Sulfur trioxide, so3(g), reacts with water to form sulfuric acid, h2so4(g), a major component of volcanic smog. what is the balanced chemical equation for this reaction?

SO3(g) + H2O(g) H2SO4(g)   that's on edge

The chemical equation is given below.

Explanation:

Every balanced chemical equation follows Law of Conservation of mass. This law states that the total number of individual atoms on reactant side must be equal to the total number or individual atoms on the product side.

We need to write the chemical equation for the reaction of sulfur trioxide with water, the equation follows:

By Stoichiometry of the reaction:

1 mole of sulfur trioxide gas reacts with 1 mole of water molecule to produce 1 mole of sulfuric acid gas.

Hence, the balanced chemical equation is given above.

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be

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.
