal to form sulfur trioxide gas.

This reaction of sulfur dioixde, with the fly ash involves series of the reactions which lead for formation of sulfur trioxide, .

fire could start, buildings collapsing, and ash falling from the sky.

explanation:

this is because the buildings or plants could catch on fire and the buildings would most likely collapse. lastly ash would fall because all the burning would cause ash to fall from the sky.

assuming that your periodic table has eighteen columns, you should highlight   the four elements in the third column from the left of the table.

neutral atoms of elements after calcium contain d electrons. the energy of d orbitals of a particular main shell lies between the energy of the s and p orbitals of the next main shell. for example, electrons in the have energy higher than those in the orbital while lower than those of the orbital.

by the aufbau principle, electrons fill orbitals one at a time, starting from those of the lowest energy. the orbital is therefore filled right after orbitals and before orbitals.  

potassium has electron configuration and calcium . the s orbital of a main shell holds a maximum of two electrons. the next element would thus have the electron configuration and satisfy the requirements.

a neutral atom of the element contains three electrons on top of the most recent noble gas element. it should thus be placed in the third column of the periodic table. both scandium and yttrium would satisfy the conditions. an aufbau diagram indicates that the 4f orbital is filled before the 5d. however, it appears that exceptions exists for both lanthanum and actinium. neutral atoms of the two d-block elements also demonstrate the and should be highlighted as well.
