Draw the lewis structure for h2so4 (h is bonded to o). draw the molecule by placing atoms on the grid and connecting them with bonds. include all lone pairs of electrons. include all hydrogen atoms. to change the symbol of an atom, double-click on the atom and enter the letter of the new atom.

Lewis structure in the attached image.

Explanation:

To draw the Lewis structure of H₂SO₄, we need to consider the octet rule: atoms gain, lose or share electrons to have 8 electrons in their valence shell. Hydrogen is an exception because its valence shell is complete with 2 electrons (duet). H, S and O are nonmetals, so they form covalent bonds to complete their valence shell, that is, they share pairs of electrons.

In the attached image is the resulting Lewis structure.

2fe + 3h2so4 -> fe2(so4)3 + 3h2

it is necessary to balance equations in order to get the proper amount of reactants as well as products in order not to make a miscalculation.

you cannot change the subscripts as that would change the substance itself. for instance, diatomic elements such as h2 only have the subscript two when a gas. another example would be so4, if you were to change the subscript, the element would no longer be sulfate.

we change the coefficients instead as that only changes the number of molecules rather than the substance itself.

hope this !
